ON BOARD DIAGNOSTIC SYSTEM FUNCTION


The on board diagnostic system has the following three functions.

When there is an open circuit on MIL circuit, the ECM cannot warn the driver by lighting up MIL when there is malfunction on engine control system. Therefore, when electrical controlled throttle and part of ECM related diagnoses are continuously detected as NG for 5 trips, ECM warns the driver that engine control system malfunctions and MIL circuit is open by means of operating fail-safe function. The fail-safe function also operates when above diagnoses except MIL circuit are detected and demands the driver to repair the malfunction.

HOW TO SWITCH DIAGNOSTIC TEST MODE

NOTE:

It is better to count the time accurately with a clock.

It is impossible to switch the diagnostic mode when an accelerator pedal position sensor circuit has a malfunction.

Always ECM returns to Diagnostic Test Mode I after ignition switch is turned OFF.

How to Set Diagnostic Test Mode II (Self-diagnostic Results)

1. Confirm that accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds.
2. Repeat the following procedure quickly five times within 5 seconds.
a. Fully depress the accelerator pedal.
b. Fully release the accelerator pedal.
3. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the MIL starts blinking.

WARNING
This is a usual driving condition. When a malfunction is detected twice in two consecutive driving cycles (two trip detection logic), the MIL will light up to inform the driver that a malfunction has been detected.

The following malfunctions will light up or blink the MIL in the 1st trip.

Misfire (possible three way catalyst damage)

One trip detection diagnoses Mode II Ignition switch in ON position Engine stopped

SELF-DIAGNOSTIC RESULTS
This function allows DTCs and 1st trip DTCs to be read. Engine operating condition in fail-safe mode Engine speed will not rise more than 2,500 rpm due to the fuel cut

NOTE: Do not release the accelerator pedal for 10 seconds if MIL may start blinking on the halfway of this 10 seconds. This blinking is displaying SRT status and is continued for another 10 seconds.

4. Fully release the accelerator pedal. ECM has entered to Diagnostic Test Mode II (Self-diagnostic results).

NOTE: Wait until the same DTC (or 1st trip DTC) appears to confirm all DTCs certainly.

How to Erase Diagnostic Test Mode II (Self-diagnostic Results)
1. Set ECM in Diagnostic Test Mode II (Self-diagnostic results).
2. Fully depress the accelerator pedal and keep it for more than 10 seconds. The emission-related diagnostic information has been erased from the backup memory in the ECM.
3. Fully release the accelerator pedal, and confirm the DTC 0000 is displayed.

DIAGNOSTIC TEST MODE I — BULB CHECK
In this mode, the MIL on the instrument panel should stay ON. If it remains OFF, check the bulb.

DIAGNOSTIC TEST MODE I — MALFUNCTION WARNING
This DTC number is clarified in Diagnostic Test Mode II (SELF-DIAGNOSTIC RESULTS)

DIAGNOSTIC TEST MODE II — SELF-DIAGNOSTIC RESULTS
In this mode, the DTC and 1st trip DTC are indicated by the number of blinks of the MIL as shown below.

The DTC and 1st trip DTC are displayed at the same time. If the MIL does not illuminate in diagnostic test mode I (Malfunction warning), all displayed items are 1st trip DTCs. If only one code is displayed when the MIL illuminates in diagnostic test mode II (SELF-DIAGNOSTIC RESULTS), it is a DTC; if two or more codes are displayed, they may be either DTCs or 1st trip DTCs. DTC No. is same as that of 1st trip DTC. These uniden-codes can be identified by using the CONSULT-II or GST. A DTC will be used as an example for how to read a code. A particular trouble code can be identified by the number of four-digit numeral flashes. The “zero” is indicated by the number of ten flashes. The length of time the 1,000th-digit numeral flashes on and off is 1.2 seconds consisting of an ON (0.6-second) - OFF (0.6-second) cycle. The 100th-digit numeral and lower digit numerals consist of a 0.3-second ON and 0.3-second OFF cycle. A change from one digit numeral to another occurs at an interval of 1.0-second OFF. In other words, the later numeral appears on the display 1.3 seconds after the former numeral has disappeared. A change from one trouble code to another occurs at an interval of 1.8-second OFF. In this way, all the detected malfunctions are classified by their DTC numbers. The DTC 0000 refers to no malfunction.

How to Erase Diagnostic Test Mode II (Self-diagnostic Results)

The DTC can be erased from the back up memory in the ECM by depressing accelerator pedal.

If the battery is disconnected, the DTC will be lost from the backup memory within 24 hours.

Be careful not to erase the stored memory before starting trouble diagnoses.

When a malfunction is detected for the first time, the 1st trip DTC and the 1st trip freeze frame data are stored in the ECM memory.

When the same malfunction is detected in two consecutive trips, the DTC and the freeze frame data are stored in the ECM memory, and the MIL will come on.

The MIL will go off after the vehicle is driven 3 times with no malfunction. The drive is counted only when the recorded driving pattern is met (as stored in the ECM). If another malfunction occurs while counting, the counter will reset.

The DTC and the freeze frame data will be stored until the vehicle is driven 40 times (driving pattern A) without the same malfunction recurring (except for Misfire and Fuel Injection System). For Misfire and Fuel injection System, the DTC and freeze frame data will be stored until the vehicle is driven 80 times (driving pattern C) without the same malfunction recurring. The “TIME” in “SELF-DIAGNOSTIC RESULTS” mode of CONSULT-II will count the number of times the vehicle is driven.

The 1st trip DTC is not displayed when the self-diagnosis results in OK for the 2nd trip.

Ang gulo, anliit pa ng characters sa LCD Scanguage na lang.

Or eto na lang shortcut para kay sir Wayward

Service Manual Page EC-29

To clear the codes from your ECM do as follows

How to Set Diagnostic Test Mode II (Self-diagnostic Results)
1. Confirm that accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds.
2. Repeat the following procedure quickly five times within 5 seconds.
a. Fully depress the accelerator pedal.
b. Fully release the accelerator pedal.
3. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the MI starts
blinking.
4. Fully release the accelerator pedal.
ECM has entered to Diagnostic Test Mode II (Self-diagnostic results).

How to Erase Diagnostic Test Mode II (Self-diagnostic Results)
1. Set ECM in Diagnostic Test Mode II (Self-diagnostic results).
Mode II (Self-diagnostic Results)" .
2. Fully depress the accelerator pedal and keep it for more than 10 seconds.
The emission-related diagnostic information has been erased from the backup memory in the ECM.
3. Fully release the accelerator pedal, and confirm the DTC 0000 is displayed.

or in short
.
.

Ign on count to 3
full on and off throttle 5 times within 5 sec's
count to 7 hold throttle down for 10 or so seconds
wait for the ECM light to flash let go of throttle and your in count the codes after you have written them down or fell you don’t need any codes just hold the throttle down until you see the ECM pattern change to ten fast flashes twice and then ten slow flashes and there you have one reset ECM

note: don't discount yet the possibility of SCV problem. Remember, Navara uses the exact same NipponDenso with the same part number used by Strada, Hilux, and Dmax.. It just so happen that ours have a very efficient fuel filtration (water separator and high efficiency filter) so SCV failure is very rare.

tnx sir 12vdc...the casa ran an engine diagnostic test, the injection pump needs calibration according to them. I was blown away by the cost, quoted me 35k just for the recalibration. Sabi ko wag na muna I will seek a 2nd opinion...jeeeesh!

[rpfronty]

try mo another casa or ive heard of Berima diesel in san juan, maybe you can seek another opoinion there...

do you regularly change fuel filters?

Followed the PMS sir, casa rin po nag determine if I need to change fuel filters. I have changed the fuel filters last PMS. If its not asking too much sir may contact no. po ba kayo ng berima? I am from iloilo po kasi. TIA

* 12vdc: thanks bro!
* wayward: dito sa mandaluyong yan. layo ka pala, akala ko pa nga ikaw din yung friend ko taga dito, nagpalit lang ng handle. EXACTLY the same symptoms ang nae-experience nya ngayun. 90+k km nav nya. hangang 2k rpm lang may power. sometimes while cruising parang nabubulunan pa nav nya.

as for my nav, sibak na clutch and flywheel. yari, no more 1st, 2nd, 3rd gear.

*wayward: sir, why not try the self diagnostic test first and let us know what error code lalabas. Lets check first if the ECU will also pinpoint the injection pump problem for your nav

[12vdc]

*wayward: Bagong TSB nila every 10k dapat ang change-filter interval, baka hindi nasunod ng casa. Try mo pa diagnose sa denso shops or central diesel. Search modin sa international site, it could be as simple as grounding problem. Hindi pa ako nag llimp mode ever since pero pag nangyari yun madali na mag elimination method sa troubleshooting..

as for my nav, sibak na clutch and flywheel. yari, no more 1st, 2nd, 3rd gear.

Maganda project yan, launch mode sa 4th gear.

Isa pa yan sa dapat palitan pag nag chips. Di talaga tatagal oem clutch sa added torque.. Anu plan mo exedy or extremeclutch?

Ang complain ko lang sa M/T may konting salyada saka yung parang tansan na tunog pag loaded..

my golly , this is great work sir, now you can copyright this and have it mass produced..hehehe

keep us updated sir regarding sa outcome , thanks

Yup, same here sir, nagpalit na rin ako ng flywheel

*rpfronty- thanks po sir..

I opted to have the casa remove the injection pump and pa calibrate ko na lng dyan sa manila, para labor na lng babayaran ko (3k plus). I saw an ad sa Sulit of a shop specializing in CRDI injection pumps. 18k charge nila with 6mos warranty, its still a far cry from what the casa quoted me. At may pointers daw sila ibibigay pagkatapos on how to increase longevity ng pumps natin (share ko na lng). BTW, hindi daw isolated sa Nav ito, marami na sya nagawa na injenction pumps ng ibang vehicle makes. The culprit daw is dirty fuel Npakarumi pala ng diesel dito sa amin, there was another Nav dito (4x4) same prob with mine sabi ng casa dito..

Thanks Guys..

[wayward]

Another thing sir, my nav has a chip, d kaya dahil din sa chip? had it for six mos. or so...baka na stressed out ung pump dahil sa chip which increases the commonrail pressure

[BoyBakaL]

Sir wayward mines got my SCV changed before the 3 year warranty was over buti na lang at 20tkm lol...

eratic at first then gets worse as you use it

Even if you use SHELL Vpower diesel if the fuel is dirty ganun din mangyayari.. i been using shell diesel power for a year but my other crdi egine also got SCV issue after it.. Its worse using Vpower coz konti lang bumibili kaya mas stagnant ang diesel nila lalo dumudumi..

[DeathRow]

How much price range for 20k PMS?

[wayward]

good for you sir boybakal, nakahabol po kayo. btw, error code is p127 daw

[12vdc]

P0127 Intake Air Temperature Sensor

Broken MAF?

[franster]

Hey guys, in you own opinion, is it worth it to upgrade my current stock head unit (the one that plays audio cd's only) of my nav to a latest kind of the stock head unit of the navara which already plays mp3 and with aux in? someone offered me his stock head unit from his newly purchased nav for P10,000. (he's selling them coz he upgraded to a touch screen head unit na) Worth it ba for that price? Planning to sell also my current stock head unit if I pursue on upgrading it. How much rin kaya if I'm gonna sell my stock head unit?

[12vdc]

^ IMO, for 10k you could have a decent 2DIN china touchscreen with AV & reverse cam input. Just add more and maybe a GPS header or a built in GPS.

Stocker can be traded to some shops but no idea about pricing, maybe around 4k?
Mine is in the stockroom since it doesnt fit to older cars in the garage.

Hi there. I was also considering those 2din china head units but I'm a bit skeptical on how its sound quality would be. I think that I'll just stay with the latest stocker ones in which I'm pretty sure that will sound as good as the stock HU that I have in my nav, or is it different now?? hmmm..

As for the price pala, he said that the amount is still negotiable. :-)

[rpfronty]

whats a good branded basic head unit to replace the OE one? at least may aux input sa harap or usb...
