4WD operation

[igor]

Hi All!

Background.

I have a 97 Pajero, 3Liter Automatic V6. I was told that it was an import from the US. Orig naman na leftie. Here's the stupid question. I just recently changed the tranny, so ok na yun. The indicator (the green lights for the wheels and the c/d lock) before I had the tranny replaced, when engaged on the 4WD config, the lights on the top would illuminate na steady lang. Now, after the tranny was changed, it doesn't stop blinking when on 4WD, together with the c/d lock. What could be the problem? or should I worry?

Thank you very much for the help!

Check all solenoids and vacuum lines. This may sound vague. Try going to your dealer or to Joseph Atotubo's shop to have this fixed. Medyo complicated kasi ang front drive system ng Pajero that's why it can shift to 4H even at 100kph.

I will look for the website that explains this.

In the meantime. Google the site for POCUK and the Mitsu section of 4x4wire.com

that happened to me before, it turns out may sira yung solenoid.
Try otep's suggestion check the vacuum lines and solenoids

Same thing, when I had my trusty 97 Pajero, got some problems, later I found out that it (solenoids) got wet during engine wash, it was blinking..

*Igor, when you say that "you changed the tranny" do you mean the whole transmission assembly? The vacuum lines may have something to do with your problem aside from the solenoid valves as mentioned by Doc Otep, hybrid & gregg g. It also happened to my ride (blinking front drive indicators) & the vacuum lines were the culprit. Maybe some lines were not properly re-installed.

Thank you all for the replies!

I will have the vacuum lines checked.

It was just the internals that was changed (sorry, kulang description.) Not the entire assembly.

Will it affect the 4WD operation of the vehicle (solenoid)? Or is this just an indicator that the 4WD is engaged? Reason for me asking is, I will be going on a LOOOONNNGGG road trip and I want to know if this is something to worry about. I will only have time to take the vehicle and have it checked next week.

Thanks again!

Granting the solenoids are the culprit, it will affect the 4wd/2wd operation because it(solenoids) will trigger the locking/unlocking of the axles via its vacuum operation...

[igor]

Thank you very much... All along I thought it was just an indicator. Salamat salamat!

Hi! mga guys!, ganun pala yun, I thought na normal lang na nagbiblink ang indicator for the front wheels and c/d kapag naka engage sa 4WD, hmmm, rarely ko naman kasing gamitin and 4WD mode, maganda pla mapacheck ko narin yung mga solenoids.
Nung paakyat kami ng baguio, I thought that it would be a perfect time to use it, then i noticed na parang mabigat ang steering wheel, para bang may rolling resistance. Then guys, tanong ko lang din kung kaylangan pa bang mag reverse pag nageengage sa 4WD?

hi guys i might be late about this post but i do have similar problem on our 98 pajero automatic nag bliblink ung front wheel indicator nya but not always, somtimes it blinks somtimes not, i drove it for a couple of days hindi sya nag blink pero now nag blink nanaman, redundant ung problem, nawawala sya from time to time so I suspect solenoid saan ung shop nila Joseph Atotubo para mapuntahan?

[OTEP]

Kung nawawala, mukhang vacuum problem iyan. May araw na may sufficient vacuum, may araw na kulang.

Ganun kasi sakin. I drive it one week in 4H and it can build sufficient vacuum. Pwede ko gamiting ng 2H the next week. Pero natatalo talaga yung vacuum kaya mag-blink ulit and I have to shift to 4H. In my rig, may konting leak ako sa clutch master and yun ang suspected na cause ng vacuum leak.

Maganda nga ipa-check mo na. Pero in the meantime mag-4H ka muna para hindi pwersado ang system. Yun kasi ang default setting niya. It only 'forces' itself into 2WD by using vacuum.

Btw, ganun siya so in case the system fails off-road, you will not lose 4WD capability.

San Shop ka nagpa repair ng tranny mo?Ok ba naging repair? Beside the blimking of the indicator?

up ko lang itong thread na ito..

similar problem kasi sa pajero ko..

dati ung 4WD indicator, blink ng blink.. ngayon totally wala na! i checked the fuse busted sya.. when i replaced the fuse, it got busted after few days.. san kaya ang problem nito?

ung solenoid na nabanggit dito.. ano ba itchura nun?? i want to go under and find the thing.. saan ba sya located madalas?

[OTEP]

The 'solenoids' (at least that's what they call it most of the time) is on the passenger side fender. Para siyang may rubber knob na bilog.

[afrasay]

yan ata yun vacuum switch na mayrun din sa patrol safari. eto naman yun nag control ng rear differential lock nito.

[OTEP]

Yep. Magkamukha sila ng Patrol.

ay teka! yan ba ung nasa engine bay na may hose?

or under chassis ito?
