kimps: if the 4WD light is always ON then 2 things you can check:

a. 4WD indicator switch. Location: under the dash, coming from the instrument cluster the wire is 0.5mm2 and colored LIGHT GREEN. Trace this and it goes to the 4WD indicator switch. On the other side of the switch is a 0.85mm2 BLACK wire. This is a normally open switch. Baka shorted na.

b. The other side of the switch is GROUND so baka naka short na sa ground yung harness kaya umiilaw.

Pinaka madali: remove the bulb sa cluster.

OBDII (on Board Diagnostics II) almost the same as the TECH 2

Lord Boybi,

alam mo ito lang ang masasabi ko pag electronic or computer controlled ipa diagnostics mo siya kasi chinecheck niya yung sensors from all points of angle... meaning anything na computer controlled may sensors yan that detects the efficiency..

ngayon.... kung hula hula yan di pwede (pero sa mga mecha na engine na walang ecu pwedeng pwede) so the best bet is to have it check sa casa ngayon maaring sabihin sayo nang friendster mong Service Adviser na iiwan ang unit mo dahil they need time to analyze and get the readings./.. if check engine yan.... try mo suggestions ni Jappy na sa fuel sensor mo or sa fuel line mo


Lord Kimpy,

Ay... sabi ko naman sayo eh yung sensors lang naman yan prob mo eh... either ground or busted na ang sensors mo...


MBT,

Injection pumps lalo na sa mga quality nang Diesel natin ay may prob. talaga even the most sophisticated ECU can't handle the dirty fuel dito this is the case of KCBOY (yahoo..... miss ko na yan trooper mo)


This is one classic case of the sensors failing.... (kc, with your indulgence ha)

si Kc may trooper yan... once kinontak ako ni kc na kinukwento niya na ang minumulto ang trooper niya.. All the lights flashes and the wiper.. pero there is a certain time niya.. so tawag ko dun sinasapian..

so off we went then..... sa diagnostics d siya lumabas pero what they did is clean the sensors and retroffited and traced the wires. they reset the settings of the ECU (in short finormat) then run a final test on the readings running the engine at 1500 to 2000

Lord Boybi,

TECH 2 is a ON BOARD DIAGNOSTIC TOOL which takes a snapshot of the reading from your ECU to the diffeerent parts of the car usually they get the reading from the different sensor positioned at the different parts of the engine.. (in short lahat nang nagamit nang ECU dapat tinetech 2 para di hula)

so ayun HTH (or nakagulo pa ako)
