Grand Caravan FWD V6-3.3L VIN 3 Flex Fuel (2002)
Seat Track: Testing and Inspection
Passenger Power Seat Track Test
WARNING: SOME VEHICLES ARE EQUIPPED WITH SEATBACK MOUNTED AIRBAGS. BEFORE ATTEMPTING TO DIAGNOSE
OR SERVICE ANY SEAT OR POWER SEAT SYSTEM COMPONENT YOU MUST FIRST DISCONNECT AND ISOLATE THE
BATTERY NEGATIVE CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER
SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO SO COULD RESULT IN
ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
Actuate the power seat switch to move all three power seat track adjusters in each direction. The power seat track adjusters should move in each of the
selected directions. If a power seat track adjuster fails to operate in only one direction, move the adjuster a short distance in the opposite direction and
test again to be certain that the adjuster is not at its travel limit. If the power seat track adjuster still fails to operate in only one direction, refer to
Diagnosis and Testing Power Seat Switch in this section. If the power seat track adjuster fails to operate in more than one direction, perform the
following tests. For complete circuit diagrams, refer to Wiring Diagrams.
1. Check the power seat circuit breaker under the seat. If OK, go to Step 2. If not OK, replace the faulty power seat circuit breaker.
2. Check for battery voltage at the power seat circuit breaker under the seat. If OK, go to Step 3. If not OK, repair the open fused B(+) circuit to the
fuse in the Intelligent Power Module as required.
3. Remove the outboard seat cushion side shield from the seat. Disconnect the seat wire harness connector from the power seat switch connector
receptacle. Check for battery voltage at the fused B(+) circuit cavity of the power seat wire harness connector for the power seat switch. If OK, go
to Step 4. If not OK, repair the open fused B(+) circuit to the power seat circuit breaker under the seat as required.
4. Check for continuity between the ground circuit cavity of the power seat wire harness connector for the power seat switch and a good ground.
There should be continuity. If OK, go to Step 5. If not OK, repair the open ground circuit to ground as required.
5. Test the power seat switch. Refer to Diagnosis and Testing Power Seat Switch in this section. If the switch tests OK, test the circuits of the power
seat wire harness between the inoperative power seat track adjuster motor and the power seat switch for shorts or opens. If the circuits check OK,
replace the faulty power seat track unit. If the circuits are not OK, repair the power seat wire harness as required.
