Power Window Master Switch Input Test
NOTE:
Before testing, troubleshoot the multiplex integrated control unit first, using B-CAN System Diagnosis Test Mode A (see
TROUBLESHOOTING - B-CAN SYSTEM DIAGNOSIS TEST MODE A
).
- Turn the ignition switch to LOCK (0).
- Remove the power window master switch (see REAR POWER WINDOW SWITCH TEST/REPLACEMENT ).
- Disconnect the 37P connector (A) from the power window master switch (B).
- Inspect the connector and socket terminals to be sure they are all making good contact.
- If the terminals are bent, loose, or corroded, repair them as necessary and recheck the system.
- If the terminals look OK, go to step 5.
- With the connector still disconnected, do the following input tests.
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, go to step 6.
Cavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained 4 GRN Under all conditions Connect terminals No. 4 and No. 13:
The driving position memory switch indicator 2 should come on.- Poor ground (G401) or an open in the ground wire
- Faulty driving position memory switch
- An open or high resistance in the wire
6 YEL Under all conditions Connect terminals No. 6 and No. 13:
The driving position memory switch indicator 1 should come on.- Poor ground (G401) or an open in the ground wire
- Faulty driving position memory switch
- An open or high resistance in the wire
26 LT BLU Under all conditions Connect terminals No. 26 and No. 13:
The driving position memory switch lights should come on.- Poor ground (G401) or an open in the ground wire
- Faulty driving position memory switch
- An open or high resistance in the wire
- Reconnect the connector to the power window master switch, and do the following input tests.
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, the door multiplex control unit must be faulty; replace the power window master switch (see REAR POWER WINDOW SWITCH TEST/REPLACEMENT ).
NOTE: After replacing the power window master switch, reset the power window control unit.Cavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained 32 BLK In all ignition switch positions Measure the voltage to ground:
