Master Switch Input Test
Master Switch Input Test1. Before testing the power windows, troubleshoot the multiplex integrated control system using B-CAN System Diagnosis Test Mode A.
2. Remove the driver's door switch trim.
- 2-door
- 4-door
3. Disconnect the 23P connector (A) from the power window switch (B).
4. 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.
5. Reconnect the 23P connector to the switch.
6. Turn the ignition switch to ON (II) to keep the system awake and perform the 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 7.
NOTE: Reference voltage is approximately 5 V when system is awake. The voltage drops to 0.8 V when the system goes into sleep mode.
7. Disconnect the 22P connector from the power window master switch, and make these input tests at the connector.
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, the control unit must be faulty; replace the power window master switch.
