Honda Fit/Jazz - Power Window Master Switch Input Test
Power Window Master Switch Input Test
NOTE: The power window control unit is built into the power window master switch, and it only controls the driver's window operations.
| 1. | Remove the power window master switch (A).
|
| 2. | Disconnect the 20P connector (B) from the master switch.
 |
| 3. | 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, make the following input tests at the connector.
- If a test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, go to 4.
|
| 4. | With the connector still disconnected, 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, go to 5.

|
| 5. | Reconnect the 20P connector to the switch, and perform 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 control unit must be faulty; replace the power window master switch.
