Check Output Signal To Integrated Module
OUTPUT SIGNAL INTEGRATED MODULE REFERENCE
| Step | Check | Yes | No |
|---|---|---|---|
| 1 CHECK OUTPUT SIGNAL. Measure the voltage between the keyless entry control module harness connector terminal and chassis ground when UNLOCK/DISARM button of transmitter is pressed. Connector & terminal (B176) No. 18 (+) - Chassis ground (-): |
Is the measured value more than 10 V? | Go to step 2. | Replace the keyless entry control module. |
| 2 CHECK OUTPUT SIGNAL. Measure the voltage between the keyless entry control module harness connector terminal and chassis ground when LOCK/ARM button of transmitter is pressed. Connector & terminal (B176) No. 19 (+) - Chassis ground (-): |
Is the measured value more than 10 V? | Go to step 3. | Replace the keyless entry control module. |
3 CHECK HARNESS BETWEEN KEYLESS ENTRY CONTROL MODULE AND INTEGRATED MODULE.
|
Is the measured value less than 10 Ω? | Replace the integrated module. | Check the harness for open circuit or shorts between the keyless entry control module and integrated module. |
