Door Lock Buzzer Circuit Test
- Disconnect door lock buzzer (located behind driver kick panel). Using an ohmmeter, check resistance between buzzer terminals. Resistance should be about 1 k/ohm. Replace buzzer if necessary. If resistance is as specified, go to next step.
- While pressing transmitter button, backprobe for voltage between wireless door lock ECU terminal No. 3 (Red/Blue wire) and ground. See Figure. If no voltage exists, replace wireless door lock ECU and retest system operation. If a momentary voltage exists, check for open in buzzer circuit. See WIRING DIAGRAMS . Repair or replace circuit as necessary and retest system operation.
