Test 20H - Repairing Power Door Lock Problems W/ RKE
CAUTION:
Always turn ignition off prior to disconnecting or connecting any module connector.
NOTE:
RKE module may be accessed by carefully prying each end of instrument panel top cover and sliding cover forward to disengage front clips.
- Gain access to Remote Keyless Entry (RKE) module. RKE module is located under instrument panel top cover, behind information center. Disconnect RKE module Black connector. Go to next step.
- Using DRB in voltmeter mode, check voltage on battery feed circuit (Pink wire) at RKE module Black connector. If voltage is less than 10 volts, repair open Pink wire. If voltage is more than 10 volts, go to next step.
- Using DRB in ohmmeter mode, check resistance of RKE module program enable circuit (Dark Green wire) at RKE module Black connector. If resistance is less than 10 ohms, repair short to ground in Dark Green wire. Perform TEST VER-1B . If resistance is more than 10 ohms, go to next step.
- Using DRB in voltmeter mode, check voltage on LF door unlock driver circuit (Dark Blue wire) at RKE module Black connector. Using DRB, actuate door lock relay while observing DRB voltage. If voltage is less than 10 volts, repair open Dark Blue wire. Perform TEST VER-1B. If voltage is more than 10 volts, go to next step.
- Check voltage on door lock switch unlock output circuit (Pink/Violet wire) at RKE module Black connector. Press door lock switch to UNLOCK position while observing DRB voltage. If voltage is less than 10 volts, repair open Pink/Violet wire. Perform TEST VER-1B. If voltage is more than 10 volts, go to next step.
- Check voltage on door lock switch lock output circuit (Orange/Violet wire) at RKE module Black connector. Press door lock switch to LOCK position while observing DRB voltage. If voltage is less than 10 volts, repair open Orange/Violet wire. Perform TEST VER-1B. If voltage is more than 10 volts, replace RKE module. Perform TEST VER-1B.
