Test Procedures
- Using ohmmeter, check continuity between pin No. 2 of Brown connector and ground. See KEYLESS ENTRY MODULE CONNECTOR TERMINAL IDENTIFICATION in Fig. Figure of TEST A. If continuity exists, go to next step. If no continuity exists, repair open in Black wire and repeat QUICK TEST .
- With ignition off, press any button on keypad. If both keyholes light, go to step 5). If one or both keyholes do not light, go to next step.
- Disconnect Green connector. Check for short between pins No. 6 and 12 of Green connector. Also check continuity between pin No. 12 and inoperative door lock cylinder connector. If circuits are okay, go to next step. If not, repair open or short in Black/Pink wire and repeat QUICK TEST .
- Reconnect Green connector. Connect voltmeter between pin No. 12 of Brown connector and ground. Lift up door handle on front doors (one at a time) and check voltmeter. If readings are 10 volts or more (within 15 seconds), replace inoperative lock cylinder and repeat QUICK TEST . If readings are less than 10 volts, go to next step.
- Check voltage between pin No. 13 of Brown connector and ground. If reading is 10 volts or more, go to next step. If reading is less than 10 volts, check fuse and circuits No. 54B and 54C. Repeat the QUICK TEST .
- Check voltage at pin No. 8 of Brown connector with ignition switch in "RUN" and "OFF" positions. If reading is 10 volts or more in "RUN" position, go to next step. If reading is more than zero volts with ignition off or less than 10 volts in "RUN" position, repair open or short in Pink wire going to ignition switch. Repeat QUICK TEST .
- Check continuity between pin No. 11 of Brown connector and ground as each door handle is lifted. No continuity should exist when handles are released. If handle switch is okay, go to step 10). If no continuity exists when handles are lifted, go to step 9). If continuity exists when handles are released, go to next step.
- Disconnect both door handle connectors and Brown connector. Check for short to ground between pin No. 11 of Brown connector and ground. If no continuity exists, replace handle switch and repeat QUICK TEST . If continuity exists, repair short to ground and repeat QUICK TEST .
- Check continuity between pin No. 11 of Brown connector and inoperative door handle switch connector(s) which failed step 7). If no continuity exists, repair circuit No. 465 and repeat QUICK TEST . If continuity exists, replace handle switch and repeat QUICK TEST .
- Reconnect both Brown and Green connectors. Turn ignition off and check voltage between pin No. 12 of Green connector and ground as door handle is lifted. If reading is 10 volts or more (within 30 seconds), go to next step. If reading is less than 10 volts, replace keyless entry module and repeat QUICK TEST .
- Momentarily connect a jumper wire across pins No. 2 and 12 of Green connector. If interior lights come on, go to next step. If not, repair short or open in circuits No. 53 and 54. See KEYLESS ENTRY SYSTEM WIRING DIAGRAM. Repeat QUICK TEST .
- Check Green and Brown connectors for corroded, loose, or broken pins. Repair or replace connectors as required. If connectors are okay, replace keyless entry module. Repeat QUICK TEST .
