Keyless Receiver Unit Input Test
- Remove the dashboard lower cover (see DRIVER'S DASHBOARD LOWER COVER REMOVAL/INSTALLATION ).
- Disconnect the 5P connector (A) from the keyless receiver unit (B).
- 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 are OK, go to step 4.
- Reconnect the connector, and 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 step 5.
POSSIBLE CAUSECavity Wire Test condition Test: Desired result Possible cause if result is not obtained 1 BLK Under all conditions Check for voltage to ground: There should be less than 1 V. - Poor ground (G501)
- An open in the wire
3 YEL Ignition switch ON (II) Check for voltage to ground: There should be battery voltage. - Blown No. 21 (7.5 A) fuse in the under-dash fuse/relay box
- An open in the wire
5 GRY/BLU Under all conditions Check for voltage to ground: There should be battery voltage. - Blown No. 6 (7.5 A) fuse in the under-dash fuse/relay box
- An open in the wire
- Disconnect the 10P connector from the under-hood fuse/relay box, and 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, the relay module must be faulty, replace the under-hood fuse/relay box.
POSSIBLE CAUSECavity Wire Test condition Test: Desired result Possible cause if result is not obtained 2 PNK/BLK Power window master switch connector A (22P) disconnected Check for continuity between the No. 2 terminal and the power window master switch connector A terminal No. 16:
There should be continuity.An open in the wire Check for continuity between No. 2 terminal and body ground:
There should be no continuity.A short to ground in the wire
