Keyless Receiver Unit Input Test
- Remove the driver's 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 look 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.PROBLEM SYMPTOM TABLE
Cavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained 1 BLK Under all conditions Measure voltage to ground:
There should be less than 1 V.- Poor ground (G502)
- An open in the wire
3 YEL Ignition switch ON (II) Measure voltage to ground:
There should be battery voltage.- Blown No. 10 (7.5 A) fuse in the under-dash fuse/relay box
- An open in the wire
Ignition switch OFF Measure voltage to ground:
There should be no voltage.Short to power on No. 10 (7.5 A) fuse circuit 5 WHT/RED Under all conditions Measure voltage to ground:
There should be battery voltage.- Blown No. 9 (10 A) fuse in the under-hood fuse/relay box
- Faulty under-dash fuse/relay box
- An open in the wire
- Disconnect the connector, and make this input test at the connector.
- If the test indicates a problem, find and correct the cause, then recheck the system.
- If the input test proves OK, replace the keyless receiver unit.PROBLEM SYMPTOM TABLE
Cavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained 2 BLU/ORN Ignition switch OFF, under-dash fuse/relay box connector K (17P) disconnected Check for continuity between the No. 2 terminal and the No. 2 terminal of the under-dash fuse/relay box connector K (17P):
There should be continuity.An open in the wire Check for continuity between the No. 2 terminal and body ground:
There should be no continuity.A short to ground in the wire
