Relay Control Module Input Test
- Remove the under-hood fuse/relay box undercover (see REMOVAL AND INSTALLATION ).
- Disconnect the under-hood fuse/relay box connector K (10P).
- 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.
RELAY CONTROL MODULE INPUT TEST - REFERENCE DATACavity Wire Test condition Test: Desired result Possible cause if result is not obtained K10 BLK Under all conditions Check for voltage to ground: There should be less than 1 V. - Poor ground (G503, G601)
- An open in the wire
K8 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
- 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.
RELAY CONTROL MODULE INPUT TEST - REFERENCE DATA
| Cavity | Wire | Test condition | Test: Desired result | Possible cause if result is not obtained |
|---|---|---|---|---|
| K7 | BLU | Under all conditions | Check for continuity between K7 terminal and the under-dash fuse/relay box connector D (17P) No. 11 terminal: There should be continuity. | An open in the wire |
| Under-dash fuse/relay box connector D (17P) disconnected | Check for continuity to ground: There should be no continuity. | A short to ground in the wire |
