Relay Control Module Input Test
- Remove the under-hood fuse/relay box under cover (see REMOVAL AND INSTALLATION ).
- Disconnect 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 to 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 control module must be faulty, replace the under-hood fuse/relay box.
WIRE AND TEST CONDITION CHARTCavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained K10 BLK Under all conditions Measure the voltage to ground:
There should be less than 0.5 V.- Poor ground (G202)
- An open in the wire
K2 YEL Ignition switch ON (II) Measure the voltage to ground:
There should be battery voltage.- Blown No. 21 (7.5 A) fuse in the driver's under-dash fuse/relay box
- An open in the wire
K8 BLU Disconnect driver's under-dash fuse/relay box D (17P) and under-hood fuse/relay box K (10P) connectors Check for continuity between the K8 terminal and driver's under-dash fuse/relay box connector D (17P) No. 11 terminal:
There should be continuity.An open in the wire Check for continuity between the K8 terminal and body ground:
There should be no continuity.A short to ground in the wire
