Relay Control Module Input Test
NOTE:
Before testing, troubleshoot B-CAN System Diagnosis Test Mode A (see TROUBLESHOOTING - B-CAN SYSTEM DIAGNOSIS TEST MODE A
).
- Turn the ignition switch ON (II), and remove the under-hood fuse/relay box undercover (see REMOVAL AND INSTALLATION ).
- Disconnect under-hood fuse/relay box connector J (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, go to step 5.
CONNECTOR TERMINALS REFERENCECavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained J10 BLK Under all conditions Measure the voltage to ground:
There should be less than 0.5 V.- Poor ground (G301)
- An open in the wire
J8 YEL Ignition switch ON (II) Measure the voltage to ground:
There should be battery voltage.- Blown No. 21 (10 A) fuse in the driver's under-dash fuse/relay box
- An open in the wire
- Disconnect under-hood fuse/relay box connector J (10P), 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 (see REMOVAL AND INSTALLATION ).
CONNECTOR TERMINALS REFERENCECavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained J7 LT GRN Under all conditions Check for continuity between J7 terminal and the driver's under-dash fuse/relay box connector D (17P)No. 11 terminal:
There should be continuity.An open in the wire Under all conditions (Driver's 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
