Interrupt Relay
- Turn ignition off. Remove interrupt relay, located near cruise control module. Check for continuity between interrupt relay terminals No. 1 (Gray wire) and No. 4 (Blue/Red wire). See Fig 1
. If continuity exists, go to next step. If continuity does not exist, replace relay.
- Check for continuity between interrupt relay terminals No. 2 (Blue/Red wire) and No. 6 (Blue/White wire). If continuity exists, go to next step. If continuity does not exist, replace relay.
- Connect battery voltage to interrupt relay terminal No. 4 (Blue/Red wire) and connect ground to relay terminal No. 1 (Gray wire). Check for continuity between relay terminals No. 2 (Blue/Red wire) and No. 6 (Blue/White wire). Continuity should not exist. If continuity exists, replace relay.
