Diagnostic Circuit

  1. Locate Data Link Connector (DLC) No. 3 under left side of instrument panel. See Figure. Connect voltmeter positive lead to terminal Tc and negative lead to terminal CG. See Figure. Turn ignition switch to ON position. If battery voltage does not exist, go to next step. If battery voltage exists, no problem is indicated at this time. Fault may be intermittent. If sent here from SYMPTOM TESTING, perform next test listed.
  2. Check for open or short circuit in wiring harness between cruise control ECU and DLC No. 3. See WIRING DIAGRAMS . If wiring harness and connectors are okay, replace cruise control ECU and retest system.
