Test 1: Power & Ground Circuit Check
- Check ASCD Control Unit Power Supply
Turn ignition switch to LOCK position. Disconnect ASCD control unit harness connector. Turn ignition switch to ON position. Turn ASCD switch on. Measure voltage at terminal No. 5 (Pink/Blue wire) at ASCD control unit harness connector. See Fig 1
. If battery voltage exists, go to next step. If battery voltage does not exist, inspect fuse No. 8 (10-amp) in fuse block. Replace as needed.
- Check ASCD Control Unit Ground Circuit
Turn ignition switch to LOCK position. Check for continuity between ground and terminal No. 17 (Black wire) at ASCD control unit harness connector. See Fig 1
. If continuity exists, circuits are okay. If continuity does not exist, repair open in Black wire. See WIRING DIAGRAMS
