ASCD Steering Switch Check
- Turn ignition off. Disconnect ASCD control unit harness connector. Measure resistance between terminals No. 11 and 24 on harness connector while pressing each switch, one at a time. See Figure. See STEERING SWITCH CIRCUIT TEST table. If resistance is as specified, steering switch is okay. If resistance is not as specified, go to next step.
- Disconnect ASCD steering switch harness connector. Check continuity of circuits between ASCD steering switch and ASCD control unit. See WIRING DIAGRAMS . If continuity is present in both circuits, replace steering switch. If continuity is not present in either circuit, repair suspect circuit as needed.
