Component Function Check
1.CHECK ASCD STEERING SWITCH FUNCTION
1. Turn ignition switch ON.
2. Check the voltage between ECM harness connector terminals under the following conditions.
Is the inspection result normal? YES >> INSPECTION END
NO >> Go to EC-1011, "Diagnosis Procedure".
Diagnosis Procedure
1.CHECK GROUND CONNECTIONS
1. Turn ignition switch OFF.
2. Check ground connection E38. Refer to Ground inspection in GI-44, "Circuit Inspection".
Is the inspection result normal? YES >> GO TO 2.
NO >> Repair or replace ground connection.
2.CHECK ASCD STEERING SWITCH CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch OFF.
2. Disconnect combination switch (spiral cable) harness connector.
3. Disconnect ECM harness connector.
4. Check the continuity between combination switch (spiral cable) harness connector and ECM harness connector.
5. Also check harness for short to ground and short to power.
Is the inspection result normal? YES >> GO TO 4.
NO >> GO TO 3.
3.DETECT MALFUNCTIONING PART
• Harness connector E105, M77 • Combination switch (spiral cable) • Harness for open or short between ECM and combination switch
>> Repair open circuit or short to ground or short to power in harness or connectors.
4.CHECK ASCD STEERING SWITCH INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Check the continuity between combination switch (spiral cable) harness connector and ECM harness connector.
2. Also check harness for short to ground and short to power.
Is the inspection result normal? YES >> GO TO 6.
NO >> GO TO 5.
5.DETECT MALFUNCTIONING PART
• Harness connector E105, M77 • Combination switch (spiral cable) • Harness for open or short between ECM and combination switch (spiral cable)
>> Repair open circuit or short to ground or short to power in harness or connectors.
6.CHECK ASCD STEERING SWITCH
Refer to EC-1012, "Component Inspection".
Is the inspection result normal? YES >> GO TO 7.
NO >> Replace ASCD steering switch.
7.CHECK INTERMITTENT INCIDENT
Refer to GI-42, "Intermittent Incident", ???GROUND INSPECTION??? and ???INCIDENT SIMULATION TESTS???.
>> INSPECTION END
Component Inspection
