Nissan Juke Service and Repair Manual : ASCD main switch
Component Function Check
1.CHECK ASCD MAIN 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-1009, "Diagnosis Procedure".
Diagnosis Procedure
1.CHECK ASCD MAIN SWITCH POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect combination switch (spiral cable) harness connector.
3. Turn ignition switch ON.
4. Check voltage between combination switch (spiral cable) harness connector and ground.

Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.DETECT MALFUNCTIONING PART
Check the following.
• Combination switch (spiral cable)
• 10 A fuse (No. 2)
• Harness for open and short between combination switch (spiral cable) and
ground.
>> Repair open circuit, short to ground or short to power in harness or connectors.
3.CHECK ASCD MAIN SWITCH INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check the continuity between ECM harness connector and combination switch (spiral cable) harness connector.

4. Also check harness for short to ground and short to power.
Is the inspection result normal? YES >> GO TO 5.
NO >> GO TO 4.
4.DETECT MALFUNCTIONING PART
Check the following.
• Harness connector E105, M77 • Combination switch (spiral cable) • Harness for open and short between ECM and combination switch (spiral cable)
>> Repair open circuit, short to ground or short to power in harness or connectors.
5.CHECK ASCD STEERING SWITCH
Refer to EC-1010, "Component Inspection".
Is the inspection result normal? YES >> GO TO 6.
NO >> Replace ASCD steering switch.
6.CHECK INTERMITTENT INCIDENT
Refer to GI-42, "Intermittent Incident", ???INCIDENT SIMULATION TESTS??? and ???GROUND INSPECTION???.
>> INSPECTION END
Component Inspection
1.CHECK ASCD STEERING SWITCH-I
1. Turn ignition switch OFF.
2. Disconnect combination switch (spiral cable) harness connector.
3. Check the continuity between combination switch (spiral cable) harness connector terminals under the following condition.

Is the inspection result normal? YES >> GO TO 2.
NO >> Replace ASCD steering switch.
2.CHECK ASCD STEERING SWITCH-II
Check resistance between combination switch (spiral cable) harness connector terminals under the following conditions.

Is the inspection result normal? YES >> INSPECTION END
NO >> Replace ASCD steering switch.
