Nissan Juke Service and Repair Manual : ASCD brake switch
Component Function Check
1.CHECK ASCD BRAKE SWITCH FUNCTION
With CONSULT-III
1. Turn ignition switch ON.
2. Select “ENGINE” using CONSULT-III.
3. Select “BRAKE SW1” in “DATA MONITOR” mode.
4. Check “BRAKE SW1” indication under the following conditions.
Without CONSULT-III
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-765, "Diagnosis Procedure".
Diagnosis Procedure
1.CHECK ASCD BRAKE SWITCH POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect ASCD brake switch harness connector.
3. Turn ignition switch ON.
4. Check the voltage between ASCD brake switch harness connector and ground.
*1: LHD models or RHD models with CVT *2: RHD models with M/T
Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.DETECT MALFUNCTIONING PART
Check the following.
• Harness connector E105, M77 (LHD models or RHD models with CVT)
• Harness connector M84, M201 (RHD models with M/T)
• 10A fuse (No. 3)
• Harness for open or short between ASCD brake switch and fuse
>> Repair open circuit or short to ground in harness or connectors.
3.CHECK ASCD BRAKE SWITCH INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check the continuity between ASCD brake switch harness connector and ECM harness connector.
*1: LHD models or RHD models with CVT *2: RHD models with M/T
4. Also check harness for short to ground and short to power.
Is the inspection result normal? YES >> GO TO 4.
NO >> Harness for open or short between ECM and ASCD brake switch 4.CHECK ASCD BRAKE SWITCH
Refer to EC-766, "Component Inspection (ASCD Brake Switch)" Is the inspection result normal? YES >> GO TO 5.
NO >> Replace ASCD brake switch.
5.CHECK INTERMITTENT INCIDENT
Refer to GI-42, "Intermittent Incident".
>> INSPECTION END
Component Inspection (ASCD Brake Switch)
