PARK/NEUTRAL POSITION SWITCH (M/T)

Description

INFOID:0000000000965468

Park/neutral position switch provides input signals to ECM, which transmits the data to ICC sensor integrated
unit with CAN communication. 
ICC sensor integrated unit performs the following controls via park/neutral position switch. 
• Rejects any attempt to set ICC system when M/T shift knob is set at neutral position. 
• Cancels ICC system when M/T shift knob is set to neutral position. 

Component Function Check

INFOID:0000000000965469

1.

CHECK OPERATION OF PARK/NEUTRAL POSITION SWITCH

With CONSULT-III

With “ICC” of “DATA MONITOR”, check if “NP SW SIG” operate normally.

Is the inspection result normal?

YES

>> INSPECTION END.

NO

>> GO TO 

CCS-81, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000000965470

1.

CHECK PARK/NEUTRAL POSITION SWITCH CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect park/neutral position switch connector and ECM connector.

3.

Check continuity between park/neutral position switch harness connector and ECM harness connector. 

4.

Check continuity between park/neutral position switch harness connector and ground. 

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> GO TO 2.

2.

REPAIR OR REPLACE HARNESS BETWEEN PARK/NEUTRAL POSITION SWITCH AND ECM

Repair or replace harness between park/neutral position switch and ECM.

>> GO TO 10.

3.

CHECK PARK/NEUTRAL POSITION SWITCH GROUND CIRCUIT

Check continuity between park/neutral position switch harness connector and ground.
