Malfunction in Park / Neutral Position Switch - Vehicle Stability Control System

BRAKE CONTROL: VEHICLE STABILITY CONTROL SYSTEM: C1207/37: Malfunction in Park / Neutral Position Switch
C1207/37 - Malfunction in Park / Neutral Position Switch

DESCRIPTION

The park / neutral position switch signal is sent to the skid control ECU via the CAN communication system.

When there is a malfunction in the CAN communication system, it will be detected by the diagnostic function.

INSPECTION PROCEDURE

NOTICE:
When replacing the VSC actuator assembly, perform zero point calibration Calibration.

PROCEDURE

1. CHECK CAN COMMUNICATION SYSTEM

(a) Check if a CAN communication system DTC is output How to Proceed With Troubleshooting.

Result





B -- GO TO CAN COMMUNICATION SYSTEM CAN Communication System
A -- Continue to next step.

2. INSPECT PARK / NEUTRAL POSITION SWITCH ASSEMBLY

(a) Disconnect the D35 switch connector.





(b) Measure the resistance of the park / neutral position switch when the shift lever is moved to each position.

Standard Resistance:





NG -- REPLACE PARK / NEUTRAL POSITION SWITCH ASSEMBLY
OK -- Continue to next step.

3. CHECK PARK / NEUTRAL POSITION SWITCH ASSEMBLY (POWER SOURCE)

(a) Disconnect the D35 switch connector.





(b) Measure the voltage according to the value(s) in the table below.

Standard Voltage:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (PARK / NEUTRAL POSITION SWITCH - IGNITION SWITCH)
OK -- Continue to next step.

4. CHECK HARNESS AND CONNECTOR (PARK / NEUTRAL POSITION SWITCH - ECM)

(a) Disconnect the D74 ECM connector.





(b) Measure the voltage according to the value(s) in the table below.

Standard Voltage:





HINT
*: The voltage will drop slightly due to the turning on of the back up light.

Result





E -- REPLACE ECM Removal

D -- REPLACE ECM Removal

C -- REPLACE ECM Removal

B -- REPLACE ECM Removal

A -- REPAIR OR REPLACE HARNESS OR CONNECTOR
