Pinpoint Test : GEAR SELECTOR LEVER ASSEMBLY CIRCUIT CHECKS

Disconnect the gear selector lever assembly electrical connector IP027.

Set the ignition status to ON, engine OFF.

Measure the voltage at IP027 Pin 1.

Is the voltage greater than 10 Volts? 

YES:  Go to step  2.

NO:  Repair the electrical circuit between the gear selector lever assembly electrical connector IP027 Pin 1 and the Central Junction Box (CJB). For additional information, refer to the appropriate system wiring diagrams article. TEST the system for normal operation.

Set the ignition status to OFF.

Measure the resistance between the gear selector lever assembly electrical connector IP027 Pin 2 and GROUND.

Is the resistance less than 5 Ohms? 

YES:  Go to step  3.

NO:  Repair the circuit between the gear selector lever assembly electrical connector IP027 Pin 2 and GROUND. For additional information, refer to the appropriate system wiring diagrams article. TEST the system for normal operation.

Set the ignition status to ON, engine OFF

Measure the voltage at IP027 Pin 4.

Is the voltage greater than 10 Volts? 

YES:  No fault has been identified with the gear selector lever assembly circuits. Check all connections for damaged and corroded pins. Check CAN network using manufacturer approved diagnostic system. TEST the system for normal operation.

NO:  Repair the electrical circuit between the gear selector lever assembly electrical connector IP027 Pin 4 and the Central Junction Box (CJB). For additional information, refer to the appropriate system wiring diagrams article. TEST the system for normal operation.
