Pinpoint Test C: CHECK THE POSITION ALIGNMENT SWITCH CIRCUIT

  1. CHECK THE POSITION ALIGNMENT SWITCH LOGIC GROUND 

    Disconnect the position alignment switch electrical connector, FC105.

    Measure the resistance between FC105, pin 03 (B) and GROUND.

    Is the resistance greater than 5 ohms? 

    YES:  REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. TEST the system for normal operation.

    NO:  Go to step  2.

  2. CHECK THE POSITION ALIGNMENT SWITCH TO LINEAR SWITCH CIRCUIT FOR HIGH RESISTANCE 

    Disconnect the battery negative terminal.

    Disconnect the linear switch module electrical connector, FC100.

    Measure the resistance between FC105, pin 01 (BW) and FC100, pin ) (BW).

    Is the resistance greater than 5 ohms? 

    YES:  REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. TEST the system for normal operation.

    NO:  Go to step  3.

  3. CHECK THE POSITION ALIGNMENT SWITCH TO LINEAR SWITCH CIRCUIT FOR SHORT TO HIGH VOLTAGE 

    Reconnect the battery negative terminal.

    Measure the voltage between FC105, pin 01 (BW) and GROUND.

    Is the voltage greater than 3 volts? 

    YES:  REPAIR the short circuit. For additional information, refer to the wiring diagrams. TEST the system for normal operation.

    NO:  Go to step  4.

  4. CHECK THE POSITION ALIGNMENT SWITCH TO LINEAR SWITCH CIRCUIT FOR SHORT TO GROUND 

    Measure the resistance between FC105, pin 01 (BW) and GROUND.

    Is the resistance less than 10,000 ohms? 

    YES:  REPAIR the short circuit. For additional information, refer to the wiring diagrams. TEST the system for normal operation.

    NO:  INSTALL a new position alignment switch. CLEAR the DTC. TEST the system for normal operation.
