Pinpoint Test A: P163200 Charging System Fault

WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2015 Jaguar XKR-S, 2015 Jaguar XKR, 2015 Jaguar XK, 2014 Jaguar XKR-S, and 2014 Jaguar XKR. However, it is still accessible from the selected car via links, so may be relevant.
  1. A1: CHECK THE BATTERY VOLTAGE WITH THE ENGINE RUNNING 
    1. Connect a suitable voltmeter across the battery terminals.
    2. Start the engine and allow to idle with no electrical loads applied.
    3. Measure the maximum voltage achieved at the battery after start.

    Is the voltage greater than 13 volts?

    • Yes: GO to  A2.
    • No  : INSTALL a fully charged battery. GO to  A5.
  2. A2: CHECK THE GENERATOR 'S' TERMINAL FOR BATTERY VOLTAGE 
    1. Set ignition status to OFF.
    2. DISCONNECT generator electrical connector PI048.
    3. MEASURE the voltage at generator electrical connector PI048 pin 3.

    Is the voltage greater than 10 volts?

    • Yes: GO to  A5.
    • No: GO to  A3.
  3. A3: CHECK FUSE 5 IN REAR JUNCTION BOX (RJB) 
    1. Check fuse 5 in the RJB.

    Is the fuse OK?

    • Yes  : REPAIR the circuit between the generator electrical connector PI048 pin 3 and fuse 5 in the RJB. CLEAR the DTC, test the system for normal operation.
    • No: GO to  A4.
  4. A4: CHECK THE GENERATOR 'S' TERMINAL FOR SHORT TO GROUND 
    1. MEASURE the resistance between generator electrical connector PI048 pin 3 and ground.

    Is the resistance less than 10, 000 ohms?

    • Yes  : REPAIR the circuit between the generator electrical connector PI048 pin 3 and fuse 5 of the RJB. INSTALL a new fuse, CLEAR the DTC, test the system for normal operation.
    • No  : INSTALL a new fuse, CLEAR the DTC, test the system for normal operation.
  5. A5: CHECK FOR BATTERY VOLTAGE AT THE GENERATOR 'L' TERMINAL 
    1. Set ignition status to OFF.
    2. Disconnect generator electrical connector PI048.
    3. Set ignition status to ON.
    4. Measure the voltage at generator electrical connector PI048 pin 1.

    Is the voltage greater than 10 volts?

    • Yes  : INSTALL a new generator.

      Refer to: Generator (Removal and Installation).

      CLEAR the DTC, test the system for normal operation.

    • No: GO to  A6.
  6. A6: CHECK THE GENERATOR 'L' LINE FOR SHORT TO GROUND 
    1. Set ignition status to OFF.
    2. Disconnect battery.
    3. MEASURE the resistance between the generator electrical connector PI048 pin 1 and ground.

    Is the resistance less than 1, 000 ohms?

    • Yes  : REPAIR the circuit between the generator electrical connector PI048 pin 1 and the Engine Control Module (ECM). CLEAR the DTC, test the system for normal operation.
    • No: GO to  A7.
  7. A7: CHECK THE GENERATOR 'L' LINE FOR SHORT TO POWER 
    1. MEASURE the resistance between the generator electrical connector PI048 pin 1 and battery positive.

    Is the resistance less than 10, 000 ohms?

    • Yes  : REPAIR the circuit between the generator electrical connector PI048 pin 1 and the Engine Control Module (ECM). CLEAR the DTC, test the system for normal operation.
    • No: GO to  A8.
  8. A8: CHECK THE GENERATOR 'L' LINE FOR OPEN CIRCUIT 
    1. Disconnect the ECM electrical connector PI300.
    2. MEASURE the resistance between the generator electrical connector PI048 pin 1and ECM electrical connector PI300 pin 16.

    Is the resistance less than 5 ohms?

    • Yes  : Install a new generator.

      Refer to: Generator (Removal and Installation).

      CLEAR the DTC, test the system for normal operation.

    • No  : REPAIR the circuit between the generator electrical connector PI048 pin 1 and the ECM electrical connector PI300 pin 16.

      CLEAR the DTC, test the system for normal operation.
