Pinpoint Test A: Seat SWITCHPACK Tests

WARNING: This page is about a different car, the 2018 Jaguar XE and 2017 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

TEST CONDITIONS 

DETAILS/RESULTS/ACTIONS 

  1. A1: SEAT SWITCHPACK TEST 1 
    1. Check the specification of the seat

    Are there memory functions for the seat?

    • Yes  : GO to A2.
    • No  : GO to  A3.
  2. A2: SEAT SWITCHPACK TEST 2 
    NOTE: Some DTCs can only be set if the fault is detected during the On Demand Self Test routine.
    1. Using the Jaguar Land Rover approved diagnostic equipment, perform routine - On Demand Self Test.
    2. Using the Jaguar Land Rover approved diagnostic equipment, check the relevant seat module for related DTCs and refer to the relevant DTC index.

    Are any relevant DTCs set?

    • Yes  : Perform the relevant corrective action
    • No  : GO to A3.
  3. A3: SEAT SWITCHPACK TEST 3 
    NOTE: Perform this test at every power circuit terminal in the seat switchpack connector.
    1. Set a multimeter to measure voltage
    2. Using the multimeter, measure and record the battery voltage (reference voltage)
      NOTE: Do not disconnect the electrical connector during this step; the seat switchpack is removed for access to the wiring harness only.
    3. Refer to the relevant section of the service information and remove the seat switchpack.
    4. Set the ignition to on
      NOTE: Circuit reference - VBATT/GND -
    5. Connect the multimeter across the seat switchpack power terminal and the ground terminal.

    Is the measured voltage less than battery voltage?

    • Yes  : GO to A4.
    • No  : Install a new seat switchpack.
  4. A4: SEAT SWITCHPACK TEST 4 
    NOTE: Circuit reference - GND -
    1. Connect the multimeter to the seat switchpack ground terminal and battery negative

    Is the measured voltage greater than 0V?

    • Yes  : Refer to the applicable System Wiring Diagram(s) and check seat switchpack ground circuit for open circuit, high resistance. Repair the harness as necessary.
    • No  : Refer to the applicable System Wiring Diagram(s) and check seat switchpack power circuit for open circuit, high resistance. Repair the harness as necessary.
