Pinpoint Test A: Seat SWITCHPACK Tests

WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
  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 article of the repair 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 electrical circuit diagrams and check seat switchpack ground circuit for open circuit, high resistance. Repair the harness as necessary

      No 

      Refer to the electrical circuit diagrams and check seat switchpack power circuit for open circuit, high resistance. Repair the harness as necessary
