Circuit/System Testing

  1. Ignition OFF, disconnect the X5 in-line harness connector at the K32 Heated Steering Wheel Control Module.
  2. Test for less than 10 Ω between the ground circuit terminal 2 and ground.
    • If 10 Ω or greater 
    1. Ignition OFF.
    2. Test for less than 2 Ω in the ground circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, repair the open/high resistance in the ground connection.
    • If less than 10 Ω 
  3. Ignition ON.
  4. Verify a test lamp illuminates between the ignition voltage circuit terminal 1 and ground.
    • If the test lamp does not illuminate and the circuit fuse is good 
    1. Ignition OFF, remove the test lamp.
    2. Test for less than 2 Ω in the ignition circuit end to end.
      • If less than 2 Ω, verify the fuse is OK and there is voltage at the fuse. Refer to Power Mode Mismatch .
      • If 2 Ω or greater
    3. Verify the in-line fuse is OK and there is voltage at the fuse.
      • If the in-line fuse is blown, replace the K32 Steering Wheel Heating Control Module.
      • If the in-line fuse is OK, repair the open/high resistance in the circuit.
    • If the test lamp does not illuminate and the circuit fuse is open 
    1. Ignition OFF.
    2. Test for infinite resistance between the ignition voltage circuit and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance, replace the K32 Steering Wheel Heating Control Module.
    • If the test lamp illuminates 
  5. Ignition OFF, connect the X5 in-line harness connector. Disconnect the harness connector at the S70L Steering Wheel Controls Switch - Left.
  6. Test for less than 10 Ω between the ground terminal 8 and ground.
    • If 10 Ω or greater 
    1. Ignition OFF.
    2. Test for less than 2 Ω in the ground circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, repair the open/high resistance in the ground connection.
    • If less than 10 Ω 
  7. Connect the harness connector at the S70L Steering Wheel Controls Switch - Left.
  8. Disconnect the in-line connector at the S70L Steering Wheel Controls Switch - Left.
  9. Install a 3A fused jumper wire between the indicator control circuit terminal 2 and B+.
  10. Verify the heated steering wheel indicator is illuminated.
    • If the indicator does not illuminate 

      Replace the S70L Steering Wheel Controls Switch - Left.

    • If the indicator illuminates 
  11. Replace the K32 Steering Wheel Heating Control Module.
