Circuit/System Testing

  1. Vehicle OFF, disconnect the connector at the S13 Door lock switch.
  2. Test for less than 10 Ω between the low reference circuit terminal 5 and ground.
    • If 10 Ω or greater 
    1. Test circuit 3151 for an open/high resistance.
      • If an open/high resistance is found, repair the fault on the circuit.
      • Go to next step: If an open/high resistance is not found
    2. Repair the open/high resistance in the ground connection.
    • Go to next step: If less than 10 Ω 
  3. Vehicle in Service Mode.
  4. Press a power seat switch, to wake up the K40D Driver Seat Adjuster Memory Module.
  5. Test for 9 V or greater between signal circuit terminal 6 and ground.
    • If less than 9 V 
    1. Test circuit 614 for a short to ground.
      • If a short to ground is found, repair the fault on the circuit.
      • Go to next step: If a short to ground is not found
    2. Test circuit 614 for an open/high resistance.
      • If an open/high resistance is found, repair the fault on the circuit.
      • Go to next step: If an open/high resistance is not found
    3. Replace the K40D Driver Seat Adjuster Memory Module.
    • Go to next step: If 9 V or greater 
  6. Test for 4.8 - 5.2 Volts between signal circuit terminal 7 and ground.
    • If less than 4.8 V 
    1. Test circuit 615 for a short to ground.
      • If a short to ground is found, repair the fault on the circuit.
      • Go to next step: If a short to ground is not found
    2. Test circuit 615 for an open/high resistance.
      • If an open/high resistance is found, repair the fault on the circuit.
      • Go to next step: If an open/high resistance is not found
    3. Replace the K40D Driver Seat Adjuster Memory Module.
    • If greater than 5.2 V 
    1. Test circuit 615 for a short to voltage.
      • If a short to voltage is found, repair the fault on the circuit.
      • Go to next step: If a short to voltage is not found
    2. Replace the K40D Driver Seat Adjuster Memory Module.
    • Go to next step: If between 4.8 - 5.2 V 
  7. Vehicle OFF, disconnect the connector X3 at the K40D Driver Seat Adjuster Memory Module.
  8. Vehicle in Service Mode.
  9. Test for less than 1 V between signal circuit terminal 6 and ground.
    • If 1 V or greater 

      Repair the short to voltage on the circuit 614.

    • Go to next step: If less than 1 V 
  10. Test or replace the S13 Door lock switch.
