Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the adjustable pedal motor.
  2. Ignition OFF, test for less than 1.0 ohm of resistance between the low reference circuit terminal 3 and ground.
    • If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the memory seat module.
  3. Ignition ON, test for 4.8-5.2 volts between the 5-volt reference circuit terminal 1 and ground.
    • If less than the specified range, test the 5-volt reference circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the memory seat module.
    • If greater than the specified range, test the 5-volt reference circuit for a short to voltage. If the circuit tests normal, replace the memory seat module.
  4. Verify the scan tool pedal position parameter is less than 0.45 volt.
    • If greater than the specified range, test the signal circuit terminal 2 for a short to voltage. If the circuit tests normal, replace the memory seat module.
  5. Install a 3-amp fused jumper wire between the signal circuit terminal 2 and the 5-volt reference circuit terminal 1. Verify the scan tool pedal position parameter is greater than 4.55 volts.
    • If less than the specified range, test the signal circuit for short to ground or an open/high resistance. If the circuit tests normal, replace the memory seat module.
  6. If all circuits test normal, test or replace the adjustable pedal motor.
