Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the S47D driver seat memory switch.
  2. Test for less than 10 Ω between the low reference circuit terminal 1 and ground.
  3. If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the K40 seat memory control module.
  4. Ignition ON, press a power seat switch in order to wake up the K40 seat memory control module. Test for greater than 9 V between the signal circuit terminal 6 and ground.
  5. If less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K40 seat memory control module.
  6. Test for greater than 9 V between the signal circuit terminal 5 and ground.
