- Ignition OFF, disconnect the X1 and X4 harness connectors at the K40 Seat Memory Control Module.
- Test for infinite resistance between the control circuit terminal 6 X1 and ground.
- If not the specified value, test the control circuits listed below for a short to ground:
- Driver seat cushion and back element terminal 6 X1
- Driver seat cushion element terminal 11 X1
- Driver seat back element terminal 1 X1
- Test for infinite resistance between the control circuit terminal 14 X1 and ground.
- If not the specified value, test the control circuits listed below for a short to ground:
- Passenger seat cushion and back element terminal 14 X1
- Passenger seat cushion element terminal 14 X4
- Passenger seat back element terminal 4 X1
- Ignition ON, verify that a test lamp does not illuminate between the control circuit terminal 6 X1 and ground.
- If the test lamp illuminates, test the control circuits listed below for a short to voltage:
- Driver seat cushion and back element terminal 6 X1
- Driver seat cushion element terminal 11 X1
- Driver seat back element terminal 1 X1
- Ignition ON, verify that a test lamp does not illuminate between the control circuit terminal 14 X1 and ground.
- If the test lamp illuminates, test the control circuits listed below for a short to voltage:
- Passenger seat cushion and back element terminal 14 X1
- Passenger seat cushion element terminal 14 X4
- Passenger seat back element terminal 4 X1
- If all circuits test normal, replace the K40 Seat Memory Control Module.
