- Ignition OFF, disconnect the X2 and X3 harness connectors at the K29 Seat Heating Control Module.
- Test for greater than 3.0 kΩ between the signal and the low reference circuit terminals listed below:
- Driver seat cushion terminal 3 X3 and terminal 13 X2
- Passenger seat cushion terminal 4 X3 and terminal 14 X2
- Ignition OFF, disconnect the harness connector at the appropriate E14B or E14D Seat Heating Element - Cushion.
- Test for Infinite resistance between the signal and low reference circuits.
- If less than infinite resistance, repair the short between the circuits.
- If infinite resistance, test or replace the E14 Seat Heating Element - Cushion.
- Replace the K29 Seat Heating Control Module.
