WARNING: This page is about a different car, the 2004 Mercury Monterey and 2004 Ford Freestar. However, it is still accessible from the selected car via links, so may be relevant.

J1 CHECK THE UBP NETWORK CIRCUIT BETWEEN THE CLIMATE CONTROLLED SEAT MODULE AND THE DLC FOR AN OPEN
- Key in OFF position.
- Disconnect: Driver Climate Controlled Seat Module C3031a, or the Passenger Climate Controlled Seat Module C3036a.
- Measure the resistance between the driver climate controlled seat module C3031a-A, or passenger climate controlled seat module C3036a-A, circuit 2077 (PK/LB), harness side and the DLC C251-3, circuit 2077 (PK/LB), harness side.

- Are the resistances less than 5 ohms?
Yes

GO to J2

No

REPAIR the circuit in question. CLEAR the DTCs. REPEAT the self-test. CARRY OUT the data link diagnostics test.
J2 CHECK FOR CORRECT CLIMATE CONTROLLED SEAT MODULE OPERATION
- Disconnect all the driver or passenger climate controlled seat module connectors.
- Check for:
  - corrosion
  - push-out pins
- Connect all the driver or passenger climate controlled seat module connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
Yes

INSTALL a new driver or passenger climate controlled seat module. Refer to SEATING . CLEAR the DTCs. REPEAT the self-test. CARRY OUT the data link diagnostics test.

No

The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test. CARRY OUT the data link diagnostics test.
