Pinpoint Test J: The Climate Controlled Seat Module Does Not Respond To The Diagnostic Tool

WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Use the correct probe adaptor(s) when making measurements. Failure to use the correct probe adaptor(s) may damage the connector.

J1 CHECK THE CLIMATE CONTROLLED SEAT MODULE C3305C FOR DAMAGE
- Key in OFF position.
- Disconnect: Climate Controlled Seat Module C3305c.
- Inspect the climate controlled seat module C3305c for damage.
- Is the climate controlled seat module C3305c OK?
Yes : GO to J2.

No : REPAIR the climate controlled seat module C3305c as necessary. CONNECT the climate controlled seat module C3305c. CARRY OUT the data link diagnostics test.
J2 CHECK THE MEDIUM SPEED CAN CIRCUITS BETWEEN THE DLC AND THE CLIMATE CONTROLLED SEAT MODULE FOR AN OPEN
- Measure the resistance between the climate controlled seat module C3305c-1, circuit VDB06 (GY/OG), harness side and the DLC C251-3, circuit VDB06 (GY/OG), harness side.

- Are the resistances less than 5 ohms?
Yes : GO to J3.

No : REPAIR the circuit. CONNECT the climate controlled seat module C3305c. CARRY OUT the data link diagnostics test.
J3 CHECK FOR CORRECT CLIMATE CONTROLLED SEAT MODULE OPERATION
- Disconnect all the climate controlled seat module connectors.
- Check for:
  - Corrosion
  - Pushed-out pins
- Connect all the 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 climate controlled seat module. REFER to SEATING . CLEAR the diagnostic trouble codes (DTCs). REPEAT the self-test. CARRY OUT the data link diagnostics test.

No : The system is operating correctly at this time. The 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.
