Pinpoint Test L: The Climate Controlled Seat Module Does Not Respond To The Diagnostic Tool
WARNING: This page is about a different car, the 2005 Lincoln Navigator and 2005 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
- L1 CHECK THE CLIMATE CONTROLLED SEAT MODULE CONNECTOR FOR DAMAGE
- Key in OFF position.
- Disconnect: Climate Controlled Seat Module C3265b.
- Inspect the climate controlled seat module C3265b for damage.
- Is the climate controlled seat module C3265b OK?
- Yes : GO to L2.
- No : REPAIR the climate controlled seat module C3265b. CARRY OUT the data link diagnostics test.
- L2 CHECK CIRCUITS 2180 (WH/BK) AND 2181 (BK/YE) BETWEEN THE CLIMATE CONTROLLED SEAT MODULE C3265B AND THE DATA LINK CONNECTOR (DLC) C251 FOR AN OPEN
- Measure the resistance between the climate controlled seat module C3265b pin 14, circuit 2180 (WH/BK), harness side and the DLC C251 pin 3, circuit 2180 (WH/BK), harness side.
- Measure the resistance between the climate controlled seat module C3265b pin 15, circuit 2181 (BK/YE), harness side and the DLC C251 pin 11, circuit 2181 (BK/YE), harness side.
- Are the resistances less than 5 ohms?
- Yes : GO to L3.
- No : REPAIR the circuit in question. CARRY OUT the data link diagnostics test.
- L3 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.
