Conditions for Clearing the DTC



* The current DTC will clear and set the code to history 3 seconds after the reference voltage returns to normal operating range and the ignition



is cycled OFF then back to ACC or RUN.



* The history DTC will clear after 40 consecutive fault-free ignition cycles have occurred.

Circuit/System Testing



1. Ignition OFF, disconnect the harness connector at the appropriate E14B or E14D seat cushion heating element.



2. Test for less than 10 Ohms between the low reference circuit terminal D and ground.



瀚慖f greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit test normal, replace the K29 seat



heating control module.



3. Ignition ON, test for 4.8 - 5.2 V between the signal circuit terminal C and ground.



瀚慖f less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace



the K29 seat heating control module.



瀚慖f greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the K29 seat heating



control module.



4. If all circuits test normal, test or replace the E14 seat cushion heating element.



Component Testing



E14B or E14D Seat Cushion Heating Element



1. Ignition OFF, disconnect the harness connector at the appropriate E14B or E14D seat cushion heating element.



2. Test for 500 Ohms - 300 kOhms between the signal circuit terminal C and the low reference circuit terminal D.



瀚慖f not within the specified range, replace the E14 seat cushion heating element.



Repair Instructions



Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.



* Driver or Passenger Seat Cushion Heater Replacement (See: Body and Frame/Seats/Seat Temperature Element/Service and Repair/Driver or



Passenger Seat Cushion Heater Replacement)
