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 K40 seat
memory control module.
3. Ignition ON, press a power seat switch in order to wake up the module. 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 K40 seat memory 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 K40 seat memory
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.
