Note: Element resistance must be measured twice to ensure that all failure conditions are simulated. First with the seat unoccupied, then with



the seat occupied.



6. Test for 1 - 7 Ohms between control circuit terminal 10 and control circuit terminal 4.



瀚慖f less than the specified range, test for a short between the control circuits. If the circuits test normal, replace the E14D seat cushion



heating element.



瀚慖f greater than the specified range, test the control circuits for an open/high resistance. If the circuits test normal, replace the E14D seat



cushion heating element.



7. If all circuits test normal, replace the K40 seat memory control module.
