Circuit/System Testing
1. Ignition OFF, disconnect the X2, X3 harness connectors at the K40 seat memory control module.
2. Test for greater than 3.0 kOhms between the signal and the low reference circuits listed below:
* E14B driver seat cushion terminal 16 X2 and terminal 12 X3
* E14D passenger seat cushion terminal 7 X2 and terminal 1 X3
瀚慖f less than the specified value, test for a short between the signal and low reference circuits. If the circuits test normal, replace the
appropriate E14 seat cushion heating element.
3. If all circuits test normal, replace the K40 seat memory control module.
