1. Ignition OFF, disconnect the X2, X5 harness connectors at the MSM.
2. Test for 850 Ohms - 300 kOhms between the signal circuit terminal 2 X5 and the low reference circuit terminal 6 X2.
瀚慖f less than the specified range, test for a short between the signal and low reference circuits. If the circuits test normal, replace the seat
cushion heater element/temperature sensor.
瀚慖f greater than the specified range, test the signal and low reference circuits for a short to voltage or an open/high resistance. If the circuits
test normal, replace the seat cushion heater element/temperature sensor.
3. Connect the X2, X5 harness connectors at the MSM.
4. Disconnect the harness connector at the seat cushion heater element/temperature sensor.
5. 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 MSM.
瀚慖f greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the MSM.
6. If all circuits test normal, replace the MSM.
