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

unoccupied, then with the seat occupied.

2. Test for 2.0 - 8.0 Ohms between control circuit terminal 6 and control circuit terminal 2.

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

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 seat cushion

heater element.

3. Disconnect the X2, X4 harness connectors at the HSM.

4. Test for 850 Ohms - 300 kOhms between the signal circuit terminal 20 X4 and the low reference circuit terminal 8 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.

5. Connect the X1, X2, X4 harness connectors at the HSM.

6. Disconnect the harness connector at the seat cushion heater element/temperature sensor.

7. 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 HSM.

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

8. If all circuits test normal, replace the HSM.
