Circuit/System Verification
1. Ignition ON, observe the appropriate scan tool driver or passenger Seat Heat Mode Sw. parameter while pressing and releasing the appropriate
heated seat switch. The readings should change between Inactive and Active.
‹› If not the specified value, refer to Heated and Cooled Seat Switch Malfunction.
2. If the heated seat switch function operates OK, but, one or more of the heated seat switch indicators is inoperative or is always ON, refer to Heated
and Cooled Seat Switch Indicator Malfunction.
3. If all scan tool parameters test normal and there are no DTCs set, replace the MSM.
Circuit/System Testing
Heated and Cooled Seat Switch Malfunction
1. Ignition OFF, disconnect the harness connector at the appropriate heated and cooled seat switch.
2. Ignition OFF, test for less than 10 Ohms between the ground circuit terminal 7 and ground.
‹› If greater than the specified range, test the ground circuit for an open/high resistance.
3. Ignition ON, verify the scan tool Seat Heat Mode Sw. parameter is Inactive.
‹› If not the specified value, test the signal circuit terminal 4 for a short to ground. If the circuit tests normal, replace the appropriate driver or
passenger door module.
4. Install a 3 A fused jumper wire between the signal circuit terminal 4 and ground. Verify the scan tool Seat Heat Mode Sw. parameter is Active.
‹› If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the
appropriate driver or passenger door module.
5. If all circuits test normal, test or replace the heated and cooled seat switch.
Heated and Cooled Seat Switch Indicator Malfunction
1. Ignition OFF, disconnect the harness connector at the appropriate heated and cooled seat switch.
2. Ignition ON, connect a test lamp between the control circuits listed below and ground. Command the appropriate driver or passenger door switch
Heated Seat Indicator ON and OFF with a scan tool. The test lamp should turn ON and OFF when changing between the commanded states.
*
Back and cushion heat indicator terminal 1
*
Low heat indicator terminal 6
*
Medium heat indicator terminal 8
*
High heat indicator terminal 10
‹› If the test lamp is always ON, test the appropriate control circuit for a short to voltage. If the circuit tests normal, replace the door module.
‹› If the test lamp is always OFF, test the appropriate control circuit for a short to ground or an open/high resistance. If the circuit tests normal,
replace the door module.
3. If all circuits test normal, test or replace the heated and cooled seat switch.
Component Testing
Heated Seat Switch
1. Ignition OFF, disconnect the harness connector at the heated and cooled seat switch switch.
2. Test for infinite resistance between the signal terminal 4 and the ground terminal 7 with the back/cushion switch in the open position.
‹› If not the specified value, replace the heated and cooled seat switch switch.
3. Test for infinite resistance between the signal terminal 5 and the ground terminal 7 with the cool mode switch in the open position.
