FAQ for Seat Heater Pad Repair
Q: What should be cautioned about the Heated/Cooled Seats Inoperative (X88 or Z88)?
A:
If the test lamp does not illuminate, you should test the signal circuit for a short to voltage or open/high resistance. If the circuit tests normal, you should replace the MSM. If the test lamp remains ON with the switch in the OFF position, you need to test the signal circuit for a short to ground. If the circuit tests normal, you should replace the MSM. If the resistance is measured with the seat still warm or cool, the resistance values will vary. At 20, the nominal resistance value is 1200 Ohms±5 percent. For warmer or cooler ambient temperatures, refer to the Temperature vs Resistance table below. The delta resistance values between the seat cushion and seat back temperature sensors should not be greater than 2000 Ohms.

01/11/2022Q: How to test the circuit system of Heated/Cooled Seats Inoperative (X88 or Z88)?
A:
With ignition OFF, you should disconnect the X1 harness connector at the CCSM, and verify that a test lamp illuminates between the ground circuit terminal M and B+. If the test lamp does not illuminate, you should test the ground circuit for an open/high resistance. Then you should verify that a test lamp illuminates between the B+ circuit terminal E and ground, disconnect the X2 harness connector at the CCSM, and with ignition ON, verify that a test lamp illuminates between the ignition circuit terminal 1 and ground. If the test lamp does not illuminate, you should test the ignition circuit for a short to ground or open/high resistance. If all circuits test normal, you should replace the CCSM.

01/11/2022Q: How to verify the Circuit/System?
A:
You should engine running, and observe the scan tool Rear HVAC/RSA parameters listed below while pressing and releasing the appropriate heated seat switch. The reading should change between Inactive and Active and the appropriate switch indicators should illuminate. If not the specified values, you should replace the auxiliary heater and air conditioning control module. If the scan tool parameters test normal, but, the switch indicators do not illuminate, you should replace the auxiliary heater and air conditioning control module. If all scan tool parameters test normal and there are no DTCs set, you should replace the RHSM.

01/11/2022Q: What should we know about the Circuit/System?
A:
The driver and front passenger heated seats are controlled by separate heated seat switches located on the door panels. When a heated seat switch is pressed, the ground is momentarily applied through the switch contacts and the switch signal circuit to the door lock/window switch. In response to this signal, the door lock/window switch sends a serial message to the memory seat module (MSM) or heated seat module (HSM) indicating the heat seat request. The module then applied battery voltage to the seat cushion and seat back heater elements through a common voltage supply circuit. Each heater element is grounded by the module through separate low-side drive control circuits. The heater element control circuits are pulse width modulated (PWM) to the ground by the module to control the seat temperatures by regulating the current flow through the heater elements. The MSM/HSM relies on 4 independent inputs from temperature sensors (thermistors) located in the seat back and seat cushion of the driver and passenger seats. The temperature sensor resistance varies based on the temperature of the heating element causing the signal circuit voltage to change. Once the seat reaches the switch set temperature, the MSM/HSM will then cycle the control circuits of the heating elements ON and OFF to maintain the desired seat temperature based on the feedback voltage from the sensors. The MSM/HSM then monitors the current flow through the heating elements and the rate change of the temperature sensor to verify the correct heated seat operation.
