Heated Seat Module Reset

NOTE: This heated seat module is used on 2 different systems. These systems use 2 different on/off switches, the single momentary switch and the dual momentary switch. A new heated seat module is programmed to function for a single momentary switch.

The single momentary switch provides a ground signal to the heated seat module on one circuit. This cycles the system high, low and off.

The dual momentary switch provides a ground to the heated seat module on 2 different circuits. Toggling the dual momentary switch to one side cycles the system low and off. Toggling the switch to the other side cycles the system high and off.

When a new heated seat module is installed on a system with a dual momentary switch and the module receives a ground signal from the low circuit of that switch, the module is then programmed to function for a dual momentary switch. Now the heated seat module will expect to see ground signals on 2 different circuits to cycle the system high/off and low/off.

Once the heated seat module is programmed for use with dual momentary switches, the heated seat module cannot be used with a single momentary switch heated seat system until the following reset procedure is carried out.

Back probe and short both high switch inputs to ground.

Turn the ignition ON.
Wait for heated seat switch LEDs to start flashing.
Disconnect both grounds as soon as the heated seat switch LEDs start flashing.
The LEDs will flash a total of 5 times when the module is reset.
- Wait for the LEDs to stop flashing and the system should work correctly.
If the system does not work correctly, carry out the Heated Seat Module Reset steps again. Otherwise, refer to the SYMPTOM CHART in the Seats portion of this section.
