Pinpoint Test W: The Heated Seat Does Not Operate Correctly - Right Rear Heated Seat Indicator is Always On

Normal Operation

With the ignition and heated seat on, the heated seat module supplies voltage to the indicator circuit(s) to illuminate the appropriate switch indicator. The heated seat and indicator deactivates with a second button press.

A new heated seat module must be configured after installation for correct operation. To configure, press the low heat mode button on either rear heated seat switch. Module configuration will occur automatically after the low heat mode button is pressed. Until the module is correctly configured, the heated seats will operate incorrectly when selecting the high heat mode by following a sequence of high, low and off with each button press. The system will operate correctly after the heated seat module receives a low heat request on either of the low heat request circuits and rear heated seat module configuration is activated.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors

- Heated seat module
