Test P: The Heated Seat Does Not Operate Correctly - Driver Seat Does Heat But The Heated Seat Indicator Does Not Illuminate

PINPOINT TEST P: THE HEATED SEAT DOES NOT OPERATE CORRECTLY - DRIVER SEAT DOES HEAT BUT THE HEATED SEAT INDICATOR DOES NOT ILLUMINATE

Normal Operation
Upon receiving a signal from heating ventilation and air-conditioning (HVAC) module, the heated seat module will decrease one setting (the sequence is high, low, off, high, etc.). Circuits CHS04 (YE/GY) and CHS13 (VT/BN) between the heated seat module and HVAC supply the control signals for the indicators to operate. When a heated seat is set to high, both LED indicators above the heated seat control button will illuminate. When a heated seat is set to low, only the left LED indicator will illuminate. When a heated seat is set to off, neither LED will be illuminated.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Heated seat module
- HVAC
