Heated Seat Module

  1. If a heated seat fails to heat and one or both of the LED indicator lamps on a heated seat switch flash, see HEATED SEAT SYSTEM TROUBLE SHOOTING  under TROUBLE SHOOTING.
  2. Test the appropriate heated seat switch, see HEATED SEAT SWITCH  .
  3. Test the heated seat sensor, see HEATED SEAT SENSOR  .
  4. Test the heated seat element, see HEATED SEAT ELEMENT  .
  5. Disconnect the heated seat module connector receptacle. Using an ohmmeter, check for continuity between the ground circuit cavity and a good ground. If OK, go to next step. If not OK, repair the open ground circuit to ground as required.
  6. Disconnect the heated seat module connector receptacle. Using an voltmeter, check for voltage on the B+ circuit cavity. If OK, go to next step. If not OK, repair the open B+ circuit as required.
  7. Replace the heated seat module with a known-good module. See HEATED SEAT MODULE  under REMOVAL & INSTALLATION. Test operation of the heated seat system. If system works, repair is complete. If system is still inoperative a short or open exists in the heated seat system wiring. Using wiring diagrams as a guide, check the individual circuits until the short or open is found.
