Normal Operation
The driver heated seat module receives battery voltage feed on circuit 1048 (LB/WH) and ignition voltage feed on circuit 1040 (RD/BK), and is supplied ground on circuit 676 (PK/OG). When the heated seat control switch is pressed with the ignition switch in RUN or START, a ground signal is sent to the heated seat module on circuit 1020 (DG/VT) to command the system ON or OFF in HI heat mode.

Possible Causes
A driver heated seat that does not operate in HI can be caused by:
- faulty wiring, terminals or connectors.
- a faulty heated seat switch.
- a faulty heated seat module.
