Normal Operation
The left rear heated seat module receives battery voltage feed on circuit 1445 (RD/LG) and ignition voltage feed on circuit 1040 (RD/BK), and is supplied ground on circuit 57 (BK). 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/PK) to command the system ON or OFF (HIGH heat mode).

Possible Causes
A left rear 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.
