For wiring diagrams, refer to Memory Seats Schematics (Seat Adjuster Memory Module, Trandsucers, Motors).

Diagnostic Chart:

CIRCUIT DESCRIPTION
The seat adjuster memory module monitors the seat lateral motor position through the seat lateral transducer CKT 569 (DK GRN). The seat adjuster memory module also sends a reference voltage on CKT 569 (RED) to CKT 569B (RED) and provides a sensor ground, CKT 569 (BLK) to CKT 569A (BLK).

CONDITIONS FOR SETTING THE DTC
The DTC will set if the seat adjuster memory module detects that the seat rear height sensor output voltage is either too high or too low due to the following conditions:
^ An open circuit
^ A short to ground
^ A short to power
^ A defective seat height transducer

CONDITIONS FOR CLEARING THE DTC
^ A history DTC will clear after 100 consecutive fault free ignition cycles.
^ Use a scan tool in order to clear history and current DTCs.

DIAGNOSTIC AIDS
One or more of the following conditions may be the cause of an intermittent failure:
^ A poor connection
^ A break in the wire insulation that exposes the internal wire
^ A wire broken inside the insulation

TEST DESCRIPTION
The numbers below refer to the step numbers on the diagnostic table.
2. This step inspects for current DTCs.
3. This step locates and repairs open(s) in the wiring between the seat lateral transducer and the seat adjuster memory module.
4. This step locates and repairs short(s) to ground in the wiring between the seat lateral transducer and the seat adjuster memory module.
5. This step verifies that the seat adjuster memory module is supplying the reference voltage to the seat lateral transducer.
6. This step replaces a defective seat lateral transducer.
7. This step replaces a defective seat adjuster memory module.
