When the seat motor is activated (sensor supply voltage is switched on whenever motor is activated).

SET CONDITION
If during motor operation the sensor voltage is not within a specified range this code will set. This DTC will only set when the seat switch is moved in the same direction three consecutive times.

POSSIBLE CAUSES
- (G403) driver seat recliner position sense circuit shorted to voltage
- Driver recliner seat adjuster motor
- Memory seat module

DIAGNOSTIC TEST

1. TEST FOR INTERMITTENT CONDITION
Turn the ignition on.
With the scan tool, record and erase DTC's
Move the seat switch recliner position 3 times.

With the scan tool erase DTC's
Move the seat switch in the both recliner positions 3 times.
With the scan tool, read DTC's.
