Possible Causes

(G402) DRIVER SEAT REAR VERTICAL POSITION SENSE CIRCUIT SHORTED TO VOLTAGE

REAR DRIVER VERTICAL SEAT ADJUSTER MOTOR

MEMORY SEAT MODULE

1.TEST FOR INTERMITTENT CONDITION

Does the scan tool display B1D76–SEAT REAR VERTICAL POSITION SENSOR CIRCUIT HIGH?

Yes

The conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
Perform POWER SEAT SYSTEM VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/POWER SEATS - DIAGNOSIS AND TESTING)

2.CHECK THE (G402) DRIVER SEAT REAR VERTICAL POSITION SENSE VOLTAGE

NOTE: Check connectors – Clean and repair as necessary.

Does the same DTC reset?

No

Inspect the position sense wire for a possible intermittent short to voltage from another circuit, if OK replace the Rear Driver Vertical Seat Adjuster Motor assembly.
Perform POWER SEAT SYSTEM VERIFICATION TEST – VER 1 (Refer to 8 - ELECTRICAL/POWER SEATS - DIAGNOSIS AND TESTING)

Yes

Inspect the position sense wire for a possible short to voltage from another circuit, if OK replace the Memory Seat Module.
