B1D6D

B1D6D-SEAT HORIZONTAL POSITION SENSOR CIRCUIT LOW





For a complete wiring diagram, refer to the Wiring Information.

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

- Set Condition:
If sensor voltage is not within a specified range this DTC will set. This DTC will only set when the seat switch is moved in the same direction three consecutive times.





1. TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
2. With the scan tool, record and erase DTC's
3. Move the Seat Switch in the Horizontal position three times.
4. With the scan tool, read DTC's.

Does the scan tool display B1D6D-SEAT HORIZONTAL POSITION SENSOR CIRCUIT LOW?

Yes

- Go To 2

No

- 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. Power Seat System Verification Test.

2. CHECK THE (G401) DRIVER SEAT HORIZONTAL POSITION SENSE VOLTAGE




1. Disconnect the Driver Horizontal Seat Adjuster Motor.

NOTE: Check connectors - Clean and repair as necessary.

2. Move the Seat Switch in the Horizontal position during the next step.
3. Using a 12-volt test light connect one lead to the (G401) Driver Seat Horizontal Position Sense circuit and the other lead to Driver Seat Horizontal Sensor Ground at the Driver Horizontal Seat Adjuster Motor connector.

Does the test light illuminate for approximately two seconds then turn off with the seat switch engaged?

Yes

- Replace the seat track horizontal motor assembly.
- Perform POWER SEAT SYSTEM VERIFICATION TEST. Power Seat System Verification Test.

No

- Go To 3

3. CHECK THE (G401) DRIVER SEAT HORIZONTAL POSITION SENSE WIRE FOR A SHORT TO GROUND




1. Disconnect the Memory Seat Module C3 connector.

NOTE: Check connectors - Clean and repair as necessary.

2. Measure the resistance of the (G401) Driver Seat Horizontal Position Sense wire at the Driver Horizontal Seat Adjuster Motor connector to ground.

Is the resistance below 1000.0 ohm?

Yes

- Repair the (G401) Driver Seat Horizontal Position Sense circuit for a short to ground.
- Perform POWER SEAT SYSTEM VERIFICATION TEST. Power Seat System Verification Test.

No

- Replace the Memory Seat Module.
- Perform POWER SEAT SYSTEM VERIFICATION TEST. Power Seat System Verification Test.
