B1D6E-SEAT HORIZONTAL POSITION SENSOR CIRCUIT HIGH
For a complete wiring diagram Refer to Section 8W.
- When Monitored:
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 |
| (G401) DRIVER SEAT HORIZONTAL POSITION SENSE CIRCUIT SHORTED TO VOLTAGE |
| DRIVER RECLINER SEAT ADJUSTER MOTOR |
| MEMORY SEAT MODULE |
Diagnostic Test
1. TEST FOR INTERMITTENT CONDITIONTurn the ignition on.
With the scan tool, record and erase DTC's
Move the seat switch in the horizontal position three times.
With the scan tool, read DTC's.
Does the scan tool display B1D6E–SEAT HORIZONTAL POSITION SENSOR CIRCUIT HIGH?
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 - VER 1. (Refer to 8 - ELECTRICAL/POWER SEATS - DIAGNOSIS AND TESTING)
2. CHECK THE (G401) DRIVER SEAT HORIZONTAL POSITION SENSE VOLTAGE
Disconnect the Driver Horizontal Seat Adjuster Motor.
NOTE: Check connectors – Clean and repair as necessary.
With the scan tool erase DTC's
Move the seat switch in the horizontal positions three times.
With the scan tool, read DTC's.
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 Driver Horizontal 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.
- Perform POWER SEAT SYSTEM VERIFICATION TEST – VER 1 (Refer to 8 - ELECTRICAL/POWER SEATS - DIAGNOSIS AND TESTING)
