DTC B1335 00 or B1335 0B

1. Ignition ON, use a scan tool to clear the current and history diagnostic trouble code.

2. Determine which motor set this DTC by operating the motors listed below one at a time in both directions. Check for the DTC to set between

each motor test.

* Driver seat front vertical motor

* Driver seat rear vertical motor

* Driver seat horizontal motor

* Driver seat recline motor

* Driver seat lumbar horizontal motor

* Driver seat lumbar vertical motor

* Adjustable pedal motor

3. Clear the diagnostic trouble codes.

4. Ignition OFF, disconnect the X1 harness connector at the appropriate seat adjuster assembly, lumbar adjuster assembly, or the adjustable

pedal motor for which the DTC set.

5. Ignition ON, operate the motor adjuster switch in both directions. DTC B1335 00 or B1335 0B should not set.

瀚慖f the DTC sets, test for a short between appropriate motor control circuits listed below. If the circuits test normal, replace the MSM.

* Front vertical motor terminal 2 and terminal 5

* Rear vertical motor terminal 1 and terminal 4

* Seat horizontal motor terminal 3 and terminal 6

* Seat recline motor terminal A and terminal B

* Lumbar vertical motor terminal A and terminal B

* Lumbar horizontal motor terminal C and terminal D

* Adjustable pedal motor terminal 4 and terminal 5

6. Test the appropriate control circuits listed below for a high resistance. If all circuits test normal, test or replace the appropriate seat, lumbar,

or adjustable pedal motor.

* Front vertical motor terminal 2 and terminal 5

* Rear vertical motor terminal 1 and terminal 4

* Seat horizontal motor terminal 3 and terminal 6

* Seat recline motor terminal A and terminal B

* Lumbar vertical motor terminal A and terminal B
