Pinpoint Test D: B2340, B2341: Notes
B2340, B2341
Refer to Adjustable Steering Column for schematic and connector information.
Normal Operation and Fault Conditions
To protect the power tilt and telescopic motors, motor circuits and the electronics internal to the DSM, the DSM continually monitors both motors for a stall condition whenever the motors are activated. If the one or both motors stop moving unexpectedly for at least one-quarter of a second, the DSM stops applying power to the motors until the next time it receives a command to move the motor. If this condition is detected during a DSM on-demand self test of the DSM, a power tilt or power telescopic motor stall DTC is set.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B2340 | Column Reach Motor Stalled | This DTC sets on-demand if the telescopic motor does not move when commanded. Output to the motor is disabled if the stall lasts longer than one-quarter of a second. |
| B2341 | Column Tilt Motor Stalled | This DTC sets on-demand if the tilt motor does not move when commanded. Output to the motor is disabled if the stall lasts longer than one-quarter of a second. |
