Circuit Description
The steering column module determines the telescoping position of the steering column based on the following factors:
| • | Inputs received from the telescope position sensor that is built into the telescope actuator |
| • | The telescoping actuator |
The steering column module supplies a 5-volt reference and a ground to the telescoping position sensor, while also monitoring the column position from the telescope position signal circuit.
DTC Descriptor
This diagnostic procedure supports the following DTC:
DTC B2862 Telescope Position Sensor Low
Conditions for Running the DTC
DTC B1327 is not set as current.
Conditions for Setting the DTC
This DTC sets as current when the voltage at the steering column telescope motor signal is less than 0.12 volts for 2 seconds on the telescoping circuit.
Action Taken When the DTC Sets
The steering column module will not allow the affected motor to work during memory recall or easy exit operations. However, the motor will still operate during manual switch positioning.
Conditions for Clearing the DTC
This DTC will clear from current status when the voltage is greater than 0.12 volts for 2 seconds.
