Circuit Description
The steering column module provides a 5-volt reference voltage to the tilt position sensor circuit and to the telescope position sensor circuit. The steering column module monitors the 5-volt reference voltage and sets DTC B1396, if the voltage is out of range.
DTC Descriptor
This diagnostic procedure supports the following DTC:
DTC B1396 Device Voltage Reference Output Circuit Range/Performance
Conditions for Running the DTC
The steering column module is ON.
Conditions for Setting the DTC
DTC B1396 will set as current when the voltage is out of the range of 4.6-5.2 volts for 1.2 seconds.
Action Taken When the DTC Sets
Memory recall functions for the steering column module will be disabled.
Conditions for Clearing the DTC
| • | DTC B1396 will no longer have a current status when the voltage is within the range of 4.6-5.2 volts for 1.2 seconds. |
| • | A scan tool can clear the DTC. |
Diagnostic Aids
A short to ground in any of the tilt or telescope position sensor circuits may damage the tilt/telescoping module.
