The steering column tilt/telescoping module (TTM) receives inputs from the tilt position sensor during memory recall, memory set, and easy exit functions. The potentiometer in the tilt position sensor varies in resistance as the motor moves the steering column up or down. The TTM receives a variable voltage input depending on the resistance of the potentiometer. During memory set, the TTM records the voltage across the tilt position sensor potentiometer. During memory recall, the TTM moves the tilt motor until the voltage across the potentiometer matches the voltages stored in memory. For the easy exit function, the TTM moves the tilt motor until the voltage matches what the TTM has recorded in memory for the easy exit. During normal operation, the tilt position sensors are checked against out-of-range limits.

When DTC B2880 is set as current, the steering column tilt/telescoping module (TTM) disables the tilt motor during memory recall or easy exit operations. The tilt motor remains enabled for manual positioning.

The numbers below refer to the step numbers on the diagnostic table:

1. Perform the Tilt/Telescoping Steering Column Diagnostic System Check before continuing with the diagnosis of this DTC.

2. Determines whether the failure is in the steering column tilt/telescoping module (TTM) or the tilt position sensor.

5. Clear all DTCs after the repair procedure is complete.
