Liftgate Calibration

Liftgate Relearn

Note

To ensure proper relearning of the liftgate, the liftgate assembly must be at room temperature during the relearn process.

Note

DTC B1C0A 54 will set automatically as an indicator that the system is in learn mode and not as a fault indicator. Once the travel limits are learned by the liftgate module, the liftgate module will exit learn mode and DTC B1C0A 54 will become a history code. If any portion of the power liftgate assembly is replaced, repaired or disassembled, perform the following liftgate relearn procedure:

1. Vehicle Power Mode » Run/Service Mode.
2. Install a scan tool and access the Service Programming System (SPS).
3. Perform the Service Programming System (SPS).
4. Follow on screen instructions to complete the rear gate learn procedure, the K194 Rear Gate Module should learn the travel limits, exit the calibration mode, and B1C0A 54 will become a history code. Garage Height Calibration If any portion of the power liftgate assembly is replaced, repaired or disassembled it may be necessary to perform the garage height calibration procedure:
5. Ensure that the rotary switch on the overhead console or driver door panel is set to 3/4.
6. Press the liftgate handle switch and allow the liftgate to power open.
7. Stop movement at the desired height by pressing any operation switch.
8. If required, manually move the stopped liftgate to the desired position.

Note

The opening height of the liftgate should be positioned approximately parallel with the roof, the rear gate module will reject the setting if the liftgate is positioned too low.

5. Press and hold the liftgate close switch for at least 3 seconds. The tail lights will flash if the setting has been successfully programmed.
6. Close the liftgate completely using one of the following switches: The rotary switch on the overhead console or driver door panel The liftgate close switch on the liftgate The remote control switch on the keyless entry transmitter
