| Condition | Some customers may comment on either a Service Leveling or Service Headlight message displayed on the DIC. When checking for DTC's a U0132 for loss of communication with the K5 Automatic Level Control Module (ALCM) may be set in several modules. When trying to communicate with the Automatic Level Control Module there will be no communication. Also, there could be a complaint of a low or dead battery condition. |
| Cause | This concern could be caused by the K5 Automatic Level Control Module calibration. |
CORRECTION

- Turn the ignition off
- Open the hood and access the X50A Engine Wiring Harness Junction block, located near the battery.
- Find and remove fuses 61 (15 amp) and 68 (40 amp).
- Leave the fuses removed for several minutes and then reinstall.
- Turn ignition on and check to make sure the ALCM is now communicating.
- If communication returns, then reprogram the K5 Automatic Level Control Module with the latest calibrations available in Tis2Web.
- If communication does not return, then perform normal SI diagnostics.IMPORTANT:
To avoid warranty transaction rejections, you MUST record the warranty claim code provided on the Warranty Claim Code (WCC)screen at the end of the SPS programming event.
