# Service bulletin A461508 2040449\-

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

Customer may report that Electronic Stability Control \(ESC\) and Tire Pressure Monitoring System \(TPMS\) warnings are intermittently displayed in the instrument cluster. DTCs are stored in the ABS control module. During vehicle start\-up, there may be a drop in voltage that causes the DTCs to be stored in the ABS control module. However, the power steering control module, J500 \(address word 44\), must be updated to correct this condition.
