Action Taken When DTC Sets

WARNING: This page is about a different car, the 2003 Cadillac Seville and 2003 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.

The PCM does not illuminate the Malfunction Indicator Lamp (MIL).
SERVICE ELECTRICAL SYSTEM displays on the Driver Information Center (DIC).
The PCM disregards the TCC brake switch for TCC scheduling. The PCM then uses throttle position and vehicle speed inputs to determine TCC application and release. Use of these inputs may result in a noticeable harsh apply or abrupt release of the TCC.
The PCM records the operating conditions when the Conditions For Setting DTC are met. The PCM stores this information as Failure Records.
The PCM stores DTC P0719 in PCM history.
