Affected Component: ENGINE AND ENGINE COOLING
- Summary
- 43880 02 - Service Update Bulletin (Warranty Information section revised). On some vehicles equipped with a start/stop engine control option, the system level interactions related to the transition of run/crank and accessory inputs to the engine control module (ECM) during a crank event are compromised. This results in communication issues between the ECM and the intelligent battery sensor. The check engine light will illuminate and the stop/start system is suspended while the fault is active, resulting in degraded fuel economy.
