MHEV Battery And Cables (G2319498): Operation: Notes

The MHEV battery is controlled by the Powertrain Control Module (PCM) through the integrated Battery Energy Control Module (BECM) in the MHEV battery. The PCM communicates with the BECM through the High Speed (HS) Controller Area Network (CAN) power mode zero systems bus. The BECM transmits the MHEV battery state of charge to the PCM.

If there is a fault with the MHEV battery system the PCM sends a message to the IC to do the following:

• Display the red battery warning indicator in the IC.
• Display any related warning messages in the IC message center.
