MECU Power Supply (V)

The value indicates the actual power supply to the Central Electronic Module (CEM), which in turn sends the information via the CAN to the Electronic Control Module (ECM).

Normal value: 12.2 - 15.5 V (same as battery voltage) when the alternator charges.

Measurement range 0 - 28.8 V.
