Generator

Open circuit in the generator input (P2502)

The PCM believes that the generator output voltage - above 17 V, and the voltage at the positive terminal of the battery - below 11 V.

No signal generator output voltage (P2503)

The PCM generator requires a current of 20 A, and believes that the generator output voltage below 8.5 V when the engine is running.

Overcharging the battery (P2504)

The PCM believes that the generator output voltage - higher than 18.5, or the voltage at the positive terminal of the battery - above 16 during engine operation.

Bus fault CAN (U0073)

CAN controller is damaged.

The PCM does not receive signals from the antilock brake system (U0121)

The PCM does not receive a signal from the control unit Anti-lock braking systems.
