- If, with a completely discharged battery, an external power source is connected via jumper wires to start the engine and the car immediately starts moving (without giving the discharged battery some time to recharge), the ignition system may begin to fail, which will lead to the car stopping and the inability to continue moving.
- This phenomenon occurs as a result of the high current consumption of the ABS system for self-diagnosis. To avoid this phenomenon, it is necessary to either allow the battery to charge with the engine idling, or to disable the ABS system by removing the fuse from the ABS circuit (Fig. 15.76). In this case, the ABS indicator lamp will light.

Once the battery is sufficiently charged, turn off the engine, reinstall the ABS fuse and start the engine again. Make sure that the ABS warning light is off.
