Checking the ABS circuit

1. Check the battery voltage with the ignition off.

• Rated voltage - 10-14 V

2. With the ignition off, disconnect the ABS control unit connector and check the resistance and continuity between the ABS control unit connector terminals (see table "Resistance between conclusions of a socket of the electronic block of management ABS").

3. Measure the voltage at the terminals of the ABS control unit connector with the ignition on (see table "Voltage at the terminals of the ABS control unit connector").

Note: before measuring, check the battery voltage (with the ignition on - 10-14 V) and resistance between terminal "Earth" and body (with the ignition off - no more than 5 ohms).
