Checking the ABS circuit [Toyota Carina T190]

1. Check the battery voltage with the ignition off.

• Nominal voltage - 10-14 V

2. With the ignition off, disconnect the ABS control unit connector and check the resistance and conductivity between the terminals of the ABS control unit connector (see the table "Resistance between the terminals of the ABS electronic control unit connector").

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 taking measurements, check the battery voltage (with the ignition on - 10-14 V) and the resistance between the ground terminal and the body (with the ignition off - no more than 5 Ohm).
