ABS Circuit Check — Diagnostics [Toyota Duet M100]

1. Disconnect the ABS control unit connector and measure the resistance and voltage between the terminals of the wire harness connector (see the table "Circuit between the terminals of the control unit wire harness connector with the ignition off").

2. Measure the voltage between the terminals of the electronic control unit connector on the wiring harness side and the ground ("GND" terminal) with the connector connected. Compare the obtained values with the data in the table "Voltage at the terminals of the control unit connector of the vehicle control systems improvement".

Note:

• Before testing, make sure the battery voltage is 10-14V.
• Checks are carried out with the connector connected on the wiring harness side.
