2. Measure the voltage between the terminals of the electronic control unit connector on the wiring harness side and ground (conclusion "GND") with the connector connected. Compare the obtained values with the data in the table "Voltage at the terminals of the connector of the control unit for vehicle controllability improvement systems".
Note:
- Before testing, make sure the battery voltage is 10-14V.
- Tests are carried out with the connector on the wiring harness side connected.
