1. Checking the purpose of the system with connected connectors.
- A) Remove the ABS control unit.
- b) Using a voltmeter with a large input resistance (minimum 10 kOhm/V), measure the voltage between each pin and ground". If the circuit does not meet the requirements, then, using the table, find and fix the fault.
2. Checking the purpose of the system with disconnected connectors.
- A) Disconnect the connectors from the electronic control unit, check the circuit from the side of the wires. If the circuit does not meet the requirements, then, using the table, find and fix the fault.
- b) Connect the connectors and install the electronic control unit in place.
