A) Disconnect the connectors from the electronic control unit.
b) Remove the retainers as shown in the figure to allow easy connection of tester probes.
Note: be careful with the elements "A" And "IN", which can be easily broken, especially in cold weather.
V) Reconnect the connectors to the electronic control unit.
Note:
- Perform all voltage measurements with connectors connected.
- The battery voltage must be at least 11V with the ignition on.
Using a voltmeter with a large self-resistance (not less than 10 kOhm/V), measure the voltage at each output of the electronic control unit.
