Checking the resistance and continuity between the terminals of the ECM unit (Mitsubishi Colt 5)

1. Turn the ignition key to the "ON" position.

2. Disconnect the control unit connector. The engine control unit from the wire connection side is shown in Figure 8.3.



3. Measure the resistance and, according to Table 8.6, check for electrical continuity between the control unit terminals on the wire connection side.

Attention! The testing process does not necessarily have to be carried out in the sequence given in the table - Observe the correspondence of the connection and grounding of the terminals, otherwise all devices may fail.

4. If the ohmmeter shows deviations from normal values, check the corresponding sensor, its connection and wiring. Repair or replace it if necessary.

5. After repair or replacement, check with an ohmmeter whether the faults in the readings have been eliminated.
