(1) Measure the resistance between the ECU ground terminal and body ground.
Standard resistance:
Below 1 Ohms
(2) Disconnect the ECU connector. Check the ground terminals on the ECU side and wire harness side for bent terminals, corrosion or foreign
matter. Lastly, check the contact pressure of the female terminals.
Continuity and Resistance Check
CONTINUITY AND RESISTANCE CHECK
Disconnect the battery terminal or wire so there is no voltage between the check points.
Contact the two leads of an ohmmeter to each of the check points.
