RM1
Measure the resistance between terminal 44 and terminal 3 of the 70 pin connector.
Measure the resistance between terminal 44 and 3 and the engine block surface.Expected Result:Each check of the resistance is greater than 2 Ohms.Results:
OK - Each check of the resistance is greater than 2 Ohms. The wiring for the power supply does not have a short circuit. Proceed to Test Step 4.
Not OK - At least one check of the resistance is less than 2 Ohms.Repair: Repair the wiring, when possible. Replace parts, if necessary. Verify that the
