DOOR-ELECTRICAL SUPPLY UNIT INSPECTION

DOOR-ELECTRICAL SUPPLY UNIT INSPECTION

SM2336734


id094000005200

1.Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(US)].)

2.Remove the front door trim. (See FRONT DOOR TRIM REMOVAL/INSTALLATION [(US)].)

3.Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION [(US)].)

4.Verify that the voltages of each of the terminals are as indicated in the terminal voltage table (reference).

• If the voltage is not as specified in the terminal voltage table (reference), inspect the parts under Inspection item(s) and related wiring harnesses.
― If the system does not operate normally even though the inspection items are normal, replace the door-electrical supply unit. (See DOOR-ELECTRICAL SUPPLY UNIT REMOVAL/INSTALLATION.)
