1.  Remove the front side trim (LH). (See FRONT SIDE TRIM REMOVAL/INSTALLATION.)

2.  Verify that the voltages of each of the terminals are as indicated in the terminal voltage table (reference) (See 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 work normally even though the inspection items are normal, identify the malfunctioning location according to the directions in [DIAGNOSTIC SYSTEM] and [SYMPTOM TROUBLESHOOTING] then perform repairs.
