DOOR-ELECTRICAL SUPPLY UNIT INSPECTION [(E)]


id0940007013x2

1.  Disconnect the negative lead-acid battery terminal. (See NEGATIVE LEAD-ACID BATTERY TERMINAL DISCONNECTION/CONNECTION.)

2.  Remove the following parts:

(1)  Inner garnish (See INNER GARNISH REMOVAL/INSTALLATION.)
(2)  Power window main switch (to remove from driver’s side) (See POWER WINDOW MAIN SWITCH REMOVAL/INSTALLATION.)
(3)  Power window subswitch (to remove from passenger’s side) (See POWER WINDOW SUBSWITCH REMOVAL/INSTALLATION.)
(4)  Front door trim. (See FRONT DOOR TRIM REMOVAL/INSTALLATION.)

3.  Connect the negative lead-acid battery terminal. (See NEGATIVE LEAD-ACID BATTERY TERMINAL DISCONNECTION/CONNECTION.)

4.  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.
