INSPECTION PROCEDURE

1. Connect the intelligent tester to the DLC3.
   

2. Turn the ignition switch on (IG) and turn the tester ON.
   

3. By following the tester screen display, check whether any DTCs are output.
   

   OK:

   No DTC output.
   

1. Check that all the doors lock when the door control switch (for manual operation) is turned to LOCK and all doors unlock when turned to UNLOCK.
   

   OK:

   All doors can be locked and unlocked with door control switch.
   

1. Connect the intelligent tester to the DLC3.
   

2. Turn the ignition switch on (IG).
   

3. Turn the intelligent tester on.
   

4. Enter the following menus: Body / Main Body / Data List.
   

5. Read the Data List according to the display on the intelligent tester.
   
   

   Main body ECU:

   Item	Measurement Item / Range (Display)	Normal Condition	Diagnostic Note
   P-Door Lock Pos SW	Passenger side door lock position switch signal / ON or OFF	ON: Passenger side door is unlocked OFF: Passenger side door is locked	-

   OK:

   On the intelligent tester screen, the display changes between ON and OFF as shown in the chart above.
   

1. Select the Active Test, use the intelligent tester to generate a control command, and then check that the oscillator operates.
   
   

   Certification ECU:

   Item	Test Details	Diagnostic Note
   P-Seat Outside Transmitter	Front passenger side door electrical key oscillator ON / OFF	-

   OK:

   When key is brought close to door oscillator that is ON, indicator light on key illuminates.
   

1. Disconnect the E63 ECU connector.
   

2. Disconnect the Y2*1 or Z2*2 oscillator connector.
   

3. Measure the resistance of the wire harness side connectors.
