Inspection Procedure

1. When the door control switch on the master switch assembly is operated, check that the locked doors unlock (See OPERATION CHECK ).

   OK: 

   Locked doors unlock  .

   NG: GO TO POWER DOOR LOCK CONTROL SYSTEM (See  HOW TO PROCEED WITH TROUBLESHOOTING  ) 

   OK: Go to Next Step 

1. Check that the key reminder warning buzzer operates normally.

   OK: 

   Key reminder warning buzzer operates normally  .

   NG: GO TO KEY REMINDER WARNING SYSTEM (See  KEY REMINDER WARNING SYSTEM  ) 

   OK: Go to Next Step 

1. When another registered door control transmitter is used, check that the wireless function operates normally.

B: Go to step  5

A: Go to Next Step 

1. Remove the transmitter battery from the transmitter (See TRANSMITTER BATTERY ).
2. Measure the voltage according to the value(s) in the table below.

   Standard Voltage 

NG: REPLACE TRANSMITTER BATTERY (See  REPLACEMENT  ) 

OK: REPLACE DOOR CONTROL TRANSMITTER MODULE 

1. Bring the transmitter near the door control receiver, and perform a wireless operation check.

   HINT:

   • When the transmitter is brought near the door control receiver, the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
   • If the inspection result is that the problem only occurs in certain locations or times of day, the possibility of wave interference is high. Also, added vehicle components may cause wave interference. If installed, remove them and perform the operation check.

     OK: 

     Wireless functions operate normally  .

     NG: AFFECTED BY WAVE INTERFERENCE 

     OK: Go to Next Step 

1. Switch to self-diagnostic mode by operating the ignition key cylinder.
   1. Make sure that the vehicle is in its initial condition. Then insert the key into the ignition key cylinder and remove it.
   2. Within 5 seconds after removing the key, insert the key into the ignition key cylinder (ignition switch off). Then turn the ignition switch to ON and off.
   3. Within 30 seconds after turning the ignition switch off, perform the following operation 9 times: turn the ignition switch to ON and then off.
      NOTE: If the system cannot enter self-diagnostic mode, the system returns to normal mode.

      HINT:

      • Turning the ignition switch to ON after the above operations have been completed ends self-diagnostic mode.
      • Do not lock or unlock doors during self-diagnostic mode.

B: Go to step  8

C: Go to step  9

A: REPLACE MAIN BODY ECU 

1. Check that the system can be switched to rewrite mode or add mode, and that a recognition code can be registered (See REGISTRATION ).

   OK: 

   Recognition code can be registered  .

   NG: Go to step  13

   OK: END (GO TO OPERATION CHECK) (See  OPERATION CHECK  ) 

1. Prepare a door control transmitter from another vehicle.
2. Press and hold down the door control transmitter switch.
3. Check that a mismatched recognition code is output.

   OK: 

   Mismatched recognition code is output  .

   NG: Go to step  10

   OK: REPLACE DOOR CONTROL TRANSMITTER MODULE 

1. Disconnect the door control receiver.
2. Measure the resistance according to the value(s) in the table below.

   Standard Resistance 

   RESISTANCE SPECIFIED CONDITION
   
   

   Tester Connection	Condition	Specified Condition
   M13-1 (GND) - Body ground	Always	Below 1 Ω

3. Measure the voltage according to the value(s) in the table below.

   Standard Voltage

NG: REPLACE DOOR CONTROL RECEIVER (See  REMOVAL  ) 

OK: Go to Next Step 

1. Disconnect the E63 main body ECU connector and the M13 door control receiver connector.
2. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to Next Step 

1. Temporarily replace the door lock control receiver with a new or known good one (See REMOVAL ).

1. Perform Registration (See REGISTRATION ).

1. Check that the doors can be locked and unlocked by using the transmitter LOCK and UNLOCK switches.

   OK: 

   Doors can be locked and unlocked using the transmitter  .

   NG: REPLACE MAIN BODY ECU 

   OK: END (DOOR CONTROL RECEIVER IS DEFECTIVE)
