Inspection Procedure

1. NG: Go to step 2 
2. OK: GO TO NEXT STEP 

   END 

1. Check that the transmitter's LED illuminates 3 times when the switch is pressed 3 times.

   OK: Transmitter's LED illuminates 3 times when switch is pressed 3 times. 

1. NG: Go to step   4 
2. OK: GO TO NEXT STEP 

1. Check standard UNLOCK/LOCK switch operation.
   NOTE: Standardized test procedure: press the transmitter switch for 1 second, directing the beam to the driver side door outside handle from a distance of 1 m (3.28 ft.). The transmitter should be pointed directly at the handle, i.e. at a 90° angle to the vehicle body. 

1. NG: Go to step   5 
2. OK: GO TO NEXT STEP 

   REPLACE DOOR CONTROL TRANSMITTER 

1. After replacing the door control receiver, check that the doors can be locked and unlocked by using the transmitter LOCK/UNLOCK switch.

   OK: Doors can be locked and unlocked with transmitter. 

1. NG: REPLACE DOOR CONTROL TRANSMITTER 
2. OK: GO TO NEXT STEP 

   END 

1. Switch to self-diagnostic mode using the hand-held tester.
   1. Connect the hand-held tester (with CAN VIM) to the DLC3.
   2. Turn the power switch ON (IG) and push the hand-held tester main switch ON.
   3. Please refer to the hand-held tester operator's manual for further details.
2. Switch to self-diagnostic mode by operating the key slot.
   1. Put the vehicle under the vehicle's initial condition (See ON-VEHICLE INSPECTION  ), insert the key into the key slot and remove it.
   2. Within 5 seconds of removing the key (step 1), insert the key into the key slot. Then turn the power switch ON (IG) and OFF.
   3. Within 30 seconds of switching the power switch OFF again (step 2), perform the following 9 times: Turn the power switch ON (IG) and OFF.
   NOTE: If the change to self-diagnostic mode has failed, the system will return to normal mode. 

   HINT:

   • Turning the power switch ON (IG) after step 3 has been completed will end self-diagnostic mode.
   • Do not lock or unlock doors during self-diagnostic mode.
3. Check that the system has switched to self-diagnostic mode by checking the flashes of the room lamp (dome lamp or key slot light). Compare the flash patterns of the room lamp to the timing chart on the left.

   OK: 

   Flash patterns of room lamp should be the same as that shown in timing chart on left. 

1. NG: Go to step   9 
2. OK: GO TO NEXT STEP

   Result	Proceed to
   When unmatched recognition code is output	A
   When normal waves (patterns of room lamp) for LOCK, UNLOCK and PANIC switches are output	B
   When no diagnosis outputs are present	C

1. B: REPLACE INSTRUMENT PANEL JUNCTION BLOCK ASSY (MULTIPLEX NETWORK BODY ECU) 
2. C: Go to step   8 
3. A 

1. Check that the system can switch to rewrite mode or add mode and that a recognition code can be registered.

   OK: System can switch to rewrite mode or Add mode and that recognition code can be registered. 

1. NG: Go to step   15 
2. OK: GO TO NEXT STEP 

   END 

1. When a new or normally functioning door lock control transmitter switch for the same type vehicle is held down, check that an unmatching recognition code is output.

   OK: Unmatching recognition code is output. 

1. NG: Go to step   12 
2. OK: GO TO NEXT STEP 

   REPLACE DOOR CONTROL TRANSMITTER 

Result: 

1. B: Go to step   5 
2. A
