Diagnostic Procedure

STEP

INSPECTION

ACTION

1

INSPECT LOCK/UNLOCK OPERATION

Lock and unlock all doors from the door lock control switch.
Do all the doors lock and unlock correctly?
Yes
Go to the next step.
No
2

DTC INSPECTION

Is the DTC displayed?
• B2425
Yes
No
Go to the next step.

INSPECT TRASMITTER OPERATION

Note
• If the vehicle is within 0.8 km {0.5 mile} of radio or TV towers, the operating distance of the transmitter may be reduced.
Press each button on the transmitter while standing 3 m {10 ft} away from the vehicle.
Is there an appropriate response for each button pressed?
Yes
The system is normal.
No
Go to the next step.
4

INSPECT ANY RESPONSE FROM TRANSMITTER NO. 1

Stand next to or sit inside the vehicle.
Press each button on the transmitter.
Does the system respond to all the buttons pressed from transmitter No. 1?
Yes
Go to Step 6.
No
Go to the next step.
5

INSPECT ANY RESPONSE FROM TRANSMITTER NO. 2

Stand next to or sit inside the vehicle.
Press each button on the transmitter.
Does the system respond to all the buttons pressed from transmitter No. 2?
Yes
Go to the next step.
No
REPROGRAM transmitter No. 1.(See TRANSMITTER ID CODE PROGRAMMING.)TEST the system for normal operation. If the transmitter still does not operate, CHECK the battery. If battery is OK, a new transmitter is necessary.
Inspect the system for normal operation.
6

INSPECT THE TRANSMITTER TIC AND DATA

Select GEM, FUNCTION TESTS, TRANSMITTER TIC/DATA from the WDS or equivalent menu.
Is there at least one transmitter stored and displayed next to TIC 1?
Yes
Go to the next step.
No
PROGRAM all of the transmitters.(See TRANSMITTER ID CODE PROGRAMMING.)
Inspect the system for normal operation.
7

INSPECT THE LAST TIC RECEIVED

Select GEM, FUNCTION TESTS, TRANSMITTER TIC/DATA from the WDS or equivalent menu.
Press and release the UNLOCK button of a transmitter. The transmission received contains TICs for the transmitter being operated and DATA for the button which has been pressed.
Does an eight digit alpha-numeric code appear for the LAST TIC RECEIVED and does the LAST DATA RECEIVED match the button press?
Yes
Go to Step 9.
No
Go to the next step.
8

INSPECT TIC AND DATA FOR THE SECOND TRANSMITTER

Repeat Step 7 for the second transmitter.
Does an eight digit alpha-numeric code appear under the LAST TIC RECEIVED and does the LAST DATA RECEIVED match the button pressed?
Yes
Inspect the battery of the transmitter(s). If battery is OK, a new transmitter(s) is necessary. PROGRAM the transmitter(s).(See TRANSMITTER ID CODE PROGRAMMING.)
Inspect the system for normal operation.
No
Go to the next step.
9

INSPECT THE TRANSMITTER TIC AND DATA

Select GEM, FUNCTION TESTS, TRANSMITTER TIC/DATA from the WDS or equivalent menu.
From the WDS or equivalent tool FUNCTION TEST, monitor the Transmitter TIC/DATA using the recorded alpha-numeric codes from Step 7.
Is the TIC RECEIVED one of the TICs RECORDED in Step 7?
Yes
Go to the next step.
No
PROGRAM the transmitter(s). (See TRANSMITTER ID CODE PROGRAMMING.)
Inspect the system for normal operation.
10

INSPECT TIC/DATA FOR DATA MATCH

Select GEM, FUNCTION TESTS, TRANSMITTER TIC/DATA from the WDS or equivalent menu.
From the diagnostic tool FUNCTION TEST, monitor the Transmitter TIC/DATA.
Does each button pressed on the transmitter create the expected LAST DATA RECEIVED output?
Yes
Go to the next step.
No
PROGRAM the transmitter(s). (See TRANSMITTER ID CODE PROGRAMMING.)REPEAT Step 3.
11

INSPECT THE GEM FOR CORRECT OPERATION

Inspect for the following items:
• corrosion
• pushed-out pins
Connect all GEM connectors and make sure they seat correctly.
Operate the system and verify the concern is still present.
Is the concern still present?
Yes
Clear the DTC and repeat the DTC inspection.
No
The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector.
Clear the DTC and repeat the DTC inspection.
