When replacing the wireless access module, it is necessary to write the vehicle information into the new wireless access module.
During the replacement procedure, the same scan tool must be used from start to finish. If the scan tool is changed midway, information cannot be written correctly.
If the wireless access module, ECM, or steering lock assembly has been replaced, or if electronic keys have been replaced or added, make sure to perform security information programming.
Use the following procedure when performing programming after replacing the wireless access module.

When the wireless access module, ECM, steering lock assembly, or electronic key is reset or programmed using a scan tool, you will be requested to enter the 4-digit security code. This code is shown on the vehicle security information card issued for new vehicles. If the card is unavailable, contact the service department of the Isuzu distributor to obtain the security code.
Legend
For new owners, distributors or dealerships must provide a vehicle security information card that shows the identification numbers of the owner's vehicle immobilizer system. This information is very important in case of repair or if the transponder keys or electronic keys are lost. Dealers are responsible for providing the following three items.
Save all the vehicle security codes as confidential data. If the vehicle security information card is lost, data must be requested from the service department of Isuzu distributor. This request will only be processed if accompanied by the specified form and proof of ownership. Once the data is received, it will be entered onto a blank card and given to the customer. Any unused cards should be destroyed. Instructions on filling out the "Data Request Vehicle Security Information Card" are as follows.
The data requested under items 1 to 10 must be provided in full, including the authorized dealership number, the vehicle identification number (VIN) and engine type/number.
The form must be completed by entering the data and signature/authorized dealership stamp, and then sent along with proof of ownership to the address provided in the form.
After confirming that the information is correct, the requested data should be sent by fax to the dealership that made the request.
The security code is necessary to reset or program the wireless access module, ECM, steering lock assembly, and electronic keys. If an incorrect code is entered when the scan tool requests the security code to be entered, the wireless access module or ECM will go into a security wait status. This wait status will prevent any further attempts to enter the security code until the wait time has elapsed. If an incorrect security code is entered again after the initial wait time has elapsed, the wireless access module or ECM will go into a second wait time status. The wait time will increase each time an incorrect code is entered. If the correct code is entered, the wait time will reset back to its original value of 10 seconds.
