Programming Procedures
Programming Procedure for '98 ModelsThe PRG (Program) pin of the Wireless Door Lock ECU is grounded to perform programming. This is accomplished by accessing the Wireless Door Lock ECU directly, as there is NO PRG wire connecting to a satellite location.
NOTE:
Up to two remotes can be programmed to operate each vehicle.
1. With the key OUT of the ignition switch, locate the Wireless Door Lock ECU.
2. With the ECU still connected, locate terminal number 9, PRG (empty) and terminal number 1, GND (black-white wire) in the 15 cavity Wireless ECU connector.
3. Using a suitable jumper wire, insert one end to terminal number 1 and insert the other end through the empty terminal number 9 cavity to touch the PRG pin of the ECU (see illustrations). The vehicle confirms programming mode by requesting the power door locks to lock.
4. Depress, then release, any button on the remote. The vehicle confirms registration by requesting the power door locks to lock once again.
5. To program an additional remote, repeat Step 4.
6. Disconnect the jumper wire to exit programming mode.
Programming Procedure for '99 Models
A. For the 1999 model year, instead of grounding the PRG (program) circuit as in the 1998 model, a unique sequence of ignition switch and door inputs is used for programming. Additionally, there are now two modes: Rewrite and Confirmation.
^ In Rewrite mode, all previous codes are erased and new ones can be added.
^ Confirmation mode reveals how many remotes are currently registered.
NOTE:
Up to four remotes can be programmed to operate each vehicle.
B. To access either mode, start oft by having the:
^ Key out of the ignition
^ Driver's door open and unlocked
NOTE:
Avoid pausing between steps 1 - 7. Programming the first remote should take approximately 45 seconds.
1. Insert (do not rotate), then remove key from the ignition switch.
2. At the Master Switch on the driver's door, use an even pace and actuate the power door lock rocker switch to obtain five LOCK/UNLOCK cycles in less than ten seconds.
NOTE:
One cycle equals a lock command followed by an unlock command.
3. Close, then open the driver's door
4. Repeat the LOCK/UNLOCK sequence as described in step 2.
5. Insert key and cycle the ignition switch LOCK/ON/LOCK
a. Two times to request Rewrite mode
b. Three times to request Confirmation mode
6. Remove key from ignition switch.
a. If the Rewrite request is recognized, the vehicle will respond by cycling the power door locks LOCK/UNLOCK twice to confirm Rewrite mode.
b. If the Confirmation mode is recognized, the vehicle will respond by cycling the power door locks LOCK/UNLOCK from 1 to 4 times to indicate how many remotes are currently registered. If no remotes are registered the door locks will cycle 5 times.
^ If there is no response, return to step number 1 and try again.
7. If Rewrite mode has been confirmed, as in Step 6a:
a. Depress, then release, both the Lock and Unlock buttons, simultaneously on one remote.
b. Depress, then release, one of the buttons, either Lock or Unlock, on the same remote again. The vehicle will respond by cycling the power door locks LOCK/ UNLOCK:
Once to confirm if the remote was registered.
Twice to indicate an incomplete or erroneous procedure.
When adding an additional remote(s), repeat Steps 7a and 7b for each remote.
C. Rewrite mode is terminated if one of the following occurs:
^ More than fifteen seconds have elapsed since Step 7b.
^ The driver's door is closed.
^ The key is inserted in the ignition switch.
^ Four remotes have been registered.
