There is a security relearn I can post here for you to correct this but first I need to know if this is the classic or new body style as 1999 both bodies were released.I can tell this by the engine liter size.Can you post what liter engine is in this model here and I will post the procedure you need below.
Try this procedure below as this should relearn the theft system.Do this with a fully charged battery.If a step is missed the procedure will need started over again.
1. Insure the ignition key is in the ON position. 2. Clear all EVO/passlock module and VCM/PCM DTCs. ( you can skip this step )
3. Momentarily rotate the ignition key to the CRANK position (Do NOT start the vehicle), then release it to the RUN position (Do NOT key OFF in the process). 4. Wait 10 minutes. Observe the SECURITY indicator.
5. The SECURITY indicator will transition from flashing to ON briefly to OFF after 10 minutes if remaining in the ignition ON position. 6. Turn the ignition switch to the OFF position and wait for 10 seconds. 7. Repeat steps 3 through 6 two more times. The new security code is ready to be communicated among the Passlock sensor, EVO/Passlock module and VCM/PCM. The new password ***** ***** on the next ignition lock cylinder cycle from OFF to CRANK to ON (start attempt).The engine should now start.
