Be sure the light on the side of Pro Bypass module lights when the key is turned on. If there is no light then the Red or Black wire are not getting the power and ground. If the light is on then proceed with the instructions.

 

Turn off the key and open the PRO Module cover (this will NOT void the warranty) by removing the 2 screws on the bottom. Inside there are 2 sets of switches

 

1, Set SW1 (8 switches) as following:

 

2. Set SW2 (10 switches) as indicated in the first row of the table below.

 

3. Try to start the engine. If engine starts then replace the cover on the PRO Module, the installation is completed. Otherwise if the engine still doesn’t start, turn off the key and remove it from the tumbler, wait 4 minutes and then continue with step #4 here below.

4. Repeat step #3 above, but with SW2 as in row 2 of the table, then if still doesn’t start repeat again with SW2 as in row 3 of the table and so on until the right code is found and the engine will start.
