EVO-ALL in 2004 Jeep Liberty will not program

0 votes
2004 Jeep Liberty, no factory alarm, with transponder key. EVO-ALL is installed with a Compustar CS800-S. Used installation guide #3317, Connection #1, Program #1. Firmware flashed is 74.[38].

I can get the bypass to enter program mode (solid blue LED). When turning the ignition key to ON, the blue LED turns off and nothing else happens. The guide says the LEDs are supposed to turn on and off BLUE - RED - YELLOW in sequence, taking up to one minute. I waited 5 minutes with no lights turning on. Any advice?

What is the 12 digit service number of the module?

use firmware 4.06 per the guide. J1850 vehicles were removed after that.

The S/N is 001A07064804

I thought I read somewhere that J1850 was re-introduced in the latest firmware.

Flashlink manager does not allow me to re-flash to 4.06 (it is greyed-out), only 4.08. When flashed with 4.08, it still does not program the key.

that would be 74.22.  Cars were never tested though with 74.22 since it would mean finding some older J1850 in the first place. So it's hit or miss

 

If you have an evo-all that starts with 001A06 , you will have access to 4.06. 

 

Or, INT-SL+

I downgraded the firmware to 74.22, plugged it in, and it programmed successfully. All features worked fine.

Thanks for all your help
Hello, after all this time spent on version 74.22 still works just as well on your vehicle? I have a 7 harware and a 2001 Jeep Grand Cherokee ...
