Went to start 2017 Jeep Wrangler 3X Lock and Alarm went off.

Question

Updated firmware and now when I cycle key and solid blue to flashing blue, when I hit the lock button all colors of the led flash and nothing works. The unit had been working for the last 14months with no issue.

Answer 1

After further testing it would appear the Fortin module is at fault. Checked fuses and power glall good. Reflashed module with latest Firmware and flashed the revised A, C and D values and now the module can't be changed. At Max number of flashes for the module, with the module disconnected vehicle starts and runs fine and CAN faults go away. Inspected wiring for chaffing none found, removed and and recrimped all connections, and disconnected and reconnected harness. Reconnected module and got solid blue light, cycled key to RUN and got flashing blue, cycle key to OFF and press the LOCK button with key in cylinder nothing still flashing. Remove key press LOCK and module flash all LEDs Blue Yellow Red all together, flashes 15 to 20 seconds then nothing.
