This is my first post but I’ve read through tons of post on this site over the years. Unfortunately I have not found a fix to my new problem. I have a 2006 LR3 with approx 180k miles on it. It’s been a great ride. Drove it one day with my dogs and one of them was standing on the downhill assist button(don’t think this caused my issue)came home dropped them off and went to get back in and would not start. All I get is the faint click with the hazards going on and off and the locks locking. My security light flashes and park brake is red with my temp gauge maxed out, with all the other alarms. My scan tool says “communication failure”. What I’ve done. Checked all fuses and relays, installed new battery, sent the cluster off to be repaired, checked what grounds I could find, checked the Tccm for corrosion. Still have have not gained anything. I can jumper the starter solenoid and it will turn over but won’t fire. I’m at a loss. It seems alot of people had luck with the Insturment cluster but that didn’t seem to be my problem. Any help would be great.
