buddie of mine has a 2007 RR and had an idiot install a new instrument cluster....upon putting it together things went down south. spent 12hrs on it but we were unable to get it to start.Here is a timeline of what happened:
-installer put the cluster in and started the car to ensure it was working properly before re-assembling everything. car started fine and cluster seemed to work fine. He shut off car and proceeded to finish re-assembling the console. i noticed the headlights had been on and right before he put the final piece i asked him to start the car just to be safe. It would not turn. horn worked fine, lights worked but car would not turn. seemed like it was immobilized. the different lights in the cluster started flashing with the parking brake and AFS indicators blinking faster than normal. at this point horn and headlights worked fine so i figured it was not the battery. Also, at this point, the messages, "Engine system fault", Transmission system falut" "tire monitoring system fault"and "check brake pads" were being displayed in the message display. Also, the lights would be flashing like in an armed mode.
We hooked it up to his Toyota sienna thinking the battery was a little drained but still no luck at starting the car. thinking the battery on the sienna was not strong enough, I called roadside assistance and they came with a big battery. Same thing...no luck at starting .
We disconnected the battery for a while (but did not leave key in ignition. i later saw online something about leaving key in ignition when disconnecting battery. After a while, connected it back but no luck. At this point however, I noticed the system seemed to have returned back to normal (as in when key is turned, the instrument panel lit up as normal when turned to ignition and the lights weren't flashing like crazy and the messages were gone BUT the car would still not start when turned to end ).Noticeable also by now was the low battery as the headlights didnt come on and interior lights were very dim. Connected sienna to it again and the ignition came back to life and all lights worked and interior lights brightened up. But still turning the car to start still proved abortive. This made me believe that the security system of the car might have shut down the entire car. Roadside called tow truck and we had it flatbedded to my friends shop. This was at 3.30am...all the way from 6pm in the evening. FML
I know these cars are very senstitive and something as simple as a drop in the battery voltage could have led to all this. I am seriously hoping and praying its just a matter of drained battery and system reset and nothing else. We are scheduled to fly out on Friday and would love for this to be resolved before then.
Has anyone experienced this before or have any insight on the situation. All inputs are greatly welcomed and appreciated.
