I'm experiencing an issue with my truck that hopefully someone can help me figure out.
1. My truck has a aftermarket radio.
2. The truck was somehow 'reset' after a nearby lightning strike. (lightning did not strike my truck)
Now there is a communication issue that I believe is caused by the fact that I no longer have the factory radio in the truck. I looked at the electrical schematics and it shows the can c network (which carries the pcm, tcm, abs, and eps modules from the star connector under the passenger side of the dash) goes through the security gateway, and then to the radio. I'm wondering if this is part of the 'anti-theft' system that won't allow communication with the major modules (pcm, tcm, etc.) unless all the factory components are present.
When I unplug the dash harness (inline dash rt), the EVIC immediately comes on, and the fobs, windows, lights, horn, etc. works. As soon as I plug in the dash rt harness, the EVIC immediately goes blank. At first I thought there was an open, a short, bad ground, and a bad harness. I've tested everything and even replaced the complete dash harness, and the dash rt harness with a brand new harnesses. Still no dice! I've even unplugged individual modules from the star c connector just in case a module has gone down. Again, no dice.
I cannot read any DTCs because the DLC is linked to the security gateway and because there is no communication with the can c network, I cannot access the pcm.
I currently do not have my factory radio, so I need opinions about this before I purchase another radio. I'm close to certain that the lack of the factory radio is the culprit here.
Please advise
