I decided to get the autoenginuity scan tool to check out my truck. The truck has been running well but seems a little underpowered when towing about 18000 fully loaded. Also seems to have some electrical issues like the door ajar sensor is always on even though I replaced all the door ajar sensors and it did not fix the problem. The radio only turns off after you leave the vehicle closed up for 5-10 minutes. Also the headlights don't buzz to let you know they are still on when you leave the vehicle. The dome light sometimes turns on when you get in and other times nothing until the key is turned. I am not able to program a new remote to unlock the doors.
Do I need A NEW vsm?
Truck is 2002 7.3l diesel dually 4.10 gears, 202k miles with ts performance 6 pos chip, afe stage 2, 4" turbo back exhaust. all problems listed above were present before adding mods. After the mods I have good power but high egt's. I just replaced the up pipes and it seems much better but I have not tried it fully loaded. Only ran with the camper in the back so about grossing about 12k lbs. fully loaded I tow a trailer also to get to 18000k.
