MY 2012 ELECTRICAL ISSUES CAME ALL AT ONCE.
- No exhaust brake indicator
- No horn
- No signal lights
- No tow/haul
- No wiper
The new TIPM did not have any effect; $600 down the toilet!
Any ideas?

The scanner indicates that it is unable to communicate with the truck.
I am trying to find a common point of connection or signal.
The truck was an Air Force Fire Chief vehicle, and it has only 95,000 miles on it.
Almost ready to sell it cheap!
It's impossible to know what they did to it.Originally Posted by JUMARTZ
Have you checked all fuses and all the grounds?
Have you done a load test on both batteries?
If you have one battery that is low or bad, that would cause all kinds of havoc to the electrical system.
Recommend replacing both batteries, even if only one is faulty.
Please keep us updated.

It has been a reliable vehicle since November 2020.
I put new batteries in two years ago.
Will check them today.
I am scratching my head on this one.
Yeah, electrical gremlins can be a nightmare.
Check the batteries, all fuses, and clean all grounds to ensure they are making good contact.
Also, check all your wiring harnesses for rodent intrusion.

For the scanner, if there is no communication issue, I would start at the DLC and test the CAN lines as described in the 2012 service manual on page 886.

You have to get a scanner that can read codes.
Older OBD scanners are incompatible with new CAN units.
If yours is capable but still not communicating, you need to check the network.
This was electrical items, not engine, this may point to IHS or internal high speed CAN network.
The components will require a power and a ground, as well as a twisted pair of wires.
If there are no communications, check for an open CAN or a missing power/ground connection.
Check all fuses and examine the wiring diagram for dead systems; what do they have in common?
First look for their power source, then look at their grounds, then look at the network pair of wires.
Poor body grounds can also lead to trouble.
Are there any water leaks inside?
