Hi, glad to be of help. I have a differing opinion.
From the codes you listed, you most likely have a bad EBTCM.
Many people have had EBTCM issues, and they tend to go bad on these cars.
Probe the 3 wires going to the flasher module, check for shorts to ground, shorts to voltage, grounds, opens, AND reference voltage. Check for corrosion at all terminal pin connections on EBTCM.
Check for corrosion on the Maxi-fuse terminals that may be causing a high resistance and verify there is 12 volts on both sides of the fuses.
The EBTCM circuit ties into the turn signals. Check or replace turn signal bulbs. The turn signal sockets are also known for going bad, so visually inspect the contacts on your turn signal socket to make sure there are no burn marks or melted
plastic in the housing. Flick the blinker on with the turn signal stalk and use a voltmeter to see what type of voltage you are getting at the bulb socket contacts. If all connections and reference voltages are good, replace EBTCM.
TRACTION CONTROL SYSTEM DESIRED TORQUE CIRCUIT
Traction Control System (TCS) uses Anti-lock Brake System
(ABS) in conjunction with PCM fuel and ignition controls to
drive wheel slippage during acceleration.
You likely won't notice any drivability problems.
Desired torque signal Pulse Width Modulation (PWM) is less
than 5 percent or greater than 95 percent.
Check for faulty connection at EBTCM. (Electronic Brake and
Traction Control Module)
U1040 shows that
communications has been lost with the electronic brake control module.
This relay inside the EBCTM is what usually goes bad.
