Traction control error code on dash after radio install
#14
U1017 - Lost Communication With Engine Control Module
U1000 - a generalized issue with the data bus, as well as circuit issues like damaged or poorly-done wiring and connections, or potentially a module that has failed.

Who installed this radio?
The unrelated codes seem to point to whomever did the install F'd up. Seems like the installer was poking around with a test light or meter in the wrong places and has no idea what they are doing and/or connected wires incorrectly!
The new radio installation might have fried a portion of your BCM.
*U1000 Generally, this DTC indicates a faulty control module or circuit. The secondary code helps pinpoint the specific cause. If there are no other active codes, faulty grounds, damaged/corroded wiring or a bad connector contact at the module junction/wiring harness could have triggered the U1000 code. the second code U1017 Lost communication with engine control module (ECM).
*b2602 The BCM stores DTC B2602 in memory. ○ The BCM disables the DRL relay control as long as the fault is present. ○ The BCM disables the DRL relay
*u1301 Voltage supplied to the module is in the normal operating voltage range. The vehicle power mode requires serial data communication to occur. The class 2 serial data circuit is shorted high or low for approximately 3 seconds.

maybe the radio illumination wire that supplies the radio from the factory harness is grounding out and shutting down the module. on aftermarket radios harnesses i think its either orange or orange with a white stripe. another issue can be the radio interface module they installed to retain steering control and chimes is pulling down the network bus.

Fixed traction control failure
Ok here was the fix for two issues.
1) the main issue was the bcm brake control module failure. I replaced this as it was causing the code that low brake pressure. Remember I didn’t have an abs failure just traction control.
2) I had replaced 2 led bulbs in the rear backup lights. These where causing an error code.

Just in case I would run a scan again even it doesn’t show any problems.
Never heard of that a simple light bulb can trigger a code error other than the knock off china spy bulbs.
