FaultCrate・ABS light with C0265/C0201/U1041 or no communication with brake module (EBCM ground G110)
Upon inspection, DTCs C0265 and C0201 may be set in the brake module.
There may also be a loss of communication with the brake module.
What to do
- The EBCM ground is on the frame beneath the driver's door; among several grounds it is the heavy 12-gauge wire.
- The battery-cable-to-frame ground can cause similar ABS symptoms and can be checked as well.
- Clean the area, front and back, using a tool such as a Scotch-Brite Roloc disc or equivalent.
- Use the bolts, washers and nuts specified in the bulletin because of their conductive finish.
- Cover the front and back of the repair area with rubberized undercoating.
What is needed
- Parts and materials
- The bolts, washers and nuts specified in the bulletin (for their conductive finish)
- Rubberized undercoating (to cover the front and back of the repair area)
- Labor time
- Not stated

Only what the technical documents state. "Not stated" does not mean not needed.
If left
- DTC U1041 can also set in other modules.→ other modules (DTC U1041)
- A poor connection at the EBCM ground is causing brake modules to be replaced unnecessarily.→ unnecessary brake module (EBCM) replacement
Caution
