# Service bulletin DOR\-Z2E6B\-08

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10178810
- Published by NHTSA: 2020\-08\-24
- Manufacturer's number: DOR\-Z2E6B\-08
- Manufacturer's date: 2020\-07\-08
- NHTSA component: TRAILER HITCHES; ELECTRICAL SYSTEM:SOFTWARE; ELECTRICAL SYSTEM: INTEGRATED TRAILER BRAKE CONTROL

## NHTSA's summary

These SKUs are Trailer Brake Control Modules. The customer communication requested return of unsold inventory due to an internal software issue. The internal software issue leads to a false check trailer brake message and Trailer Brake Controller fault whenever the brake pedal is pressed. This will cause the part to be replaced, due to repetitive dashboard warning light, even though it sends signals to the trailer brakes properly.
