Service bulletin 131-26004

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.

NHTSA's summary

Under certain conditions the warning message shown to the right can be activated in the driver display when both the brake lamps and a turn signal are activated at the same time. The cause of this issue has been identified as the unique Federal rear lamp combined position/brake/turn indicator configuration. Even with this message displayed, the tail lamp and turn signal should work as intended. Fit the tail lamp link harness between the connectors. Repeat the procedure on the right-hand side rear tail lamp. Put the vehicle into active or driving mode and activate the brake lamps and turn signals at the same time to ensure that the warning massage does not appear in the driver display before refitting the wheel arch liners and rear wheels.
