Service bulletin T-SB-0174-12 Rev
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.

This DTC may set as a result of an overly sensitive monitoring logic without any other ABS/VSC system issue. Follow the Repair Procedure in this bulletin to properly diagnose the system and, if necessary, replace the ABS/VSC ECU with an ECU containing the updated monitoring logic.
