Service bulletin 167-B1527-12

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

SB-15-030 On subject vehicles, the MIL (Malfunction Indicator Lamp) may illuminate with DTC (Diagnostic Trouble Code) U02A2 stored in the engine ECU. This may be due to a malfunction of the DEF (Diesel Exhaust Fluid) tank sensor assembly. Perform the diagnostic procedure for DTC U02A2 as outlined by the Workshop Manual (DEF SCR System Section for Conventional Vehicles, Engine Troubleshooting Section for COE Vehicles). If the diagnostic procedure leads to DEF tank sensor replacement, a more robust DEF tank sensor has been made available.
