Service bulletin 167-T2304-2

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

L-SERIES ANTI-LOCK BRAKE SYSTEM (ABS) MALFUNCTION MESSAGE. If Wabco fault SPN 807 FMI 13 is stored in the ABS module, confirm if the vehicle is equipped with traction and stability control. If the vehicle is NOT equipped with the traction and stability control option, inspect the front brake relay valve under the cab to see if the chassis harness connector is plugged into the front brake relay valve. If the chassis harness connector is plugged into the front brake relay valve, this connector should NOT be connected. Disconnecting the connection at the front brake relay valve and clearing the code from the ABS module will resolve the active Wabco fault code.
