Service bulletin 04-002-13-2812

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

SOME VEHICLES (EQUIPPED WITH DSC) MAY EXPERIENCE THE ABS WARNING LIGHT ON WITH DTCS C0020:1C AND U0415:92 STORED IN MEMORY. C0020:71 MAY ALSO BE STORED. • DTC C0020:1C: ABS MOTOR MONITOR SIGNAL DOES NOT CORRESPOND TO ABS HU/CM ON/OFF SIGNAL. • DTC U0415:92: ERROR SIGNAL FROM ABS HU/CM OR DSC HU/CM. • DTC C0020:71: DSC HU/CM MOTOR MONITOR ON SIGNAL IS NOT INPUT WITHIN SPECIFIED TIME LIMIT OR MORE WHEN MOTOR SIGNAL IS SWITCHED FROM ON TO OFF BY DSC HU/CM. THIS CONCERN MAY OCCUR IF THE VEHICLE IS USED IN AN AREA WITH HIGH AMBIENT TEMPERATURES AND HUMIDITY. UNDER THESE CONDITIONS, THE PUMP MOTOR BRUSH IN THE ABS HYDRAULIC UNIT MAY HAVE POOR CONTACT CAUSING THE ABS WARNING LIGHT TO TURN ON. TO CORRECT THE PROBLEM, THE MATERIAL OF THE MOTOR BRUSH HAS BEEN CHANGED.
