The EBCM stores only one service code at a a time, even
though it may detect more than one fault condition. The
first fault detected results in a stored service code. The
detected fault must be corrected, and the service code

additional codes can be stored.
After the first fault is corrected and the service code is
erased, drive the vehicle at a speed greater than 35 mph
to set any additional service codes.
