Diagnostic Trouble Code (DTCs) -- Trouble codes are how
OBDII identifies and communicates to technicians where and
what on-board problems exist. The first number in the DTC
indicates whether the code is an SAE generic code (applies to
all OBDII systems) or is specific to the vehicle manufacturer.
The remaining three numbers provide information regarding the
specific vehicle system and circuit. An analysis of a typical
OBDII code is shown below. For more details on training, contact us at www.bimi.com.ng, info.bimi.com.ng, 07065939633
