DIAGNOSIS AND TESTING
The DTC is always a 5 digit alphanumerical
code, for example
"POI 00".
The first digit of a code (letter) identifies the
system which has set the code. Provision has
been made for a total of four systems to be
identified although only the
'PI code is required
for EOBD.
- 'B' for the body
- 'C' for the chassis
- 'P' for the powertrain
- 'U' for the network communications systems
All of the
"xOxxxW codes are standardized codes.
However, any manufacturer can use additional
codes over and above the standardized codes.
These will be labelled
"xlxxx"
The third digit of a code (numeric) identifies the
sub-system which has set the code.
- 'Pxlxx' for metering of fuel and air supply
- 'Px2xx' for metering of fuel and air supply
- 'Px3xx' for ignition system - combustion
misfires
- 'Px4xx' for auxiliary emission control
equipment
- 'Px5xx' for vehicle speed, idle setting and
other related inputs
- 'Px6xx' for trip computer and other related
outputs
- 'Px7xx' for transmission.
- 'Px8xx' for transmission.
- 'Px9xx' category to be determined
- 'PxOxx' category to be determined
When a concern occurs, the actions taken
include storage of the relevant information and
actuation of the MIL occurs in line with the
relevant legislation.
