OBD2 OBD II Trouble Codes and Errors. Deciphering Diagnostic Trouble Codes.
Use the Ctrl+f keys to easily search for information on the page.
The first character is “System”. The first letter of the fault code identifies the system (part of the vehicle) to which the error applies.
P = Powertrain (engine and/or automatic transmission)
B = Body (airbags, central locking, power windows)
C = Chassis
U = Undefined (communication bus between electronic components)
The second character is “Code Type”. The second character indicates whether the fault code refers to a general fault type (the same for all OBD II engines), or whether it is a manufacturer-specific fault.
0 = Generic (generic code for OBD2, it is a number, not a letter)
1 = Enhanced (manufacturer-specific code)
2 = Enhanced (manufacturer-specific code)
3 = Reserve
The third digit is “Subsystem”. The third digit identifies the subsystem to which the fault applies.
1 = Emission Management (Fuel or Air)
2 = Injector Circuit (Fuel or Air)
3 = Ignition or Misfire
4 = Emission Control
5 = Vehicle Speed & Idle Control
6 = Computer & Output Circuit
7 = Transmission
8 = Transmission
9 = SAE Reserved
10 = SAE Reserved (reserve)
The fourth and fifth characters are “Error Sequence Number”. Together with the rest of the characters, they indicate the fault feature.
