 529 OBD II Scanner User’s Manual

• 

To standardize communication procedures and protocols between the 

diagnostic equipment (Diagnostic Tools, Code Readers, etc.) and the 

vehicle’s on-board computer.

2.3 Diagnostic Trouble Codes (DTCs)

OBD II Diagnostic Trouble Codes are codes that are stored by the on-board 

computer diagnostic system in response to a problem found in the vehicle. 

These codes identify a particular problem area and are intended to provide 

you with a guide as to where a fault might be occurring within a vehicle. 

DO 

NOT

 replace parts based only on DTCs without first consulting the vehicle’s 

service manual for proper testing procedures for that particular system, circuit 

or component. 

OBD II Diagnostic Trouble Codes consist of a five-digit alphanumeric code. 
• 

The 1st character is a 

letter

 (B, C, P or U). It identifies the “main system” 

where the fault occurred (Body, Chassis, Powertrain, or Network).

• 

The 2nd character is a 

numeric digit

 (0 thru 3). It identifies the “type” of 

code (Generic or Manufacturer-Specific).

 Note: Generic DTCs are codes that are used by all vehicle manufacturers. 

The standards for generic DTCs, as well as their definitions, are set by the 

Society of Automotive Engineers (SAE).
Manufacturer-Specific DTCs are codes that are controlled by the vehicle 

manufacturers.  The  Federal  Government  does  not  require  vehicle 

manufacturers to go beyond the standardized generic DTCs in order to comply 

with the new OBD II emissions standards. However, manufacturers are free 

to expand beyond the standardized codes to make their systems easier to 

diagnose.

• 

The 3rd character is a letter or a 

numeric digit

 (0 thru 9, A thru F). It 

identifies the specific system or sub-system where the problem is located.

• 

The 4th and 5th characters are 

letters

 or 

numeric digits

 (0 thru 9, A thru 

F). They identify the section of the system that is malfunctioning.
