DIAGNOSTIC TROUBLE CODES - CODE RETRIEVAL PROCEDURE 

 

 

 

3160g 123 

 

Retrieving and using Diagnostic Trouble Codes (DTCs) for 

troubleshooting vehicle operation is only one part of an 

overall diagnostic strategy.

 

If your instrument panel indicator lights do not come on when 
you turn on the ignition, please refer to your vehicle's service 
manual. You may have problems in the car's circuitry. It is 
recommended that you fix these problems before retrieving 
DTCs from your vehicle’s computer. 

DIAGNOSTIC TROUBLE CODES 

Diagnostic Trouble Codes, or Fault Codes, can be used to identify 
engine systems or components that are malfunctioning. The computer 
records codes for the following two types of engine problems: 

„

 

"Hard" Diagnostic Trouble Codes 

"Hard" DTCs represent problems that are occurring now and cause 
the instrument panel Malfunction Indicator Lamp (MIL) or Check 
Engine light to illuminate and remain on until the failure is repaired. 
A DTC is stored in the vehicle's computer memory for each fault 
detected. A Scan Tool or Diagnostic Tool can be used to retrieve 
DTCs that are stored in the vehicle's computer memory. 

„

 

Intermittent/History DTCs 

Intermittent/History DTCs are stored in the computer's memory for 
problems that occur intermittently, or for problems that happened in 
the past but are not currently present. Intermittent DTCs may cause 
the Malfunction Indicator light to flicker or stay on until the 
intermittent malfunction goes away. However, the corresponding 
fault code will be stored in memory as a history DTC. If the 
malfunction that caused the history DTC to set does not recur within 
a predetermined length of time (usually within 40-80 ignition key 
start cycles), the computer will automatically erase the related fault 
code from its memory. 

CODE RETRIEVAL PROCEDURE 

Never

 replace a part based only on the DTC definition. 

Each DTC has a set of testing procedures, instructions and 
flow charts that must be followed to confirm the location of 
the problem. This information is found in the vehicle's service 
manual. Always refer to the vehicle's service manual for 
detailed testing instructions.
