Engine Control Module: Testing and Inspection
Reading Diagnostic Trouble Codes
Diagnostic Modes 01 - 09
The information provided in Modes 01 through 09 displays the various levels of emission related data that may be monitored, as well as the ability
to retrieve and read stored DTC trouble codes , erase stored DTC trouble codes, generate readiness codes, and select the various PIDs and Test-IDs
used within the modes to monitor the engine, and emission related component parameters.
‹› Depending on scan tool and protocol used, the information displayed may be referred to by different names such as Test-ID (TID), Hex-ID,
Component-ID (CID), On-Board Diagnostic Monitor Identifier (OBDMID), or contain no name at all and be referenced by only a number.
Diagnostic Mode 03 - Read DTC Memory
Diagnostic Mode 03 makes it possible to read emissions-related faults (confirmed DTCs: faults which have activated the MIL) in the ECM and in the
TCM.
When the Engine Control Module (ECM) recognizes an emission related fault, it turns on the Malfunction Indicator Lamp (MIL) or if a Electronic
Throttle Malfunction is recognized, the Engine Control Module (ECM) turns on the Electronic Power Control (EPC) Warning Lamp which are both
located in the instrument cluster.
The DTCs are sorted by SAE code with the DTC tables consisting of a 5-digit alpha-numeric value.
Depending on scan tool and protocol used, the information displayed in diagnostic mode 03 may be referred to by different names such as Test-ID
(TID), Hex-ID, Component-ID (CID), On-Board Diagnostic Monitor Identifier (OBDMID), or contain no name at all and be referenced by only a
number.
The following tables provide a breakdown and explanation of the DTC code.
