Section 1.3 Active DDEC Diagnostic Codes

Section 1.3
Active DDEC Diagnostic Codes

To determine if any active DDEC diagnostic codes apply to the No Start condition, perform the following:‪

  1. Turn on the ignition. Plug the Diagnostic Data Reader (DDR) or theDetroit Diesel Diagnostic Link (DDDL) into the Diagnostic Connector.

    Note: Use the Pro-Link kit to connect the DDR. Use the PC card installed in the computer to connect the DDDL.

  2. Read active codes by selecting the DIAGNOSTIC CODE MENU (ACTIVE CODES) on the DDR or DDDL.
  3. For active codes not in the Gas-Specific DDEC diagnostic codes listed in Table "Gas-Specific DDEC Diagnostic Codes" or no active codes, go to Active Non-Gas Specific DDEC Diagnostic Codes. Refer to "1.3.1 Active Non-Gas Specific DDEC Diagnostic Codes" .

Active Non-Gas Specific DDEC Diagnostic Codes

Using the active Non-Gas Specific DDEC diagnostic codes, troubleshoot as follows:‪

  1. If there are no active codes, then troubleshoot the PSV operation. Refer to "1.6.1 PSV Operation Check" .
  2. If there are active Non-Gas Specific DDEC diagnostic codes, then troubleshoot those codes. Refer to the DDEC III/IV Single ECM Troubleshooting Guide 6SE497.
  3. If there are no active codes and the engine still does not start, check for Low Fuel Pressure. Refer to "1.4 Low Fuel Pressure" .
  4. If the engine starts, troubleshooting is done.

Section 1.3.2
Active Gas-Specific DDEC Diagnostic Codes

Using the active Gas-Specific DDEC diagnostic codes, troubleshoot as follows:‪
