When did Detroit stop using the DDEC system?
More changes have been made to the DDEC systems recently, in order to increase engine efficiency and power, and as is the case with the DDEC VI, to meet new emission standards. These ECUs can be found in the later Series 60 14L applications, before the line was discontinued in 2011.
What kind of electronic control does Detroit use?
Despite its initial development for the Series 60, DDEC units are still being used in Detroit’s DD line of engines. And Detroit no longer has the the only engines on the market with ECU’s. Electronic control is the standard of modern diesel engines.
Are there different versions of the Detroit Diesel engine?
Just as Detroit released several different engines in its Series 60 line, it came out with multiple versions of the DDEC throughout the years. Various changes were made to the systems, and the different versions came to be known as DDEC I, II, III, IV, V, and so on.
Where is the serial number on a Detroit Diesel engine?
On the in-line engines, the model number and serial number are stamped on the right -hand side of the cylinder block in the upper rear corner. An example of a Series 4-53 serial number is 04DXXXXXXX.
What should the resistance be on a DDEC V?
The resistance should measure less than or equal to 1 Ω. Once a good case ground is established, keep one of the measurement probes in place and move the other probe to one of the five exposed male injector terminals on the ECM/ECU. Measure the resistance.
What was the first version of Detroit’s ECU?
The DDEC I, as you know, is the first version of Detroit’s ECU. It was a 12 volt system, two box system, with an ECM in the cab and a EDM on the engine. It controlled timing and fuel injection, as well providing better system monitoring.
What is the model number of a Detroit Diesel engine?
Model number 5043-5100 is interpreted as follows: Series 53 Engine (5), four cylinder (04), industrial, fan to flywheel (3 ), right-hand rotation with “A” accessory arrangement (5), two-valve head engine (1), and specific model Number 00 (00).
What’s the difference between DDEC and DDEC III ECM?
The ECM has more functionality and can actuate the solenoids. With the release of the DDEC III came improved horsepower. The system switched from a 12-volt to a dual-voltage ECM. It has improved adaptability as well. This version is significantly different from its predecessors.
What to do if Flash code 91 / 4 is logged?
If code 91/4 and any other codes are logged, refer to “22.3.7 Check for +5 Volts” . If code 91/3 and any other codes are logged, refer to “22.3.4 Check Throttle Position Sensor Adjustment” . Figure 1.
