Detroit Diesel 60 Series Engine Troubleshootingby Jeff Woodward
The Series 60 engine was introduced by Detroit Diesel to the on-highway market in 1987. Originally available as an 11.1 liter engine, the Series 60 went through many design changes during its production. New emission control laws required diesel engines to be equipped with an exhaust-gas recirculation system. The new technology also brought many challenges for technicians in their diagnosis of possible engine performance complaints. Technicians therefore often need up-to-date information on how to properly troubleshoot a Series 60 engine.
Plug the Pro-Link connector into the OBD receptacle which is located under the dashboard on the drivers side. Depending on which model truck you are diagnosing, the receptacle may be a 12-pin round or a 12-pin rectangular Deutsch connector.
Start the vehicles engine. Allow the Pro-Link a few seconds to scan the engines electronic control module. Codes will start appearing after a few moments of operation. Record both the active and inactive codes.
Refer to the Series 60 service manual for fault code interpretations. Inactive codes mean that the electronic control module has recorded certain engine faults which have been either corrected or are no longer presently causing an engine problem. Active Codes are faults that are causing an engine problem at the present time.
Troubleshoot the active codes that were found during the engine scan process. Refer to the Series 60 service manual for repair instructions.
