Diagnosing EFI Problems
Your authorized Mercury MerCruiser dealer has the proper service tools for diagnosing
problems on Electronic Fuel Injection (EFI) Systems. The Electronic Control Module (ECM)
on these engines has the ability to detect some problems with the system when they occur,
and store a Trouble Code in the ECM's memory. This code can then be read later by a
service technician using a special diagnostic tool.
Diagnosing DTS Problems
Your authorized Mercury MerCruiser dealer has the proper service tools for diagnosing
problems on Digital Throttle and Shift (DTS) Systems. The Electronic Control Module
(ECM)/Propulsion Control Module (PCM) on these engines has the ability to detect some
problems with the system when they occur, and store a Trouble Code in the ECM/PCM's
memory. This code can then be read later by a service technician using a special diagnostic
tool.
Engine Guardian System
The Engine Guardian System monitors the critical sensors on the engine for any early
indications of problems. The system will respond to a problem by emitting a continuous
beep and/or reducing engine power in order to provide engine protection.
If Guardian System has been activated, reduce throttle speed. The horn will turn off when
throttle speed is within the allowable limit. Consult an authorized Mercury MerCruiser
dealer for assistance.
