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.

Starter Motor Will Not Crank Engine, Or Cranks Slow

Possible Cause

Remedy

Battery switch turned off.

Turn the switch on.

Remote control not in neutral position.

Position the control lever in neutral.

Open circuit breaker or blown fuse.

Check and reset the circuit breaker or replace fuse.

Loose or dirty electrical connections or damaged

wiring.

Check all electrical connections and wires (especially

battery cables). Clean and tighten all faulty

connections.

Bad battery or low battery voltage.

Test the battery and charge if necessary; replace if

bad.

Lanyard stop switch activated.

Check the lanyard stop switch.
