Marine ECM Trouble Code Tool
P/N 94008
The marine Engine Control Module (ECM) continually checks the integrity of
its sensors and controls. When a problem is detected a Diagnostic Trouble
Code (DTC) is set and retained in the ECM’s computer memory. These
stored trouble codes are intended to assist a service technician in
diagnosing engine and control system problems.
This CodeMate tool provides a service technician with 3 separate diagnostic
functions. It can be used as a Malfunction Indicator Lamp (MIL), a trouble
code display & erase tool and a base spark timing tool.
CONNECTING CODEMATE
1) Turn the engine’s ignition switch to the OFF position (engine not running).
2) Locate the engine’s Data Link Connector (DLC).
3) Place CodeMate tool’s test switch in the OFF position and plug the
unit into the Data Link Connector. Be sure to slide the CodeMate tool
completely into the data connector so that the connector’s locking tab
clicks into place. With this accomplished the CodeMate unit is now
properly connected.
To clear stored trouble codes with CodeMate use the following procedure:
1) Follow the steps described in “Connecting CodeMate” to install it onto
the engine’s Data Link Connector.
2) Turn the ignition key ON but DO NOT start the engine (Key ON - Engine
Off).
3) Place the CodeMate's test switch in the ON position. This action puts
the EFI system into Service Mode
4) Move the throttle, while in neutral, from 0% to 100% then back to 0%
5) Turn the ignition key OFF for 5 seconds.
6) Perform the “Reading Stored Trouble Codes” procedure to verify that the
codes have been cleared.
7) When complete, turn the ignition key OFF and disconnect the CodeMate
tool.
Note: Always be sure that the engine’s battery is fully charged before
attempting the above procedure. A low battery may impair the ECM’s ability
to clear its stored trouble codes.
BASE SPARK TIMING FUNCTION
As a result of its ability to place the EFI system in Service Mode and also
hold the Ignition Spark Advance to a fixed value during this mode, the
CodeMate tool provides a technician with a convenient method of setting
the engine’s Base Spark Timing. The procedure requires the use of an
appropriate timing light as well as adherence to the manufacturer’s
recommended steps for this service. Please refer to the manufacturer’s
service manual for details on performing this procedure.
