MFD Blink Codes
The check engine LED will display a blink code whenever the
ECU determines there is a problem with one or more of the
sensors. Use Digital Wrench to troubleshoot, fix and clear the
codes.
When a blink code is displayed, the CHECK ENGINE light will
illuminate for 1/2 second “on” and 1/2 second “off” with a 1
second “off” interval between close.
DTC Troubleshooting
Always use the Digital Wrench diagnostic software program to
troubleshoot DTCs, MFD blink codes, and overall performance
problems.
Digital Wrench can be used to display trouble codes and offers
guided diagnostics. Guided diagnostics allows the technician to
perform diagnostic checks in an attempt to isolate the root
problem.
1. To access trouble codes, click on the “!” button. If any
codes are listed, select a code to proceed.
2. To access guided diagnostics, click on the “SPECIAL
TESTS” (toolbox) button. Then click “DIAGNOSTIC
PROCEDURES”.
3. Select a code or system in the ‘SYSTEM CHARTS” menu.
A description of the DTC or system will be displayed.
4. Click on (A) to activate guided diagnostics.
5. Click on (B) to view a wiring schematic of the component
or system.
6. Click on “X” to exit the current screen.
