2-2-3. Flash out of fault codes
Fault codes can be accessed in at least two different ways; using the electronic service tool or fault code flash out.
Fault flash out mode can be entered through the use of a diagnostic switch. The diagnostic switch may also be
multiplexed on the J1939 datalink.
Entering diagnostic mode:
1) To enter the fault flash out, the starter switch must be ON with the engine not running.
2) when a diagnostic switch is used to enter the mode, the ECM will automatically flash the first fault code
after the switch is turned on. Each active fault shall flash out twice, wrapping around to the first fault
code at the end.
Flashing of fault codes:
The diagram below depicts the pattern of the fault code flash out scheme as indicated by the “ENGINE
STOP” lamp. A blink is equivalent to the “ENGINE STOP” lamp being on for 0.5 seconds, and off for 0.5
seconds. A pause between fault code digits has duration of 2 seconds.
