BLINK CODE DIAGNOSTICS
The EC-30
™
controller provides diagnostic and configuration
functions using blink code diagnostics. When the blink code
mode is activated, the EC-30
™
controller flashes the ABS
warning lamp to communicate active fault codes, fault code
history or, ABS and ATC configurations. The blink code
diagnostics mode can also be used to reset active fault
codes. See chart 5.
The ABS warning lamp illuminates while the blink code switch
is pressed. The lamp turns off when the blink code switch
is released. The blink code switch is optional and may not
be installed on some vehicles (pin F3 of the 30-pin
connector).
Following a single display of all available messages, the
ABS warning lamp remains on for five seconds and then
returns to the normal operating mode. Fault occurrence
count information is not displayed with blink code
diagnostics.
If wheel speeds are detected during the blink code
diagnostics mode, the EC-30
™
controller exits the blink code
diagnostics and returns to the normal operating mode. The
blink code diagnostics mode can only be activated following
a power-up, where wheel speeds have not been detected.
Display Active Fault Codes
To display active fault codes, press the blink code switch
one time. Following activation, there will be a three second
delay, followed by a blink code display of all active fault
codes. See chart 7 for fault code definitions.
Display Fault Code History
To display history fault codes, press the blink code switch
two times. Following activation, there will be a three second
delay, followed by a blink code display of all history fault
codes. See chart 7 for fault code definitions.
Reset Active Fault Codes
To reset active fault codes, press the blink code switch three
times. Following activation, there will be a three second
delay, followed by a blink code message of:
1-1, (System Fully Operational - No Faults Detected)
or
A blink code display of all active fault codes.
The ABS warning lamp will stay on if active faults are still
present. See chart 7 for fault code definitions.
Resetting active fault codes with blink code diagnostics does
not clear information from the fault history. Fault history
can be retrieved by using blink code diagnostics or a
diagnostic tool.
