To display history DTC codes, press the blink code switch two times.
Following activation, there will be a 3 second delay followed by a blink
code display of all history DTC codes.

To reset active DTC codes, press the blink code switch three times.
Following activation, there will be a 3 second delay followed by a blink
code message of:
1-1, (System Fully Operational - No DTCs Detected)
or,
A blink code display of all active DTC codes.

The ABS warning lamp will stay on if active DTCs are still present.

Resetting active DTCcodes with blink code diagnostics does not clear
information from DTC history. DTC history can be retrieved by using
blink code diagnostics or by using a diagnostic tool.

Display Active DTC
Codes
To display active DTC
codes, press the blink
code switch one time.
Following activation,
there will be a 3 second
delay followed by a
blink code display of all
active DTC codes.

To check the ECU
configuration, press the
blink code switch four
times. Following
activation, there will be
