DIAGNOSTICS USING “BLINK
CODES”
To enable the blink codes, turn the ignition from
’off’ to ’on’ 3 times, leaving it ’on’ the 3rd time,
within 5 seconds.
Any “blink codes” stored in the ECU will display, one at
a time, in numerical order. The word END will display
after all codes have been transmitted.
NOTE: To clear codes manually, disconnect the
positive battery lead for 20 seconds.
