DIAGNOSIS FUNCTION
METHOD OF READING THE DIAGNOSTIC TROUBLE
CODES
When Using the Scan Tool
Connect the scan tool to the data link connector
at the
lower right of the instrument under cover, and then read the diagnostic
trouble codes.
Caution
Always turn the ignition switch off before connecti ng or
disconnecting the scan tool.
When Using a Voltmeter
Connect a voltmeter to (4) terminal and (6) termina l of the data
link connector underneath the instrument under cove r, and take
a reading of the diagnostic trouble codes from the movement of
the needle on the voltmeter.

Pause time 3Tens digitDigitsion: 2First digit
Flashing when normal
NOTE
Other diagnostic trouble codes also output as the s ame code numbers as when using the scan tool.
HOW TO ERASE THE DIAGNOSTIC TROUBLE CODES
When using the scan tool
1.Turn the ignition switch to OFF and then back to ON again.
2. Erase the diagnostic trouble codes.
3.Check to be sure that no diagnostic trouble codes e xist.
When using a voltmeter (1) Turn the ignition switch to the OFF position.
(2) After disconnecting the battery cable from the battery
terminal for seconds or more, reconnect the cable.
(3) Turn the ignition switch to the ON position, re ad the diagnostic trouble codes and check that a no rmal code
is output.
