NOTE
1. Codes indicated by the' symbol are displayed, if the conditions are satisfied, even if the system is normal.
In either case, the system is normal if it can be reset. If there is an automatic cancellation not intentionally
made by the driver, however, excluding cancellations explicitly made by the cancel procedure, there may
be a temporary malfunction such as poor contact of a harness connector even though the system can be
reset, and for that reason it is necessary to check according to each individual check chart that is applicable.
2. Diagnosis codes are displayed when, after cancellation of the ASC system, the vehicle speed decreases
to less than approximately 20 km/h (12 mph), and are erased by switching OFF the ignition switch or
the MAl N switch. After the diagnosis codes in the memory are erased, if (when the power supply of the
electronic control unit is switched ON once again) the
power supply of the electronic control unit is normal, the
diagnosis output code display will be as below, regardless
of whether the system condition is normal or not.
1) If a multi-use tester is used:
"NORMAL!!" will be displayed.
2) If a voltmeter is used:
Continuous ON/OFF signals will be displayed at
0.5-second intervals.
