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 cancelation not intentionally made
by the driver, however, excluding cancelations 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 cancelation, of
the ASC system, the vehicle speed decreases to less than
approximately 40 + 3 km/h (24.9 + 1.9 mph), and are
erased by switching OFF the ignition'switch or the MAIN
switch. When, after the diagnosis memory has been
erased, the ECU power supply is once again switched ON,
the diagnosis output code will change to ON and OFF
signals at 0.8second intervals (as shown in the illustration
at the left) if the ECU is normal, regardless of whether or
not the system is normal.
