DIAGNOSIS TABLE

Condition
Main switch indicator
lamp fails to light up
or remains ON.
"CRUISE" indicator
lamp fails to light up or
remains ON.
When the throttle opening for the vehicle speed exceeds the specified value
during cruise control, the cruise control module sends this signal to PCM. PCM
uses this signal as one of signals to control 4-A/T.
In the state with the ignition switch ON and the cruise control system OFF,
pressing this switch once and releasing it will activate the cruise control system
and the cruise control module will cause the indicator lamp to light up.
It lights up when cruise control (accelerator pedal control) is functioning.
