INSPECTION PROCEDURE
NOTICE:
HINT: Operating the ignition switch, any switches, or any doors triggers related ECU and sensor communication with the CAN. This communication will cause the resistance value to change.

Selecting conventional constant speed control mode
Constant speed control mode differs from vehicle-to-vehicle distance
control mode. When constant speed control mode is selected, your
vehicle will maintain a set speed regardless of whether or not there
are other vehicles in the lane ahead.

Starter Relay Circuit High
MONITOR DESCRIPTION
While the engine is being cranked, the positive battery voltage is applied to
terminal STA of the ECM.
If the ECM detects the Starter Control (STA) signal while the vehicle is being
driven, it determines that
there is a malfunction in the STA circuit. The ECM then il ...
