Inspection procedure 3
The SC warning lamp does not illuminate when the
ignition key is turned to ON (engine stopped).
Probable cause
When the ignition switch is turned on, the SC-ECU starts to communicate with
the engine-ECU or engine-A/T-ECU. Then the SC-ECU will illuminate the SC
warning lamp if the engine speed is 350 rpm or less. If the SC warning lamp
does not illuminate, the case is probably an open circuit in the SC warning lamp
power supply circuit, a blow lamp bulb or an open circuit between the SC
warning lamp and the SC-ECU.DBlown fuse

DMalfunction of the SC-ECU
NOTE
This trouble symptom is limited to cases where communication with the MUT-II is possible(SC-ECU power
supply is normal) and the diagnosis code is a normal diagnosis code.
