OPERATION
The BSW-ECU (slave) will be disabled when its internal temperature is out of the range [-40 to 85 °C (-40 to 185°F)]. It will be enabled again when the temperature is within the range.
 
 
CHECK CONDITION
When all of the conditions below are satisfied:
  • Electric motor switch is in the ON position.
  • BSW-ECU (slave) system voltage is at 9-16 volts.
 
 
DIAGNOSTIC FUNCTION AND TROUBLE JUDGMENT
The BSW-ECU (slave) will set DTC C2330 when all of the following conditions are satisfied:
  • Internal temperature in the BSW-ECU (slave) is less than -40 °C (-40 °F).
  • Internal temperature in the BSW-ECU (slave) is 85 °C (185 °F) or more.
 
 
TROUBLESHOOTING HINTS
  • Internal temperature in the BSW-ECU (slave) is high or too low.

Check again if the DTC is set in the BSW-ECU (slave).
(1)
cautionTo prevent damage to scan tool (M.U.T.-IIISE), always turn the electric motor switch to the "OFF" position before connecting or disconnecting scan tool (M.U.T.-IIISE).
Connect scan tool (M.U.T.-IIISE). Refer to "How to connect the Scan Tool (M.U.T.-IIISE) ."
(2) Erase the DTC.
(3) Turn the electric motor switch to "OFF" position and then wait for approximately 15 to 30 minutes until the BSW-ECU (slave) remains at room temperature.
(4) Turn the electric motor switch from the "OFF" position to the ON position.
(5) Check if the DTC is set.
