B2641
B2640, B2641, B2642 ELECTRIC COMPRESSORDescription
The inverter monitors power voltage from the main battery in the circuit. It stops compressor control and outputs the DTC when the monitored voltage is outside the specified range. The output DTC of B2640 and B2641 are memorized only present trouble. On B2642, compressor control may not resume unless the ignition switch is turned OFF and waiting for 10 minutes.
CAUTION:
- Wear electrically insulated gloves and pull out the service plug grip before inspection as procedures may require disconnecting high-voltage connectors. Be sure to carry the removed service plug grip because other workers may install it by mistake.
- Do not touch the high-voltage connectors or terminals for 10 minutes after the service plug grip is removed.
NOTE: The hybrid control system and air conditioning system output DTCs separately. Inspect DTCs following the flow chart for the hybrid control system first if any DTCs from those systems are output simultaneously.
