B2644
B2643, B2644 ELECTRIC COMPRESSORDescription
The inverter in the electric compressor outputs high-voltage to operate the motor. If there is an open or short in the output circuit, the inverter in the electric compressor will stop compressor operation and output the DTC. The output DTC will be memorized as a past and present DTC. 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.
