DTC B1477/77 A/C Inverter Low Voltage Power Resource System Malfunction

DESCRIPTION

DTC Detecting Condition:

The w/ motor compressor assembly monitors the controlling power voltage in the circuit. It stops the compressor circuit and outputs the DTC when the monitored voltage is outside the specified range. The output DTC is memorized as previous trouble. The compressor control may not resume unless the ignition switch is turned off.

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 5 minutes after the service plug grip is removed.

Step 1-2:
