Air Conditioning Control Module (ACCM)

NOTE: The ACCM  is integral to the A/C  electric compressor and cannot be serviced separately.
DTC Description Action
P0562:00 System Voltage Low: No Sub Type Information RETRIEVE and REPAIR all non-network Diagnostic Trouble Codes (DTCs) in the DC to DC Converter Control Module (DC/DC).
REFER to: DIRECT CURRENT/DIRECT CURRENT (DC/DC) CONVERTER CONTROL MODULE - HYBRID ELECTRIC VEHICLE (HEV) (414-05 Voltage Converter/Inverter, Diagnosis and Testing).
If there are no Diagnostic Trouble Codes (DTCs) in the DC to DC Converter Control Module (DC/DC), GO to PINPOINT TEST B
P0563:00 System Voltage High: No Sub Type Information REFER to: DIRECT CURRENT/DIRECT CURRENT (DC/DC) CONVERTER CONTROL MODULE - HYBRID ELECTRIC VEHICLE (HEV) (414-05 Voltage Converter/Inverter, Diagnosis and Testing).
P0AFA:16 Hybrid/EV Battery System Voltage Low: Circuit Voltage Below Threshold
P0AFB:17 Hybrid/EV Battery System Voltage High: Circuit Voltage Above Threshold
P0AFB:1C Hybrid/EV Battery System Voltage High: Circuit Voltage Out of Range
B11EE:19 A/C Compressor: Circuit Current Above Threshold
B11EE:41 A/C Compressor: General Checksum Failure RETRIEVE and REPAIR Diagnostic Trouble Codes (DTCs) in the PCM  and BECM. VERIFY the integrity of the connectors and wiring in the ACCM  (air conditioning control module) system. If no problems are found, INSTALL a new A/C  electric compressor.
REFER to: AIR CONDITIONING (A/C) ELECTRIC COMPRESSOR (412-00 Climate Control System - General Information, Removal and Installation).
B11EE:4B A/C Compressor: Over Temperature VERIFY the refrigerant charge level.
REFER to: SPECIFICATIONS (412-00 Climate Control System - General Information, Specifications).
If the charge level is low, RECHARGE the system, REFER to: AIR CONDITIONING (A/C) SYSTEM RECOVERY, EVACUATION AND CHARGING (412-00 Climate Control System - General Information, General Procedures).
CLEAR the Diagnostic Trouble Codes (DTCs). CYCLE ignition. OPERATE the system on MAX A/C  for 5 minutes, then REPEAT the self-test. If the DTC  returns, INSTALL a new A/C  Electric Compressor.
REFER to: AIR CONDITIONING (A/C) ELECTRIC COMPRESSOR (412-00 Climate Control System - General Information, Removal and Installation).
B11EE:92 A/C Compressor: Performance or Incorrect Operation GO to PINPOINT TEST I
U0001:88 High Speed CAN Communication Bus: Bus off The module could not communicate on the network at a point in time. The fault is not currently present (the module had to communicate with the scan tool to report this DTC  . VERIFY the integrity of the connectors and wiring.
U0140:00 Lost Communication with Body Control Module: No Sub Type Information GO to PINPOINT TEST D
U0293:00 Lost Communication with Hybrid/EV Powertrain Control Module: No Sub Type Information GO to PINPOINT TEST V
U0422:00 Invalid Data Received From Body Control Module: No Sub Type Information RETRIEVE and REPAIR all non-network Diagnostic Trouble Codes (DTCs) in the BCM  .
REFER to: BODY CONTROL MODULE (BCM) (419-10 Multifunction Electronic Modules, Diagnosis and Testing).
U3000:04 Control Module: System Internal Failure INSTALL a new A/C  electric compressor.
REFER to: AIR CONDITIONING (A/C) ELECTRIC COMPRESSOR (412-00 Climate Control System - General Information, Removal and Installation).
U3000:42 Control Module: General Memory Failure CLEAR the Diagnostic Trouble Codes (DTCs). CYCLE ignition. OPERATE the system on MAX A/C  for 5 minutes, then REPEAT the self-test. If the DTC  returns, INSTALL a new A/C  Electric Compressor.
REFER to: AIR CONDITIONING (A/C) ELECTRIC COMPRESSOR (412-00 Climate Control System - General Information, Removal and Installation).
U3000:49 Control Module: Internal Electronic Failure INSTALL a new A/C  electric compressor.
REFER to: AIR CONDITIONING (A/C) ELECTRIC COMPRESSOR (412-00 Climate Control System - General Information, Removal and Installation).
