Air Conditioning Compressor Module (ACCM) DTC Chart

WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: This module utilizes a 5-character DTC followed by a 2-character failure type code. The failure type code provides information about specific fault conditions such as opens or shorts to ground. Continuous Memory Diagnostic Trouble Codes (CMDTCs) have an additional 2-character DTC status code suffix to assist in determining DTC history.

NOTE: Some PCM DTCs may inhibit A/C operation. If any PCM DTCs are retrieved, diagnose those first. Refer to the PCM DTC CHART .

ACCM DTC CHART

DTC	Description	Action to Take
P0AFA:16	Hybrid Battery System Voltage Low: Circuit Voltage Below Threshold	GO to PINPOINT TEST J .
P0AFB:17	Hybrid Battery System Voltage High: Circuit Voltage Above Threshold	GO to PINPOINT TEST J .
B11EE:19	A/C Compressor: Current Above Threshold	INSTALL a new electric A/C compressor. REFER to REMOVAL AND INSTALLATION . TEST the system for normal operation.
B11EE:49	A/C Compressor: Internal Electronic Failure	INSTALL a new electric A/C compressor. REFER to REMOVAL AND INSTALLATION . TEST the system for normal operation.
B11EE:4B	A/C Compressor: Over Temperature	VERIFY the refrigerant charge level. REFER to SPECIFICATIONS in this section. If the charge level is low, RECHARGE the system, CLEAR the DTCs and REPEAT the self-test. TEST the system for normal operation. If the DTC returns, INSTALL a new electric A/C compressor. REFER to REMOVAL AND INSTALLATION . TEST the system for normal operation.
U0100:00	Lost Communication With ECM/PCM "A": No Sub Type Information	REFER to PINPOINT TEST A: THE PCM DOES NOT RESPOND TO THE SCAN TOOL to diagnose lost communication with the ECM/PCM "A".
U0155:00	Lost Communication With Instrument Panel Cluster (IPC) Module: No Sub Type Information	REFER to PINPOINT TEST C: THE INSTRUMENT CLUSTER (IC) DOES NOT RESPOND TO THE SCAN TOOL to diagnose lost communication with the IPC module.
U0401:68	Invalid Data Received From ECM/PCM "A": Event Information	This DTC can set due to a fault in the PCM or because the PCM is unable to communicate over the Controller Area Network (CAN) bus. CARRY OUT a self-test of the PCM. If the scan tool indicates that the PCM is not responding, REFER to PINPOINT TEST A: THE PCM DOES NOT RESPOND TO THE SCAN TOOL to diagnose the network communication concern. If PCM DTCs are present, REFER to the INTRODUCTION - HYBRID .
U0423:68	Invalid Data Received From Instrument Panel Cluster Control Module: Event Information	This DTC can set due to a fault in the Instrument Panel Cluster (IPC) or because the IPC is unable to communicate over the CAN bus. CARRY OUT a self-test of the IPC . If the scan tool indicates that the IPC is not responding, REFER to PINPOINT TEST C: THE INSTRUMENT CLUSTER (IC) DOES NOT RESPOND TO THE SCAN TOOL to diagnose the network communication concern. If IPC DTCs are present, REFER to DTC CHARTS to diagnose the IPC system fault.
U3000:49	Control Module: Internal Electronic Failure	INSTALL a new electric A/C compressor. REFER to REMOVAL AND INSTALLATION . TEST the system for normal operation.
