General Information - Diagnostic Trouble Code (DTC) Index DTC: Climate
Control Module (HVAC)
Description and Operation

Climate Control Module


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
NOTES:


If a control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty
Policy and Procedures manual, or determine if any prior approval programme is in operation, prior to the installation of a new
module/component.


Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to
the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the
manufacturer-approved diagnostic system).


When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places, and with
an up-to-date calibration certificate. When testing resistance always take the resistance of the digital multimeter leads into
account.


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.


Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.


If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.


Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as required.

The table below lists all Diagnostic Trouble Codes (DTCs) that could be logged in the Climate Control Module. For additional
diagnosis and testing information, refer to the relevant Diagnosis and Testing section in the workshop manual.
For additional information, refer to: Climate Control System (412-00 Climate Control System - General Information, Diagnosis and Testing).

A/C Refrigerant
Pressure - Signal
below allowable
range
Signal below allowable
range. A/C System
Refrigerant Pressure
too low
This DTC can be logged by the system due to low ambient
temperature soak (below 3°C) reducing the pressure in the
refrigerant gas system. If the cabin temperature logged
along with the DTC at the time is below 10°C this could
indicate low temperature. If the air conditioning
performance is satisfactory and the in-cabin temperature is
below 10°C then it is likely that the system contains a
suitable amount of gas and the DTC is being recorded as
an effect of the low ambient temperature. If this is not the
case carry out any pinpoint tests associated with this DTC
using the manufacturer approved diagnostic system. Refer
to the electrical circuit diagrams and check air conditioning
pressure sensor circuits for short, open circuit. Check for
correct charge weight B11FF-85
