3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before
proceeding to the next step

4. Use the approved diagnostic system or a scan tool to retrieve any diagnostic trouble codes (DTCs) before moving
onto the symptom chart or DTC index.
4.
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.
• NOTE: If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior
to the installation of a new module/component.
• NOTE: 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).
• NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
• NOTE: Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.
• NOTE: 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.
The table below lists all Diagnostic Trouble Codes (DTCs) that could be logged in the Fuel Fired Booster Heater Module, for
additional Diagnosis and Testing information refer to the relevant Diagnosis and Testing Section
DTC index
For a complete list of all Diagnostic Trouble Codes (DTCs) that could be logged on this vehicle, please refer to Section
100-00. REFER to:
Diagnostic Trouble Code (DTC) Index - DTC: Auxiliary Heater Control Module (AHCM)
