Principles of Operation
For a detailed description of the speed control system, refer to the relevant Description and Operation section in the
workshop manual.
REFER to: Speed Control - 3.2L (310-03, Description and Operation) /
Speed Control - 2.2L Diesel
(310-03B Speed Control - TD4 2.2L Diesel, Description and Operation).
Inspection and Verification
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.
1. Verify the customer concern.

DTC Index
• NOTE: If a module or component is suspect, and the vehicle remains under the Manufacturers warranty, refer to the
Warranty Policy and Procedure 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 five digit codes. Match the five digits from the
scan tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give extra
information read by the manufacturer-approved diagnostic system).
• NOTE: When performing voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal
places and with a current calibration certificate. W hen testing resistance, always take the resistance of the DMM leads into
account.
• NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
• 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.
