General Information - Diagnostic Trouble Code (DTC) Index V8 S/C 5.0L
Petrol, DTC: Engine Control Module (ECM)
Description and Operation
Engine Control Module (PCM) 5.0L SC V8 - AJ133
WARNING: Fuel injector voltage will reach 65 Volts during operation and have a high current requirement.
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 the 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 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 additional information
read by the manufacturer-approved diagnostic system).
When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal
places, and with an up-to-date calibration certificate. When testing resistance, always take the resistance of the DMM leads
into account.
Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
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 electronic engine control module, for
additional diagnosis and testing information refer to the relevant diagnosis and testing section.
For additional information, refer to: Electronic Engine Controls (303-14 Electronic Engine Controls - V8 S/C 5.0L Petrol,
Diagnosis and Testing).

Rear Suspended Tow
When the vehicle is being recovered by rear suspended tow:
The ignition key must be removed from the ignition switch to lock the steering.
The rear wheels must be correctly positioned in the lifting cradle and securely tied down.
Emergency Towing
WARNING: If the engine is not running, the steering will become heavy and the force necessary to effectively apply the
brakes will be greatly increased.
CAUTION: A vehicle with a defective transmission must be towed by rear suspended tow.
When the vehicle is being towed on its own wheels:
Local regulations for the towing of vehicles must be followed. In some countries the registration number of the towing
vehicle and an 'On Tow' sign or warning triangle must be displayed at the rear of the towed vehicle.
The gear selector lever must be in Neutral.
The ignition switch must be in position II to release the steering lock and make the direction indicators, horn and stop
lamps operate.
A distance of 0,8 km (0.5 mile) must not be exceeded.
A speed of 48 km/h (30 mph) must not be exceeded.
The tow rope must be attached to the front towing eye. www.JagDocs.com
