Diesel particulate filter

(DPF) regeneration

frequency

Driving conditions not

appropriate for
DPF regeneration

Carry out DPF service remedy, drive

the vehicle, preferably on a main

road or motorway, until the engine

reaches its normal operating

temperature. The vehicle should

then be driven for approximately a

further 20 minutes, preferably at a

speed of 48 km/h (30 mph) or more,

but always observing speed limits

and road conditions. Successful

regeneration of the DPF is indicated

by the warning message and AMBER

priority indicator being extinguished

from the message centre. For

additional information refer to the

owner's handbook

Pinpoint tests

CAUTION: When probing connectors to take measurements in the course of the pinpoint

tests, use the adaptor kit, part number 3548-1358-00. Failure to follow this instruction may result

in damage to the vehicle.

NOTE:

When performing voltage or resistance tests, always use a digital multimeter (DMM) accurate to

3 decimal places, and with an up-to-date calibration certificate. When 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 a fault is not present when performing the pinpoint tests, an

intermittent concern may be the cause. Always check for loose connections and corroded

terminals.
