Some customers may comment on a Service Engine Soon Light / Check Engine Light
on. Upon inspection technicians may nd DTCs P0101, P0299, P0712, P11CC, P11DC,
P2002, P2463, P2627, P2A00, P2459, P22B6, P200C, P200E, P0263, P0266, P0269,
P0272, P0275, P0278, P0281 and/or P0284 set.
These DTCs may be the result of loose connections of the charge air cooler
ductwork.
Correction:
If any combination of DTCs DTCs P0101, P0299, P0712, P11CC, P11DC, P2002, P2463, P2627, P2A00, P2459, P22B6,
P200C, P200E, P0263, P0266, P0269, P0272, P0275, P0278, P0281 and/or P0284 are set; check for loose charge air
cooler ductwork at the turbocharger outlet pipe, the charge air cooler inlet pipe, the charge air cooler outlet pipe
and the connection at the intake air ow valve (throttle body).
Please note that a static visual inspection may not reveal that the connection is not adequate and that it is most
likely to occur during engine roll or brake torque. It is highly recommended to test for leaks in the charge air
cooler system by using the procedure found in Service Information Document ID: 4282009 (Charge Air Cooler
Diagnosis)
Check for non-secured connection of the charged air cooler pipe at the intake air ow valve (throttle body).
Check for proper alignment of the charged air cooler pipe bracket and bolt hole.
Non-secured connection.
Mis-aligned charged air cooler pipe bracket and bolt hole after the charge air cooler outlet hose is connected
properly to the throttle body.
If P2463 was not set and a charge air cooler leak or disconnect was found, after repairing charge air cooler
connections, command Diesel Particulate Filter (DPF) Regeneration Enable with the scan tool before returning the
vehicle to the customer.
If P2463 was set refer to the service information Document ID: 4581477
Note: This will put the vehicle in DPF regen mode when the customer gets the vehicle, delaying any emissions
diagnostic codes that can be fouled by high soot in the exhaust, until the exhaust is cleaned by the customer
driving with an on-road DPF regeneration.
