Manufacturer summary

Original wording in English

SB-17-013 CHARGE AIR COOLER (CAC) INSPECTION P0299 P226C -- In the event that a subject vehicle exhibits low power with DTC (Diagnostic Trouble Code) P0299 (underboost) and/or P226C (boost pressure slow response), inspect the CAC (Charge Air Cooler) for any ruptured tubes before performing in depth diagnostics on the intake system. A ruptured CAC will result in low boost. Operating the engine with low boost for extended periods can eventually cause damage to the DPF (Diesel Particulate Filter). Inspection of the DPF may be necessary if the engine still has low power, or is not completing regeneration properly after replacing a ruptured CAC. Soot accumulation on the tailpipe may also indicate that the DPF has been damaged.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
