TB1087- DPF Diagnosis & Testing

Models: Engine applications fitted with a Diesel Particulate Filter (DPF)

Symptoms: DPF fault codes present, DPF light illuminating or flashing, vehicle experiencing performance issues.

Failure/Issue: Inability to clear DPF and related fault codes, performing DPF regenerations, misunderstanding of the DPF system and the diesel engine operation. Excessive and unnecessary DPF forced regenerations can cause additional soot and ash to remain trapped in the DPF. These particles grow and agglomerate and result in complete failure of the DPF.
