What is IDA? IDA is a diagnostic program that provides: 1) DTC Analysis: IDA analyzed DTCs (currently 35) and then provides quick and easy-to-understand repair solutions 2) DPF Early Regeneration Warning: IDA also reviews the three latest DPF regeneration odometer readings in the Health Report of the applicable VIN on IDA. IDA then analyzes the distances between the three regenerations. If the average of these distances is less than 55 km for a 4HK1 (5.2L) engine, or less than 70 km for a 4JJ1 (3.0L) engine, an alert will be shown on the IDA page in the form of a red regeneration icon. This is an early warning indication that a problem may be forming in the DPF regeneration cycle. However, if the enabling criteria shown above are not met, a regeneration icon will not appear on the IDA for that particular VIN. Detailed instructions on how to use IDA are included in this bulletin.
