TDC Offset Learn Procedure (6.5L Diesel)

PCM will automatically activate TDC offset program when engine coolant is greater than 170°F (77°C) and engine speed is 900 RPM or less. A momentary engine stumble will occur once engine has reached desired temperature and RPM. This is an indication that PCM auto learn function has been activated. If offset is programmed out of range, DTC P1214 will set.
