Section 211 (Starting System - Diesel): Description
The starter used on the 6.0L turbo diesel engine uses internal gear reduction and an externally mounted solenoid. System consists of a starter, ignition switch, starter relay, Digital Transmission Range (DTR) sensor, 2 batteries and wiring.
The DTR sensor assembly is an internally mounted sensor, located next to the solenoid body, and includes the detent spring, rooster comb, and bracket. The sensor is non-adjustable and is serviced as an assembly. The sensor contains electronic circuitry that provides the PCM a fixed frequency at a duty cycle for each of the various positions of the manual lever (Park, Reverse, Neutral, etc.). The PCM uses the sensor signal for engine functions (start, reversing lamps) and for line pressure control, shift scheduling, and TCC operation.
