Section 9.1
Description of PID 103 – Turbo No Revolution Fault

PID 103 indicates that the PLD-MR has not received a turbo speed monitoring signal from the Turbo Speed Sensor (TSS). ‪

Certain engines equipped with a turbo brake require turbo speed monitoring during the braking mode in order to control engine brake power. The speed is controlled through the TSS installed on the turbo shaft housing. See Figure "Turbo Speed Sensor Location" . PID 103 is logged when the PLD-MR on the engine fails to receive the monitoring signal from the sensor.‪
