Overview:Fault Code 51 indicates an electrical failure of the Rail Select Sensor on the Electric Shifter. Detection:Starting at key on and throughout operation, the Transmission Controller constantly monitors the feedback from the sensor. If the feedback is below 10% or above 90% of the full value of the sensor, the fault code is set. This type of failure represents a short to ground or battery. The Transmission Controller also monitors the sensor feedback for a 0 value, indicating an open circuit. Fallback:This fault causes an in-place fallback. Possible Causes:1) Transmission Harness2) Rail Select Sensor3) Transmission Controller Shop Talk:Key on. If...

Overview:Fault Code 52 indicates an electrical failure of the Gear Select Sensor on the Electric Shifter. Detection:Starting at key on and throughout operation, the Transmission Controller constantly monitors the feedback from the sensor.

Overview:Fault Code 56 indicates an electrical problem in the Input Shaft Speed Sensor circuit. The signal from the sensor did not match the current operating conditions. Detection:A Speed Sensor is determined faulty when all the Speed Sensor readings are compared and at least one sensor is inconsistent. Fallback:This fault causes an in-place fallback. If the Input Shaft Speed Sensor fails before power up, the transmission is unable to engage a gear and the fault code cannot be reproduced. Possible Causes:1) Transmission Harness2) Input Shaft Speed Sensor3) Various Transmission Components4) Transmission Controller Shop Talk:Select a forward gear and drive at a...
