TCC Solenoid circuit open
TCC pressure solenoid resistance measured too high during the power-on
solenoid check. The controller will attempt to disable the TCC solenoid until the
ignition is turned off. Refer to the data display screen in the diagnostic menu to
see the measured solenoid resistance.
EPC (PCS) Solenoid circuit open
Line Pressure Control Solenoid resistance measured too high during the power-
on solenoid check. Refer to the data display screen in the diagnostic menu to
see the measured solenoid resistance.
TPS Voltage Low; run TPS Setup
The Throttle Position Sensor is in fault mode due to the voltage being below the
idle threshold value that was set. Run TPS calibration in the setup menu.
TFT Circuit Voltage Low or Shorted
The Transmission Fluid Temperature sensor voltage is too low. A possible cause
of this could be that it is shorted to ground.
TFT Circuit Voltage High or Open
The Transmission Fluid Temperature sensor voltage is too high. The TFT sensor
circuit could be open.
Transmission is Overheating
The temperature in the transmission is above the allowed threshold (which can
be adjusted in the tuning software).
OSS Circuit Open or Sensor Missing
The Output Shaft Speed Sensor circuit is open or the sensor is missing.
ISS Circuit Open or Sensor Missing
The Input Shaft (Turbine) Speed Sensor circuit is open or the sensor is missing.
(if equipped)
OSS Sensor Signal Plausibility Error
The controller detected an unexpected value from this sensor and marked it as
faulty.
