7
F:bL
The voltage to the controller has dropped below 8 volts.
F:bH
The voltage to the controller is above 17.2 volts.
F:tP
The Throttle Position Sensor is in fault mode due to the voltage being below the
idle threshold value that was set.
F:rS
Indicates a fault in the Range Sensor (PRNDL switch or pressure switch module).
F:tL
The TFT sensor voltage is too low. A possible cause of this could be that it is
shorted to ground.
F:tH
The TFT sensor voltage is too high. The TFT sensor circuit could be open.
Hot
The temperature in the transmission is above the allowed threshold (which can be
adjusted in the tuning software).
F:OS
The Output Shaft Speed Sensor is open or missing.
F:IS
The Input Shaft (Turbine) Speed Sensor (if equipped) is open or missing.
F:C1, F:C2, F:C3, F:C4
A Checksum error has been found in the table corresponding to the number
shown. Since the calibration data could be corrupted, pressure control is disabled
and the transmission will operate at full line pressure to protect it from slippage.
CSL
Torque converter clutch slip detected when fully engaged.
