Transaxle selector switch position. If selector switch is OK will read P, 
R, N, D, 3, or 2. If switch is disconnected will read OPEN. If all inputs 
are grounded the readout will read GRDED. If there is an invalid 
combination of open or grounded circuits from the switch this readout 
will display INVALID.

Displays PERF/NORM status. This is the input signal from the 
PERF/NORM switch. The circuit is grounded when PERF mode is 
selected.

Displays ON/OFF indicates if brake pedal is being depressed. When 
the brake is depressed this circuit should open and the readout should 
go to ON.

Voltage available to the ignition switch input of the PCM.

Counter used by the TC to indicate a gear fault during a shift. Counter 
indicates the oncoming gear is not available. If this number is 
incrementing it indicates a fault is being detected. When a calibrated 
time is reached a DTC or information flag will set.

The ratio fail counter is used when the present gear (steady state) is 
being detected as failed. If this number is incrementing it indicates a 
failed gear is being detected. When a calibrated time is reached a DTC 
or information flag will set.

Indicates if turbine speed signal noise is being detected. Noise can be 
caused by extra pulses or missing pulses.

Indicates if vehicle speed signal noise is being detected. Noise can be 
caused by extra pulses or missing pulses.

This value is the number of times the EEPROM has been written to.

This parameter is a calculated value of the grade which the vehicle is 
currently going up or down. This parameter is used to determine if an 
upshift or down shift should occur.

This indicates what gear the PCM/TC is commanding to provide 
engine braking.

This indicates what gear the PCM/TC is commanding to help prevent 
shift busyness when going up a hill.

Indicates the amount the engine is broken in. Should read 100% after 
approximately 1000-1500 miles.
