Vehicle Speed
- 19 mph (30 km/h) or more.
- More than 0 mph (0 km/h) with brake pedal fully released (brake pedal position switch OFF).
- Does not exceed 7 mph (12 km/h) in forward gears.
- Does not exceed 19 mph (30 km/h) in reverse.

VEHICLE SPEED |
Transmission
- Clutch pedal is pressed during a momentary stop, and 1st gear is the probable gear selection.
- Shifter is in reverse.
- Neutral position switch signal does not turn ON/OFF after exceeding 3 mph (5 km/h).
NOTE:
- Estimation of gear selection is calculated from a engine speed and output shaft (countershaft) speed within the ECM.
- Reverse position is detected by back up light switch input signal (ON in reverse).
- Neutral position is detected by neutral position switch input signal (ON in neutral).

Brake Pedal
Brake pedal position switch signal does not turn ON/OFF after exceeding 3 mph (5 km/h).
NOTE:
Brake pedal pressing is detected by brake pedal position switch input signal (ON with pedal pressed).
|
BRAKE SWITCH |
Accelerator Pedal
Accelerator pedal is pressed (APP sensor is at least 20%). |
APP SENSOR |
Clutch Pedal
Clutch pedal position switches A and C do not switch to OPEN/CLOSED after exceeding 3 mph (5 km/h).
NOTE:
Clutch pedal position switches A and C are two input signals that detect clutch pedal pressing. (Switches are CLOSED when clutch pedal is pressed.)
