DATA LIST REFERENCE TABLE
 
 
The following items of ECU input data can be read using scan tool.
1.
Item No.Check itemCheck conditionNormal condition
01FL wheel speed sensorPerform a test run of the vehicle.The speedometer display and the scan tool display almost agree with each other. <During stop: approximately 0.4 mph (0.7km/h)>
02FR wheel speed sensor
03RL wheel speed sensor
04RR wheel speed sensor
05Power supply voltageBattery positive voltage (10 to 18 V ASC operable range)
07Brake switch (input)The brake pedal is depressed.ON
The brake pedal is released.OFF
08Lateral G sensor (+: left turn, -: right turn)Vehicle stopped (level)-0.11 to 0.11 G
Running-1 to 1 G
09G sensor (+: deceleration, -: acceleration)Vehicle stopped (level)
  • 0 G*1 (fixed value)
    <Vehicles with FWD>
  • -0.11 to 0.11 G
    <Vehicles with AWD, FWD with idle neutral control>
RunningFWD0 G*1 (fixed value)
AWD-1 to 1 G
10Master cylinder pressure (+: pressure increase, -: pressure decrease)The brake pedal is depressed.Increases by the amount of the brake pedal depression.
The brake pedal is released.-3 to 3 bar
11Steering angle (+: left turn, -: right turn)Vehicle stopped (the steering wheel is in the neutral position)-6 to 6 deg
RunningNearly the same as the steering wheel operation angle <-720 to 720 deg (ASC-ECU normal detection value)>
Nearly the same as the steering wheel operation angle <-850 to 850 deg (Sensor normal value as a single unit)>
12Yaw rate sensor (+: left turn, -: right turn)Vehicle stopped (level)-3.6 to 3.6 deg/s
Running-100 to 100 deg/s
14Brake switchThe brake pedal is depressed.ON
The brake pedal is released.OFF
15Emission test modeEmission test mode: ONON
Emission test mode: OFFOFF
26Brake fluid pressure switchBrake fluid level is lower than the "LOWER" marking.Low
Brake fluid level is higher than the "LOWER" marking.Normal
28A.S.C./TCL off switchWhen the ASC OFF switch is not operated (when the ASC control is available)ON
When the ASC OFF switch is operated (pressed and held for 3 seconds or more)(when the ASC control is prohibited)OFF
When the ASC OFF switch is operated (pressed and held for 15 seconds or more)(when the ASC OFF control is prohibited by fail-safe function)*2ON
45SAS OK flagWhen the steering wheel sensor neutral point is learnedComp
When the steering wheel sensor neutral point is not learnedNot Comp
When the steering wheel sensor is defectiveSAS fail
SAS fail&No Comp
65Engine SpeedWhen the accelerator pedal is depressed (engine started)The tachometer display and the scan tool display almost agree with each other.
66Engine torqueDisplays the engine torque.
67APSDisplays the accelerator pedal opening angle.
68Allow A.S.C. torque requestPermitted
70Target gearWhen the selector lever is operatedDisplays the selector lever position.
71Actual gear
72Master cylinder pressure OffsetThe difference between the neutral position that was input to the ASC-ECU before the master cylinder pressure sensor calibration and the neutral position after the calibration.-8 to 8 bar
73Lateral G sensor offsetThe difference between the neutral position that was input to the ASC-ECU before the G and yaw rate sensor calibration and the neutral position after the calibration.-0.15 to 0.15 G
86Ignition switchIgnition switch: ONON
87Ignition switch (input)Ignition switch: ONON
88Vehicle speedPerform a test run of the vehicle.The speedometer display and the scan tool display almost agree with each other.
91Brake pressure sensorThe brake pedal is depressed.ON
The brake pedal is released.OFF
96G sensor offsetThe difference between the neutral positions before the calibration and after the calibration received in the ASC-ECU at G & yaw rate sensor calibration.
  • 0 G*1 (fixed value)
    <Vehicles with FWD>
  • -0.15 to 0.15 G
    <Vehicles with AWD, FWD with idle neutral control>
97Yaw rate sensor offsetThe difference between the neutral position that was input to the ASC-ECU before the G and yaw rate sensor calibration and the neutral position after the calibration.-6.0 to 6.0 deg/s
105Power supply voltage (input)Battery positive voltage (10 to 18 V ASC operable range)
120Parking brake switch (Input)When the parking brake lever is pulled up:ON
When the parking brake lever is released:OFF
128A.S.C./TCL off switch (input)The ASC OFF switch is pressed.ON
The ASC OFF switch is not operated.OFF
note
  • *1: The G and yaw rate sensor does not detect longitudinal acceleration of a vehicle, thus "0 G" is always set.
  • *2: When the ASC OFF switch is pressed and held for 15 seconds, the ASC system returns to the ON status.
