Data List Reference Table
The following items can be read by the scan tool from the ASC-ECU input data.
The following items of ECU input data can be read using scan tool.
- The system is normal.DATA LIST REFERENCE TABLE
Item No. Check item Check conditions Normal conditions 01 FL wheel speed sensor Perform a test run of the vehicle. The speedometer display and the scan tool display almost agree with each other. 02 FR wheel speed sensor 03 RL wheel speed sensor 04 RR wheel speed sensor 05 Power supply voltage 10 to 18 V 07 Brake switch (input) OFF ON Undefined - 08 Lateral G sensor (+: left turn, -: right turn) Vehicle stopped (level) -0.11 to 0.11 G Running -1 to 1 G 09 G sensor (+: deceleration, -: acceleration) Vehicle stopped (level) -0.11 to 0.11 G Running -1 to 1 G 10 Master cylinder pressure (+: pressure increase, -: pressure decrease) The brake pedal is depressed.

Low Brake fluid level is higher than the "LOWER" marking. Normal Brake fluid level switch connector is not connected. Not connected 28 ASC/TCL OFF switch (ASC OFF switch) ASC is turned ON by the ASC OFF switch. ON ASC is turned OFF by the ASC OFF switch. OFF 45 SAS OK flag (Steering wheel sensor neutral point learned) The neutral point learning of the steering wheel sensor is completed. Comp The neutral point learning of the steering wheel sensor (ASC-ECU side) is not completed. Not Comp (ASC) The neutral point learning of the steering wheel sensor (steering wheel sensor side) is not completed. Not Comp (SAS) The neutral point learning of the steering wheel sensor (ASC-ECU side and steering wheel sensor side) is not completed. Not Comp 65 Engine speed When the accelerator pedal is depressed (engine started) The tachometer display and the scan tool display almost agree with each other. 66 Engine torque Increases by the amount of the brake pedal depression. 67 TP sensor (TPS) 68 Allow ESP torque request Not allowed Allow 69 Allow ESP torque request (engine) Not allowed Allow 70 Target gear Shift position; "N" range N Shift position; "D" range D Shift position; "R" range R Shift position; "P" range P Shift position; "-" range - 71 Actual gear Shift position; "N" range N Shift position; "D" range D Shift position; "R" range R Shift position; "P" range P Shift position; "-" range - 72 Master cylinder pressure offset 73 Lateral G sensor offset 86 Ignition switch Ignition switch is "ON" position ON Ignition switch is "LOCK (OFF)" position OFF 87 Ignition switch (input) Ignition switch is "LOCK (OFF)" position Lock Ignition switch is "LOCK (OFF)" position OFF Ignition switch is "ACC" position ACC2 Ignition switch is "ACC" position ACC Ignition switch is "ON" position ON Ignition switch is "START" position Start Ignition switch is "-" position - 88 Vehicle speed Perform a test run of the vehicle. The speedometer display and the scan tool display almost agree with each other. 91 Brake pressure sensor The brake pedal is depressed. ON The brake pedal is released. OFF 97 Yaw rate sensor offset 96 G sensor offset 105 Power supply voltage (input) 10 to 18 V 120 Parking brake switch (Input) When the parking brake lever is pulled up: ON When the parking brake lever is released: OFF 128 A.S.C./TCL off switch (input) When the ASC OFF switch is pressed. ON When the ASC OFF switch is not pressed. OFF - System shutdown by ECU
While ASC-ECU is disabled by the diagnostic function, the scan tool displayed data is different from the actual measurement.
