2. CLEAR ZERO POINT CALIBRATION (for Using Techstream)
HINT:
After replacing the yaw rate and acceleration sensor (airbag sensor assembly), be sure to clear the zero point calibration data in the skid control ECU (master cylinder solenoid) and perform zero point calibration.
(a) Connect Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Operate Techstream to erase the DTCs.
(d) Perform zero point calibration of the yaw rate and acceleration sensor using Techstream.
3. PERFORM ZERO POINT CALIBRATION OF YAW RATE SENSOR AND ACCELERATION SENSOR (for Using Techstream)
HINT:
After replacing the yaw rate and acceleration sensor (airbag sensor assembly), be sure to clear the zero point calibration data in the skid control ECU (master cylinder solenoid) and perform zero point calibration.
NOTICE:
(a) Procedures for test mode.
(1) Turn the ignition switch to off.
(2) Check that the steering wheel is in the straight-ahead position.
(3) for Automatic transmission: Check that the shift lever is in P and apply the parking brake.
for Manual transmission: Check that the shift lever is in neutral and apply the parking brake.
NOTICE:
DTC C1210 and C1336 will be recorded if the shift lever is not in the P position.
(4) Connect Techstream to the DLC3.
(5) Turn the ignition switch to ON.
(6) Switch the ECU to test mode using Techstream. Enter the following menus: Chassis / ABS/VSC/TRAC / Utility / Signal Check.
(7) Keep the vehicle stationary on a level surface for 5 seconds or more.
(8) Check that the slip indicator light comes on for several seconds and then blinks in the test mode pattern (0.125 seconds on and 0.125 seconds off).
NOTICE:
The slip indicator light stay ON when obtaining the zero point.
HINT:
(9) Turn the ignition switch to off.
4. PERFORM CRAWL CONTROL CALIBRATION (for Automatic transmission)
(a) Enter test mode.
(1) Turn the ignition switch off.
(2) Connect the Techstream to the DLC3.
(3) Turn the ignition switch to ON.
(4) Turn the Techstream on.
(5) Enter the following menus: Chassis / ABS/VSC/TRAC / Utility / Test Mode.
(b) Push the ON/OFF switch and check that the crawl indicator light is on while the switch is being pushed.
*a |
Drive Monitor Switch |
*b |
ON/OFF Switch |
*c |
Speed Selector Switch |
(c) Turn the ON/OFF switch off.
(d) Set the target vehicle speed to L (low) with the speed selector switch.
(e) Set the target vehicle speed to medium-low with the speed selector switch.
(f) Set the target vehicle speed to M (medium) with the speed selector switch.
(g) Set the target vehicle speed to medium-high with the speed selector switch.
(h) Set the target vehicle speed to H (high) with the speed selector switch.
(i) Set the target vehicle speed to L (low) with the speed selector switch.
HINT:
The speed selector status is displayed on the multi-information display.
(j) Turn the ignition switch off.
(k) Check if DTC C120A is output.
HINT:
If DTC C120A is not output, calibration was performed successfully.
