2.TROUBLESHOOTING PRECAUTION
  1. When there are malfunctions in the contact points of the terminals or installation problems with any parts, removal and installation of the suspected problem parts may return the system to its normal condition either entirely or temporarily.
  2. In order to determine the location of the malfunction, be sure to check the conditions at the time the malfunction occurred through data such as DTC and freeze frame data outputs. Record this information before disconnecting any connectors and removing or installing any parts.
  3. Since the vehicle stability control system may be influenced by malfunctions in other systems, be sure to check for DTCs in other systems.
  4. Be sure to remove and install the brake actuator and each sensor with the ignition switch off, unless specified in the inspection procedures.
  5. When removing and installing the brake actuator and each sensor, be sure to check that the normal display is output during a test mode inspection and a DTC output inspection after reinstalling all the parts.
  6. After replacing the brake actuator and/or yaw rate sensor, be sure to perform yaw rate and deceleration sensor zero point calibration (RAV4_ACA30 RM000001K1O00SX.html).
  7. The CAN communication system is used for data communication between the skid control ECU, the steering angle sensor and the yaw rate sensor (the deceleration sensor is included). If there is trouble in the CAN communication line, the DTC of the communication line is output.
  8. If the DTC of the CAN communication line is output, repair the malfunction in the communication line and then troubleshoot the vehicle stability control system.
  9. Since the CAN communication line has its own length and route, it cannot be repaired temporarily with a bypass wire, etc.

3.CHASSIS DYNAMOMETER PRECAUTION
Enter Test Mode to disable TRC and VSC control when using a chassis dynamometer (RAV4_ACA30 RM0000022CZ00EX.html).
HINT:
  1. The vehicle may unexpectedly move off of the dynamometer due to TRC and VSC operation.
  2. Pressing the VSC OFF switch does not disable TRC and VSC operation completely.
NOTICE:
  1. Make sure that the slip indicator light is blinking (Test Mode is activated).
  2. Secure the vehicle with lock chains for safety.
