Toyota RAV4 Service Manual: Check mode procedure

  1. Description

  1. Check mode has a higher sensitivity to malfunctions and can detect malfunctions that normal mode cannot detect. Check mode can also detect all the malfunctions that normal mode can detect. In check mode, dtcs are detected with 1 trip detection logic.
  1. Check mode procedure

  1. Make sure that the following conditions below are met:

Toyota RAV4. Check mode procedure


  1. Battery positive voltage 11 v or more
  2. Throttle valve fully closed
  3. Transaxle in the p or n position
  4. A/c off
  1. Turn the ignition switch off.
  2. Connect the intelligent tester to the can vim. Then connect the can vim to the dlc3.
  3. Turn the ignition switch on and turn the tester on.
  4. Enter the following menus: diagnosis / enhanced obd ii / check mode.

Toyota RAV4. Check mode procedure


  1. Change the ecm to check mode. Make sure the mil flashes as shown in the illustration.

Notice:

All dtcs and freeze frame data recorded will be erased if: 1) the intelligent tester is used to change the ecm from normal mode to check mode or vice versa; or 2) during check mode, the ignition switch is turned from on to acc or off.

Before check mode, make notes of the dtcs and freeze frame data.

  1. Start the engine. The mil should turn off after the engine starts.
  2. Perform "monitor drive pattern" for the ect test (see page ax-19).

    (Or, simulate the conditions of the malfunction described by the customer.)

  3. After simulating the malfunction conditions, use the tester to check the dtc and freeze frame data.

Test mode procedure
Hint: By switching the skid control ecu from normal mode to test mode, abnormality detection sensitivity is enhanced and troubleshooting can be conducted efficiently. Perform a sensor check in test mode after the speed sensor or sensor rotor has been repaired or replaced. If the igniti ...

Stuck in deceleration sensor
Description The skid control ecu receives signals from the yaw rate and deceleration sensor via the can communication system. The yaw rate sensor has a built-in deceleration sensor and detects the vehicle's condition using 2 circuits (gl1: g sensor 1, gl2: g sensor 2). If there is t ...

General information
A large number of ecu controlled systems are used in the rav4. In general, ecu controlled systems are considered to be very intricate, requiring a high level of technical knowledge to troubleshoot. However, most problem checking procedures only involve inspecting the ecu controlled system's circ ...
