Even after the trouble areas are repaired, the abs warning light will not go off unless the following operations are performed.

  1. Drive the vehicle at 20 km/h (12 mph) for 30 seconds or more and check that the abs warning light goes off.
  2. Clear the dtc(s).
  1. Keep the vehicle stationary for 5 seconds or more and depress the brake pedal lightly 2 or 3 times.
  2. Drive the vehicle at a vehicle speed of 50 km/h (31 mph) and keep depressing the brake pedal firmly for approximately 3 seconds.
  3. Repeat the above operation 3 times or more and check that the abs warning light goes off.
  4. Clear the dtc(s).

Toyota RAV4. Diagnostic trouble code chart


Description

The speed sensors detect the wheel speeds and send appropriate signals to the skid control ecu.

Speed sensor rotors have rows of alternating n and s magnetic poles, and their magnetic fields change as the rotors turn.

The speed sensors detect those magnetic changes and send pulse signals to the skid control ecu. The ecu monitors the wheel speeds through these pulse signals to control the abs control system.

Dtcs c1271/71, c1272/72, c1275/75 and c1276/76 can be deleted when the speed sensor sends a vehicle speed signal or the test mode ends. Dtcs c1271/71, c1272/72, c1275/75/75 and c1276/76 are output only in the test mode.

Inspection procedure

Notice:

Check the speed sensor signal in test mode after cleaning or replacement (see page bc-28).

  1. Check harness and connector (momentary interruption)

  1. Using the data list of the intelligent tester, check for any momentary interruption in the wire harness and connector corresponding to a dtc (see page bc-23).

Toyota RAV4. Check harness and connector (momentary interruption)


Ok: there are no momentary interruptions.

Hint:

Perform the above inspection before removing the sensor and connector.



  1. Read value of data list (front speed sensor)

  1. Check the data list for proper functioning of the front speed sensor.

Toyota RAV4. Read value of data list (front speed sensor)


Ok: there is almost no difference between actual wheel speed and displayed speed value.

Hint:

There is a tolerance of +-10% in the speedometer indication.



  1. Perform test mode inspection (signal check)

  1. Perform a test mode inspection and check for dtcs (see page bc-28).
