Toyota RAV4 (XA40) 2013-2018 Service Manual: Assist map number un-writing

Toyota RAV4. Assist map number un-writing


Description

The power steering ecu outputs this dtc when it determines that the assist map is not written in the ecu.

Hint:

The assist map data is written in the power steering ecu to control assisting power.

The assist map has 3 types. Select an assist map according to the vehicle country information that is recorded in the ecu.


Inspection procedure

  1. Perform assist map writing

  1. Turn the ignition switch on.
  2. Connect the intelligent tester (with can vim) to the dlc3.

Hint:

At this time, check that the p/s warning light is illuminated.

  1. Select signal check, and change to test mode.
  1. Wait for 3 seconds.


  1. Check p/s warning light

  1. Check the p/s warning light.

Result


Hint:

If the p/s warning light blinks at 0.25 Second intervals, the assist map adjustment has completed normally.



  1. Check dtc

  1. Check for dtc.

Result


Hint:

If dtc c1581/26 is output, turn the ignition switch off. Enter test mode again. If the dtc is output 3 times in a row, replace the power steering ecu.
