Work Procedure

WARNING: This page is about a different car, the 2020 Nissan Altima. However, it is still accessible from the selected car via links, so may be relevant.

Vehicle specification needs to be written with CONSULT because it is not written after replacing sonar control unit.

Configuration has three functions as follows:

Function

Description

"Before Replace ECU"

  • Reads the vehicle configuration of current sonar control unit.
  • Saves the read vehicle configuration.

"After Replace ECU"

Writes the vehicle configuration with manual selection.

"Select Saved Data List"

Writes the vehicle configuration with saved data.

CAUTION:
  • When replacing sonar control unit, you must perform "Select Saved Data List" or "After Replace ECU" with CONSULT.
  • Complete the procedure of "Select Saved Data List" or "After Replace ECU" in order.
  • If you set incorrect "Select Saved Data List" or "After Replace ECU", incidents might occur.
  • Configuration is different for each vehicle model. Confirm configuration of each vehicle model.
  • Never perform "Select Saved Data List" or "After Replace ECU" except for new sonar control unit.
