AFS Light

[GGH25-R]

Hi all, 

 

I have a Alphard 2013 3.5 V6 4WD 

 

My AFS light flashed on and off. I have changed the sensor on the rear axle and when the headlights turn on in the evening. It starts to flash again. 

 

Any idea what it could be? Does it need to be out into a code reader to clear any fault codes or any other ideas what else it could be will be a great help 

 

Many thanks

Donc you have a PC with Toyota Techstream ? First thing for me would be to test the AFS ECU with Techstream.

Could you confirm that you have the correct HID bulbs fitted, and not aftermarket LED ones? 

 

Some of the aftermarket 'upgrades' are heavier at the rear due to heatsinks or fans or additional cabling.

Also,  you may need to recalibrate the auto levelling. 

 

Refer to the following document for the process (The document details the function and config of the electrical systems)
