Checking the component

For vehicles equipped with the Blind Spot Indication System (BLIS) 

The LEDs should flash three times whenever the Blind Spot Indication System (BLIS) is activated.

Switch on the ignition to check the right and left sides.

If any LED fails to flash three times on activation, try changing the control module on that side.

If both LEDs flash three times on activation, try changing the alternator control module (ACM)

For vehicles without the Blind Spot Indication System (BLIS) 

Try changing the alternator control module (ACM).

Select the desired alternative: 

1. Change the alternator control module (ACM).

   Refer to Replacing the control module 

2. Change the left camera module (LCM) / right camera module (RCM).

   Refer to Replacing the control module
