Diagnose and Fix Toyota 4Runner ABS

Toyota has issued a service bulletin T-TT-0597-20 to address Toyota 4Runner ABS codes C0226, C0236, C0246 and Co256 on 2012-20 Toyota 4Runner vehicles. Toyota refers to their ABS system as Skid Control. Toyota is finding that owners who retrofit their vehicles with aftermarket LED or HID bulbs may be causing the ABS-related trouble codes to set.

Cause of Toyota 4Runner ABS codes C0226, C0236, C0246 and Co256

LED bulbs cause ABS codes

Radiofrequency interference (RFI) caused by aftermarket LED bulbs and HID ballasts may cause electrical noise on the ground side of the skid control circuit. If you experience any of the trouble codes shown above, clear the codes and drive the vehicle with the headlights off. If the codes do not reappear, change the headlights back to the factory style.
