Proposal to amend para. 3.4.1. and 3.4.4. of Annex 8 to require manufacturers to account for faults or failures with other systems involved in achieving the function of the braking system in their safety concept and analysis, and insert new para. 4.5. in Annex 6 requiring consideration of implausible wheel-speed information effects on anti-lock system operation in fault analysis. The proposal responds to a fatal collision in the United Kingdom where tyre failure and inaccurate wheel speed signals caused ABS activation that resulted in loss of braking force.
