Intermittent ABS Light

[komichal]

Had this. Authorized shop told me that this is unfortunately common problem for Yarises 2006 and newer. The connector of the ABS wires is not well protected against water, salt etc. so it eventually corrodes so heavily that the metallic contacts basically disappear... A piece of ABS harness needs to be changed completely.
Had this like 10 years ago. The shop changed the wiring (it was not expensive) and problem solved.
