Sargeant was sent skidding off the track at Sakhir last weekend after the brake bias moved unexpectedly and caused him to lock up.
Williams revealed afterwards that the problem had been caused by the brake bias changing in a way that had not been requested.
Team principal James Vowles told Autosport: “With Logan, we have an uncommanded brake bias movement all the way to the front, which is why he went off. The brake bias moved nowhere near where he requested it to be.”
Speaking ahead of the Saudi Arabian GP, Sargeant said the problem had been traced back to an ‘electronic issue’ related to the team’s change of steering wheel design for this year.
“There is a short-term fix for here and a permanent long-term fix coming in Melbourne,” he said.
Sargeant revealed that the problem had actually first come to light in qualifying in Bahrain.
“It wasn’t out of the blue,” he explained about the race issue. “We had the same problem in the second run of quali, but not to the same extent. We obviously thought we fixed it. We didn't. But certainly, it is fixed for this weekend.”
