Scan the computer for code/s and see if it comes up with something, also inspect the vehicle speed sensor and wheel sensors-let me know what you find out-

6 codes were found, C0210, C0215, U0073, B1660, U0100 & U0129. Scanned by Toyota, they cleared it and further found the ABS ECM not communicating with the Tech screen. They say to drive and see if the problem re-appears, then they will trouble shoot with the ABS module ( a $2900.00 part). The problem re-appear the next day and is still there.

The following things can caused it -Is the L/R wheel sensors, brake control actuator ECU or a wiring problem between the ECU and main body harness-most of those codes applies to the brakes except the B1660-pax side airbag-They probably have to test out the ABS module or reflash the computer-sorry this is all I have for you
