Filing in context
The ABS is the most frequently cited component category in this archive, appearing in 30 of its 4,890 filings. This filing is one of 19 Toyota notifications from 2006 in this archive. For scale, 1,292 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 10 months.
Issue
The brake system control software for the four-wheel-drive ABS (Anti-Lock Brake System) is incorrect, causing insufficient suppression of ABS activation on rough road surfaces. As a result, when the driver applies the brake at low speed on a continuous downhill rough road, stopping distance may be greater than the driver expects.
Corrective action
On all vehicles, reprogram the ABS control software with the corrected version.
