Subject:
LOADED I/M TEST FOR NON-SWITCHABLE TRACTION CONTROL VEHICLE

Some provincial Inspection/Maintenance (I/M) programs require a loaded mode test conducted on a dynamometer. A loaded mode test using a 2WD dynamometer cannot be performed on vehicles with full time four wheel drive or "non-switchable" traction control vehicles. A list of these vehicles is provided below for 2001 models.

The "CENTER DIFFERENTIAL LOCK" switch on the 2001 4Runner 4WD and the "VSC OFF" switch on the 2001 4Runner 4WD and Sequoia 4WD models do not deactivate traction control action. There is no combination of switch setting and 2WD/4WD selector position that can achieve deactivation of traction control on these models. Therefore, the 2001 4Runner 4WD and Sequoia 4WD are non-switchable traction control types and cannot be tested on 2WD dynamometer without special service procedures inappropriate for I/M use.
