Pinpoint Tests D: Hard Steering/Lack of Assist With No DTCs

Normal Operation
The VAPS system provides power assist to steering input by multiplying the turning force applied at the steering wheel. When the vehicle is at rest or at a speed below 3.2 km/h (2 mph), the VAPS system supplies maximum assist. Between 3.2 km/h (2 mph) and 191 km/h (119 mph), power assist will decrease gradually at a calibrated rate to raise steering efforts for increased directional stability and greater road feel. Above 191 km/h (119 mph), steering assist is constant.

Possible Causes
^ Circuit 8-CE9 (WH/GN)
^ Circuit 9-CE9 (BN/GN)
^ VAPS solenoid
