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

Tests D1 - D2:

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
