Honda HR-V: Steering Column - Inspection & Adjustment

DESCRIPTION

EPS SYSTEM DESCRIPTION - STEERING COLUMN

The steering force from the steering wheel is sent to the column shaft. The torque sensor measures the difference between the force applied to the column shaft and the resistance to turning the wheels due to road friction, and converts it to a voltage signal which is sent to the EPS control unit. Based on this signal, the EPS control unit controls the current to the EPS motor. The EPS motor rotates the worm gear which is engaged to the worm wheel gear which is part of the column shaft. This becomes the assist force in the steering system.

INSPECTION & ADJUSTMENT

STEERING COLUMN INSPECTION

Inspection

1. Check of Tilting Force

1. Set the steering wheel in the straight ahead driving position, and loosen the lock lever fully
2. Attach a commercially available spring scale (A) to the highest point of the steering wheel, and tilt the steering column to the lowest position
3. Pull the spring scale straight up, and read the force required to move the steering column
4. Attach the spring scale to the lowest point of the steering wheel
5. Pull the spring scale straight down, and read the force required to move the steering column.

Tilting force (upward/downward):

Standard: 69 N (7.0 kgf, 15.5 lbf) max.

6. If the measurement is higher than specified, replace the steering column.

2. Check of Telescoping Force

1. Set the steering wheel in the straight ahead driving position, and loosen the lock lever fully.
2. Attach a commercially available spring scale (A) to the center point of the steering wheel as shown.
3. Pull the spring scale, and read the force required to move the steering column during telescoping out.

Telescoping force:

Standard: 90 N (9.2 kgf, 20.2 lbf) max.

4. If the measurement is higher than specified, replace the steering column.

3. Check of Lock Lever Force

1. Move the lock lever (A) from the loosened position to the locked position three to five times, then release the lock lever. Adjust the steering column to the center tilt position and also to the full telescopic out position, and hold the steering wheel
2. Using a commercially available push-pull gauge, push up the lock lever 10 mm (0.39 in) in from its end, and measure the force required to move the lock lever.

Lock lever force:

Standard: 82 N (8.4 kgf, 18.4 lbf) max.

3. If the measurement is higher than specified, replace the steering column.

Steering Column Inspect

4. Steering Column/EPS Control Unit - Remove

5. Steering Column - Inspect

• Check the column shaft bearing (A) for play and proper movement. If bearing is noisy or has excessive play, replace the steering column/EPS control unit.
• Check the steering joint bearings (B) for play and proper movement. If any bearing is noisy or has excessive play, replace the steering shaft.
• Check the tilt mechanism for movement and damage.
• Check the telescopic mechanism for movement and damage.
• Check the sliding capsules (C) for distortion or breakage. If there is distortion or breakage, replace the steering column/EPS control unit.
• Apply multipurpose grease to the steering column.

NOTE: Do not use silicone grease.
