- With the engine at idle, slowly turn the steering wheel and hold on full lock.
- Record the pressure reading.
- Repeat the above procedure for the other side.
- Record the pressure reading.
- With the engine at idle, release the steering wheel. The pressure should be, at or below, the pressure specified.
- Pressure outside this tolerance, indicates a fault.
- To determine if the fault is in the steering pump or the steering rack, close the test valve for a maximum of 5 seconds.
