Initial Inspection and Diagnostic Overview

Inspection and Verification

Caution:
^ Do not hold the steering wheel at the stops for an extended amount of time. Damage to the power steering pump can result.

Note:
^ Make the following preliminary checks before repairing the steering system:

1. Verify the customer concern by operating the steering system.
2. Inspect Tires
1 Check the tire pressure. For additional information, refer to the Vehicle Certification (VC) label.
2 Verify that all tires are sized to specification.
3 Check the tires for damage or uneven wear.
3. Belt and Tensioner Check
1 For diagnosis and testing of the accessory drive system, refer to Engine.
4. Fluid Level Check
1 Verify that the power steering fluid level is within the appropriate hot or cold range on the dipstick. Add MERCON (R) automatic transaxle fluid (ATF).
5. Air Bleeding
1 Verify that there is no air in the power steering system. Run the engine until it reaches normal operating temperature. Turn the steering wheel to the left and right several times without hitting the stops.
