DTC C102D-07: High Friction Inside Power Steering - Mechanical failures: Action

NOTE:

Do not damage bellows on steering gear removal. Failure to follow this instruction may result in warranty becoming invalid for steering gear assembly

Disconnect the steering gear from the suspension. Check the suspension system for freedom of movement or abnormally high friction
Remove the steering gear boots and check for evidence of water inside the steering gear boots. If evidence of water ingress is present, replace the steering gear. Refer to the new module/component installation note at the top of the DTC index
Check the steering gear for abnormally high friction. If abnormally high friction is found, check if the onset of the steering system fault symptoms occurred at the same time that the DTC was logged. If the customer reports of heavy steering coincide with the logging of this DTC, then install new steering gear as required
If the DTC was logged between medium and high time (medium to high mileage) in service it is most likely caused by impact or water ingress damage. Please refer to - Electric Power Steering Gear Damage Assessment Checklist - in section 211 - 02 Diagnosis and Testing of the service information
