IV1: Visual Inspection
Verify the customer concern.
Visually inspect the EPAS system for obvious signs of mechanical or electrical damage.
NOTE:
When inspecting the bellows boots make sure to use a strong light source and an inspection mirror.
NOTE:
The ignition must be off, and remain off, when disconnecting PSCM electrical connectors. Failure to follow this direction may lead to DTCs being set in the PSCM that cannot be cleared, and result in the need to install a new EPAS steering gear.
