Scan Tool Data Definitions: Notes

The electro-hydraulic power steering (EHPS) scan tool data display values and definition information that can assist in diagnosing EHPS related problems, especially when no diagnostic trouble codes (DTC) are stored in memory. A vehicle's scan tool data can be compared with the data display values from a known good vehicle in the scan tool data display table. When data from the vehicle differs from the typical data display value, the data definition information will help in understanding the nature of the difference and the source of the problem. This list is in alphanumeric order.
