Test 3 - EVO Subsystem Test

1. Disconnect high pressure line at the power steering pump and install power steering system tester SST SA 9134C (or equivalent).
2. Install PDT to the data link connector (DLC) diagnostic port.
3. Open the gate valve on the power steering system tester.
4. Run engine until it has reached normal operating temperature. Replace any power steering fluid lost during power steering tester installation. Bleed system if necessary. (Refer to "Power Steering System Bleed").
5. Using the PDT, select EVO subsystem in the special test menu.
6. With the PDT, command the EVO actuator to provide full assist. Record the power steering fluid flow rate as indicated on the power steering system tester. The flow rate should be between 8.88 and 10.77 LPM (2.35 and 2.85 GPM). If not within this range, replace the EVO actuator.
7. With the PDT, command the EVO actuator to provide no assist. Record the power steering fluid flow rate, as indicated on the power steering system tester. The flow rate should be between 1.51 and 3.40 LPM (0.40 and 0.90 GPM). If not within this range, replace the EVO actuator.
