Normal Operation

The PSCM uses the motor inside the EPAS gear to calculate the relative and actual steering wheel angle, then transmits this information to other modules over the HS-CAN.

This test generates a RVC for a new PSCM when directed to do so from pinpoint test. A RVC is required to order a new PSCM and to document billing for payment.

1. E1: TEST DRIVE TO CHECK FOR RETURNING DTCS 
   NOTE: Always drive the vehicle in a safe manner according to driving conditions and obey all traffic laws.
   • Clear the PSCM DTCs.
   • Cycle the ignition to OFF and then back to RUN.
   • Test drive the vehicle in the following manner:
     • With the engine running/ready, stop the vehicle on an unsealed concrete or asphalt surface (in order to provide adequate friction for a thorough test).
     • With the vehicle in gear and the brakes applied, turn the steering wheel lock-to-lock.
     • Return the steering wheel to the center position and move the vehicle forward approximately 32 cm (1 ft).
     • With the vehicle in gear and the brakes applied, turn the steering wheel lock-to-lock.
     • Return the steering wheel to the center position and move the vehicle forward approximately 32 cm (1 ft).
     • With the vehicle in gear and the brakes applied, turn the steering wheel lock-to-lock.
     • The test drive is complete.
   • Retrieve the continuous memory DTCs.
   • Is DTC C1B00:2F present? 

     Yes

     No

     Go to  E2.

     The condition to set the DTC is not present at this time. DISCONNECT and INSPECT all 3 PSCM connectors for corrosion, bent terminals and/or pushed-out pins. REPAIR as necessary. If the connectors are okay, INSPECT the wire harness along the top of the EPAS gear for cuts, breaks and/or pinches. REPAIR as necessary. For all other PSCM DTCs, REFER to the PSCM DTC Index. If this is a Ford paid repair, INCLUDE the RVC on the warranty claim form.

2. E2: INSPECT THE INNER TIE RODS 

• With the transmission in NEUTRAL, position the vehicle on a hoist. Refer to Jacking And Lifting .
  NOTE: When installing new bellows boots and clamps apply new lubricant as instructed to prevent water contamination or damage may result to the EPAS gear. For complete information refer to the Tie Rod - Inner Removal and Installation procedure in Electronic Power Assist Steering (EPAS) System .
• Inspect the inner tie rods for correct installation. Refer to Electronic Power Assist Steering (EPAS) System .
• Are the inner tie rods correctly installed? 

  Yes	No
  INSTALL a new EPAS gear. REFER to Electronic Power Assist Steering (EPAS) System . ORDER a replacement PSCM and INCLUDE the RVC on the form. If this is a Ford paid repair, INCLUDE the RVC on the warranty claim form. When complete, SELECT the "X" in the top right corner to CLOSE this procedure.	INSTALL a new Inner tie rod(s).
