Action Taken When the DTC Sets Conditions for Clearing the MIL/DTC Diagnostic Aids Test Description The numbers below refer to the step numbers on the diagnostic table. 2. This step verifies that the PCM is receiving a signal from the vehicle speed sensor. 3. This step verifies that there are no opens in the circuitry from the vehicle speed sensor to the PCM connector. 7. This step performs a resistance test on the VSS circuits from the PCM connector. • The transmission defaults to 3rd gear. • The PCM inhibits TCC operation. • The PCM illuminates the Malfunction Indicator Lamp (MIL). • The PCM turns OFF the MIL after three consecutive ignition cycles without a failure reported. • A scan tool can clear the DTC from the PCM history. The PCM clears the DTC from the PCM history if the vehicle completes 40 warm-up cycles without a failure reported. • The PCM cancels the DTC default actions when the fault no longer exists and the ignition is OFF long enough in order to power down the PCM. • Check for PRNDL DTC P0705. DTC P0705 affects transmission operation. This may set DTC P0502 falsely. • Check for Electromagnetic Interference (EMI) in circuits 400 and 401. EMI may be induced if the harness is routed along the spark plug wires. • Inspect the wiring for poor electrical connections at the PCM. Inspect the wiring at the TCC brake switch. Look for the following conditions: – A bent terminal – A backed out terminal – A damaged terminal – Poor terminal tension – A chafed wire – A broken wire inside the insulation • When diagnosing for an intermittent short or open condition, massage the wiring harness while watching the test equipment for a change. • Ensure that the VSS is securely tightened to the case extension.

FORD: 2004-2007 F-Super Duty ISSUE SERVICE PROCEDURE Some 2004-2007 F-Super Duty vehicles, equipped with a power sliding rear window (back glass), may 1. Prior to window removal, verify that center exhibit a stuck or binding concern. This condition glass is centered in the upper plastic channel may be due to the center glass not being positioned (Figure 1). If center glass is not inside upper correctly inside the upper or lower channel, the plastic channel, pull channel down and out of channel being warped, bent, or center glass upper aluminum channel and slide back in de-bonded. making sure the entire center glass is inside the plastic channel. ACTION Follow the Service Procedure steps to correct the condition. Figure 1 – Article 06-15-5 2. If Step 1 resolves the issue, return the vehicle 4. Refer to window removal procedure. (Refer to back to customer after verifying the window Workshop Manual (WSM), Section 501-11-24 functions properly. If it did not resolve the and 501-11-25.) issue, proceed to Step 3. 5. Remove cable clips from sheet metal. (Refer to 3. Open the rear window approximately half way. WSM, Section 501-11-28.) 6. Remove three (3) motor bracket attaching bolts. (Refer to WSM, Section 501-11-28. 7. Disconnect motor wiring harness from vehicle 9. Pull outer rubber seal from window frame body harness. (Refer to WSM, Section (Figure 2). 501-11-29.) 8.

Correction Important: For ease of reassembly, shift the transfer case assembly to 2HI for the NV263 (NP1), or Neutral for the NV246 (NP8) prior to removing any components. For information on placing the NV246 (NP8) transfer case in NEUTRAL, see the procedure at the end of this bulletin. 1. Remove the transfer case and front axle/engine skid plates (if equipped). 2. Disconnect and position the front propeller shaft aside. 3. Disconnect the transfer case encoder motor wiring harness. 4. Remove the three (3) bolts that retain the encoder motor to the transfer case. 5. Separate the encoder motor assembly from the transfer case and place it on a work bench. Important: DO NOT REMOVE THE SCREWS INDICATED WITH THE (1) IN THE ABOVE ILLUSTRATION. 6. Remove the four screws on the outer perimeter of the encoder motor housing. Important: For proper timing and ease of reassembly, hold the gear in place as your remove the cover from the encoder motor assembly with your thumb or finger. 7. Carefully remove the cover from the encoder motor assembly. The cover has a seal on the bottom side. Place the cover in a position to protect this seal from damage and/or contamination. Important: Observe the location of the punch mark on the large gear in relation to the timing mark on the housing if the transfer case was placed in the 2HI for the NV263 (NP1), or Neutral for the NV246 (NP8). The timing marks should be within one tooth of proper alignment. If not, you must note the timing mark positions for reassembly. 8. Locate the two shims; one on the small gear and another on the larger gear. Set them aside on a clean surface for reuse. Important: After removing the large gear from the housing, a dark gray phenolic spacer should remain in the casting where the bottom of the large gear resides. Locate this spacer and save for reuse. 9. Carefully lift the large gear from the housing. The sensor and wiring harness will come with the gear. 10. Disconnect the wiring from the sensor. 11. Separate the sensor from the large gear.
