ISSUE:
Some 2017 Continental vehicles equipped with a 2.7L or 3.0L engine with AWD and built on or before 30-Sep-2016 may exhibit an illuminated malfunction indicator lamp (MIL), low oil pressure warning, inoperative air conditioning (A/C) and/or AWD fault message in the instrument panel cluster (IPC), with fuse F3 open in the battery junction box (BJB). In addition, diagnostic trouble codes (DTCs) P0034, P0245, P0480, P0481, P0645, P06A0, P06DB, P0A15, P0AB7, P2602, P2681, U0284 and/or other communication DTCs may be present.
ACTION:
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
- Connect the Ford Integrated Diagnostic System (IDS) or equivalent scan tool and retrieve DTCs. Are any of the following DTCs present: P0034, P0245, P0480, P0481, P0645, P06A0, P06DB, P0A15, P0AB7, P2602, P2681, U0284 and/or other communication DTCs?
- Yes – proceed to Step 2.
- No – this article does not apply. Refer to Powertrain Control Emissions Diagnosis (PC/ED) manual for normal diagnostics.
- Inspect fuse F3 in the BJB. Is fuse F3 open?
- Yes – proceed to Step 3.
- No – this article does not apply. Refer to PC/ED manual for normal diagnostics.
- Raise the vehicle and remove the underbody shield if equipped. Refer to Workshop Manual (WSM), Section 303-01.
- Visually inspect the engine wiring harness to the power transfer unit (PTU) cooling pump, near connector C1586, for contact and wire chaffing with the electronic power assist steering (EPAS) PTU heat shield. Was a wiring issue found? (Figure 1)
Figure 1- Yes – proceed to Step 5.
- No – this article does not apply. Refer to PC/ED manual for normal diagnostics.
- Disconnect the PTU temperature sensor.
- Disconnect the harness push pin retainer on the EPAS heat shield and the two push pin retainers on the PTU.
- Disconnect the PTU coolant pump electrical connector and the PTU coolant pump harness retainers.
- Position the wiring harness towards the rear of the vehicle to access the damaged wires.
- Repair the wire concern. Refer to cell 5 in the Wiring Diagram (WD). The wiring harness should also be wrapped with Rotunda Technician Tool Program (RTTP) Coroplast wiring harness tape or equivalent.
- Add a new wiring harness retention clip to the harness 20 mm (13/16″) closer to the PTU from the original clip. This will move the harness away from the PTU to prevent chafing on the PTU housing. Remove and discard the original retention clip. (Figure 2)
Figure 2
- Reconnect the PTU temperature sensor, PTU coolant pump and all retainers.
- Attach the new wiring harness retention clip to the lower boss retention point on the PTU. (Figure 3)
Figure 3
- Attach the new wiring harness retention clip to the lower boss retention point on the PTU. (Figure 3)
- Reinstall the underbody shield. Refer to WSM, Section 501-02.
- Replace fuse F3 as required.
