Pinpoint Test E : DTCS P0745:12, P0745:13, P0745:19: Notes
WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
Refer to Wiring Diagram Four Wheel Drive Systems for schematic and connector information.
Normal Operation and Fault Conditions
The eLSD system HCU pressure is control by pressure control valve which receives signal from DCMR as part of the normal system operation. Loss of this signal data causes the system to set a DTC.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| P0745:12 | Pressure Control Solenoid A: Circuit Short To Battery | This DTC occurs when DCMR detects a short to voltage signal. |
| P0745:13 | Pressure Control Solenoid A: Circuit Open | This DTC occurs when DCMR detects a open circuit signal. |
| P0745:19 | Pressure Control Solenoid A: Circuit Current Above Threshold | This DTC occurs when DCMR detects a high current signal. |
