The automobile fault code P1857 indicates a problem with the Transfer Case Control Module (TCCM). The most common symptom is the Engine Light being ON or the Service Engine Soon Warning Light.
The cause of this fault code can be a faulty TCCM, an open or shorted TCCM harness, a poor electrical connection in the TCCM circuit, or a faulty transfer case or front axle assembly. To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion.
Additionally, look for any broken, bent, pushed out, or corroded pins in the connectors.
The repair time for this issue is estimated to be around 1.0 hour.

P1857 Fault Code: Understanding The Description And Troubleshooting Steps
The P1857 fault code indicates a short circuit to ground in the transfer case contact plate ‘C’.
This contact plate is responsible for communicating the operator’s choice to the Transfer Case Control Module (TCCM).
When the TCCM commands the gearmotor encoder assembly to 4H mode, the transfer case shift fork engages 4H mode and activates the dual-cone synchronizers to synchronize the front and rear drivelines. Additionally, the hublock vacuum solenoid engages the Constant Vacuum Hublock (CVH) at each front wheel. If your vehicle is not responding as intended, it is important to systematically check the necessary inputs and outputs of the TCCM, components of the transfer case, CVH components, and axle shafts. It is recommended to inspect all circuits for any opens or shorts to power or ground.
By identifying and resolving the short circuit issue in the transfer case contact plate ‘C’, you can ensure proper communication between the operator and the TCCM, allowing for smooth engagement of the desired mode.
FAQ
If you’re seeing the engine light on or the service engine soon warning light, the fault code P1857 could be the culprit. This code is often caused by a faulty Transfer Case Control Module (TCCM), an open or shorted TCCM harness, a poor electrical connection in the TCCM circuit, a faulty transfer case, or a faulty front axle assembly. To visually inspect these possible causes, check the wiring harness and connectors for any damage. Look out for broken, bent, pushed out, or corroded pins in the connectors.
If you’re experiencing the dreaded p1857 fault code with the engine light on, it could be due to a faulty Transfer Case Control Module (TCCM). To confirm this, visually inspect the wiring harness and connectors for any damage. Look out for broken, bent, pushed out, or corroded pins on the connectors. By checking these possible causes and addressing any issues with the TCCM, you can fix the problem and get your engine light turned off.
