The P1829 fault code refers to a problem with the transmission transfer case counter clockwise shift relay coil.

This coil is responsible for activating the transfer case clutch within the transfer case. Inside the transfer case, there is an electromagnetic clutch that spins up the front driveline when shifting from 2WD to 4H mode at speed. When the control switch is turned, the Generic Electronic Module (GEM) recognizes the shift request and activates the electromagnetic clutch and relays that power the transfer case shift motor.

The shift motor moves to the desired position, as determined by the contact plate position inputs to the GEM, and then power to the shift relays and motors is removed. The transfer case front and rear output shafts are synchronized, and a spring-loaded lockup collar engages the mainshaft hub to the drive sprocket.

Finally, the front axle collar is engaged and the electromagnetic clutch is deactivated. However, if the P1829 fault code is present, it means that there is an open circuit in the transmission transfer case counter clockwise shift relay coil.

This can prevent the transfer case clutch from being activated properly, leading to issues with shifting between 2WD and 4H modes.

What are the possible causes of the automobile fault code P1829?

If you see the engine light or service engine soon warning light on, the fault code P1829 could be the culprit. This code is often caused by a faulty Generic Electronic Module (GEM), an open or shorted GEM harness, or a poor electrical connection in the GEM circuit. To fix this issue, visually inspect the wiring harness and connectors, checking for any damage or corrosion. Additionally, look out for broken, bent, pushed out, or corroded connector pins.
