[SOLVED] P1828 Code: Fixing Transmission Transfer Case Shift Relay Circuit Failure

The automobile fault code P1828 indicates a problem with the Generic Electronic Module (GEM).

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 GEM, an open or shorted GEM harness, or a poor electrical connection in the GEM circuit.

To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion.

Look out for broken, bent, pushed out, or corroded pins in the connectors. The repair time for this issue is estimated to be around 1.0 hour.

To interpret the fault code, refer to the “Possible Causes” listed above and follow the recommended steps for inspection and repair.

The factors influencing the cost of diagnosing and fixing the automobile fault code P1828 based on the estimated repair time of 1.0 hour include the hourly rate charged by auto repair shops, which typically ranges between $75 and $150.

The P1828 fault code refers to a failure in the transmission transfer case counter clockwise shift relay coil circuit.

The transfer case in an automobile is equipped with an electromagnetic clutch that is responsible for spinning 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.

Once the shift motor reaches the desired position, power to the shift relays and motors is removed.

The transfer case front and rear output shafts are then synchronized, and the 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.

The transfer case clutch relay, which is an electromechanical relay, is used to activate the transfer case clutch within the transfer case.

The P1828 fault code indicates a failure in the transmission transfer case counter clockwise shift relay coil circuit, which may result in issues with shifting between 2WD and 4H modes.

What are the possible causes of the automobile fault code P1828?

If you see the engine light or service engine soon warning light on, the fault code P1828 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.

How can I visually inspect the wiring harness and connectors to fix the P1828 fault code?

If you’re dealing with the P1828 fault code and your engine light is on, it’s time to take a closer look at the wiring harness and connectors. The culprit could be a faulty Generic Electronic Module (GEM) or an open or shorted GEM harness. To fix the issue, visually inspect the wiring harness and connectors for any signs of damage. Keep an eye out for broken, bent, pushed out, or corroded pins on the connectors. Don’t forget to check the “Possible Causes” mentioned earlier.

What should I look for when checking for damaged components and connector pins to resolve the P1828 fault code?
