P0982: Shift Solenoid D Control Circuit Low

Definition

The OBD2 code P0982 indicates that there is a low voltage or an issue in the control circuit for Shift Solenoid D, which affects the transmission's ability to shift properly

Common causes

Faulty shift solenoid D
Wiring issues (shorts or open circuits)
Poor electrical connections
Faulty transmission control module (TCM)
Low transmission fluid level
Contaminated transmission fluid
Internal transmission failure

Common misdiagnoses

Transmission fluid issues
Faulty transmission control module (TCM)
Wiring or connector problems
Shift solenoid failure
Transmission valve body issues
Engine control module (ECM) problems
Incorrectly diagnosed transmission failure
Other shift solenoid circuit issues

Troubleshooting steps

1.Check for Additional Codes
Use an OBD-II scanner to check for any other trouble codes that may be present. This can provide more context and help identify if there are related issues
2.Inspect Wiring and Connectors
3.Visually inspect the wiring and connectors associated with the shift solenoid D. Look for signs of damage, corrosion, or loose connections
4.Pay special attention to the wiring harness for any fraying or breaks
5.Test the Shift Solenoid
6.If accessible, test the shift solenoid D for proper operation. You can do this by measuring the resistance across the solenoid terminals with a multimeter. Compare the readings to the manufacturer's specifications
7.If the solenoid is faulty, it may need to be replaced
8.Check the Transmission Fluid
9.Ensure that the transmission fluid is at the correct level and in good condition. Low or dirty fluid can affect solenoid operation
10.If the fluid is contaminated, consider performing a transmission fluid change
11.Inspect the Transmission Control Module (TCM)
12.Check for any issues with the TCM, as it controls the operation of the shift solenoids. Look for signs of damage or corrosion
13.If possible, reprogram or reset the TCM to see if that resolves the issue
14.Test the Circuit
15.Use a multimeter to test the voltage and ground at the shift solenoid connector. Ensure that the solenoid is receiving the correct voltage as specified by the manufacturer
16.If the voltage is low, trace the circuit back to find any breaks or shorts
17.Check for Ground Issues
18.Ensure that the ground connections for the solenoid and TCM are secure and free of corrosion. A poor ground can lead to low voltage readings
19.Perform a Visual Inspection of the Transmission
20.Look for any signs of leaks or damage to the transmission that could affect solenoid operation
21.Clear the Codes and Test Drive
22.After performing any repairs or adjustments, clear the trouble codes and take the vehicle for a test drive to see if the code returns
23.Consult a Professional
24.If the issue persists after performing these steps, it may be necessary to consult a professional mechanic or technician who has experience with transmission issues and OBD-II diagnostics. By following these steps, you should be able to identify and resolve the issue related to the P0982 code
