The Suzuki P0974 Code indicates a malfunction in the shift solenoid control circuit. This code is triggered when the voltage in the shift solenoid valve located in the Transmission Control Module (TCM) is higher than it should be, even though the TCM is commanding the shift solenoid valve to turn off. This issue could be caused by various things, ranging from a shift solenoid valve circuit that is open or shorted to the power circuit, a malfunction of the shift solenoid valve itself, or even an issue with the TCM. Below is a table outlining the causes and solutions for the Suzuki P0974 Code.

When a Suzuki vehicle’s computer detects an issue with the shift solenoid control circuit, it triggers the P0974 Code. This code can indicate various topics, from a shift solenoid valve circuit that is open or shorted to the power circuit, malfunctioning the shift solenoid valve itself, or an issue with the TCM. Understanding the causes and solutions for the Suzuki P0974 Code is important to diagnose the problem.
Shift Solenoid Valve Circuit Open or Shorted to Power Circuit
The shift solenoid valve circuit is responsible for controlling the flow of fluid through the transmission. If the circuit is open or shorted to the power circuit, it can cause the Suzuki P0974 Code to be triggered. The solution to this issue is to repair or replace the faulty wiring or harness.
Malfunction of Shift Solenoid Valve
The shift solenoid valve is responsible for controlling the flow of fluid through the transmission. If it is malfunctioning, it can cause the Suzuki P0974 Code to be triggered. The shift solenoid valve needs to be repaired or replaced to fix this issue.

TCM Issue
The Transmission Control Module (TCM) controls the shift solenoid valve and other components in the transmission. If it is malfunctioning, it can cause the Suzuki P0974 Code to be triggered. The solution to this issue is to repair or replace the TCM.
Faulty Connection
The wiring and connections between the TCM and the shift solenoid valve can become faulty over time. If this happens, it can trigger the Suzuki P0974 Code. To fix this issue, all the wiring and connections must be checked, and any problems found must be repaired.
Conclusion
The Suzuki P0974 Code is an indication of a malfunction in the shift solenoid control circuit. This code can be caused by various things, ranging from a shift solenoid valve circuit that is open or shorted to the power circuit, a malfunction of the shift solenoid valve itself, or even an issue with the TCM. To properly diagnose and fix the problem, it is important to understand the causes and solutions for the Suzuki P0974 Code.
