This summary uses the existing diagnostic information shown in full below.
This code means the car tried to switch to reverse gear while it was going too fast, which could be dangerous.
The vehicle's control system detected an attempt to engage reverse gear while the car was moving at a speed higher than allowed for safe operation.
The transmission control module (TCM) monitors the speed of the vehicle and the gear selection. If it detects an attempt to engage reverse gear while the vehicle is moving forward at a speed above a certain threshold, it triggers this code to prevent potential damage to the transmission and ensure safety.
• Check Engine Light is on
• Inability to engage reverse gear
• Unusual transmission behavior
• Driver error attempting to shift to reverse while moving forward
• Faulty gear selector switch
• Transmission control module malfunction
Transmission Control Module (TCM): A computer that controls the transmission's operation.
Gear Selector Switch: A component that detects the driver's gear selection.
• Verify the code with an OBD-II scanner.
• Check the gear selector switch for proper operation.
• Inspect the transmission control module for faults.
• Replace faulty gear selector switch.
• Repair or replace the transmission control module.

Transmission Control Issue
• Do not attempt to engage reverse while driving forward.
• Have the vehicle inspected by a professional if this code appears.
Check with the vehicle manufacturer for warranty coverage on transmission components.
This code has been associated with attempts to improve transmission safety by preventing accidental engagement of reverse gear while moving forward.
High – Immediate attention is required to prevent potential transmission damage.
Driving with this issue can be dangerous and may lead to transmission failure. Immediate repair is advised.
• Vehicle must be in motion.
• Attempt to engage reverse gear.
The gear selector switch is typically located near the transmission or gear shift assembly.
Q: Can I drive my car with this code?
A: It's not recommended, as it could lead to transmission damage.
Q: What happens if I ignore this code?
A: Ignoring this code could result in unsafe driving conditions and potential transmission failure.
