This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with the car's computer that controls the transmission. It's like when a light bulb in your house has a short circuit and won't turn on properly.
The Transmission Control Module (TCM) is responsible for controlling the transmission's operations. A short circuit in the LED output means that the TCM is not able to communicate properly with the LED indicator, which can affect how the transmission behaves.
P1706 is a diagnostic trouble code (DTC) indicating that the Transmission Control Module has detected a short circuit in the LED output circuit. This can prevent the TCM from correctly signaling transmission status, potentially affecting vehicle performance.
• Transmission warning light on the dashboard
• Erratic transmission behavior
• Inability to shift gears properly
• Damaged wiring or connectors in the TCM circuit
• Faulty Transmission Control Module
• Short circuit in the LED output circuit
Transmission Control Module (TCM): A computer that controls the transmission's functions.
Short Circuit: An electrical circuit that allows a current to travel along an unintended path.
• Inspect the wiring and connectors related to the TCM for damage.
• Check for any visible signs of a short circuit in the LED output circuit.
• Test the TCM for proper functionality.
• Repair or replace damaged wiring or connectors.
• Replace the faulty Transmission Control Module if necessary.
• Ensure the LED output circuit is free of short circuits.
• Multimeter
• OBD-II scanner
• Wiring diagram

Moderate
• Nissan Altima
• Ford Explorer
• Chevrolet Silverado
• Regularly inspect wiring for wear and tear.
• Avoid exposure of electrical components to moisture.
• Perform routine maintenance checks on the transmission system.
Electrical Issue
• Do not ignore the transmission warning light.
• Seek professional diagnosis if unsure.
• Regularly maintain the vehicle's electrical systems.
Check with your vehicle manufacturer for warranty coverage on transmission components.
P1706 has been associated with issues in vehicles with complex transmission systems, particularly in models with advanced electronic control modules.
Moderate – This issue should be addressed promptly to avoid further transmission problems.
Driving with a malfunctioning transmission can be unsafe. Ensure repairs are conducted by a qualified professional.
• Vehicle should be in a safe and secure location.
• Ensure the engine is off before inspecting electrical components.
The Transmission Control Module is typically located near the transmission or under the dashboard.
Q: What does a short circuit mean?
A: A short circuit occurs when electricity takes an unintended path, which can cause malfunctions or damage.
Q: Can I drive with a P1706 code?
A: It's not recommended to drive with this code active, as it can lead to transmission issues.
