Technical Definition:

Torque Converter Clutch Circuit Electrical

Technical Description:

The diagnostic trouble code is set when the Engine Management Computer (EMC) also known as the Powertrain Control Module (PCM) and also known as the Engine Control Module (ECM) detects a fault with the torque converter clutch (TCC) solenoid electrical circuit, which is contained inside the transmission.

Possible Causes:

• Low or dirty transmission fluid
• Wire/circuit issue shorted to power or ground
• Failed torque converter clutch (TCC) solenoid
• Failed TCC assembly in the torque converter
• Failed PCM/ECM/EMC

Possible Symptoms:

• Malfunction indicator illumination (check engine light or service engine soon light)
• Stalling when coming to a stop after cruising speeds
• Shudder on take off
• Shudder when coming to a stop

Torque Converter Clutch Circuit Electrical

Possible Solutions:

• On Board Diagnostic (OBD-II) scan tool – to pull the code; can be found at many parts stores, online, or many parts stores will pull the code for free
• Multimeter that has a resistance (or OHM) reading
• Self powered test light/probe (a Power Probe III works wonders here). If you don’t have a Power Probe, a simple set of fused jumper wires and a test light will suffice
• Wire diagrams will be very helpful – you can get these in a Haynes manual or if your friendly with the dealer or your local mechanic, they may be able to run off a photocopy
