Here are some steps which you should follow in order to diagnose this fault code:

• This is a general type of error code which is diagnosed with the help of a scanner.
• The mechanic will insert a scanner to diagnostic port of the vehicle and recover the codes and freeze frame data.
• If he happens to find any additional error codes, he has to address them as well.
• Once it is done, he has to reset the vehicle, and then test drive to see if the error code appears.
• If the error code does not return, then there can be an erratic condition.
• But, if the error code returns, then the mechanic has to check the transmission fluid.
• If the transmission fluid is dirty or if it is below the expected level, it has to be refilled or the dirty fluid has to be replaced.
• Also, the mechanic can check for any sign of leaks, and quickly fix the issue.
• Then the mechanic has to check the wires, connectors and other electrical components and quickly replace them if he finds them to be damaged or defective.
• If the issues are not yet sorted out, then the mechanic will use a digital voltmeter/ ohmmeter and connect it to the vehicle.
• Once the circuit is inspected, he will thoroughly check all the harness and repair them accordingly.
• In most cases, this error code can arise mostly because of any shorted wires or dirty or contaminated transmission fluid.
• Whenever the mechanic or a trained professional, repairs any of the component like wires or connectors, he will reset the code and test drive the vehicle again to see if the error code appears again.
• This can actually help the mechanic to know if the problem is fixed.
