They are used for reading codes and performing diagnostics and programming functions tailored to the vehicles. OEM-specific OBD2 scanners are typically more expensive than generic OBD2 scanners and are essential for complex tasks, such as programming keys and configuring new control units.

Specification and maintenance of OBD2 scanners that read transmission codes

Transmission codes are set by the vehicle’s transmission control module (TCM) when it detects a problem in the transmission system. The TCM monitors various components of the transmission system, such as the transmission fluid level, temperature, and input and output speed sensors.

• Input Speed Sensor: This sensor measures the speed at which the vehicle’s wheels are turning and sends this information to the TCM. If there is a problem with this sensor, it can cause issues with gear shifting and timing.
• Output Speed Sensor: Similar to the input sensor, the output speed sensor measures the speed of the transmission fluid as it leaves the transmission. This information helps the TCM determine how hard to shift gears.
• Transmission Fluid Level Sensor: This sensor monitors the level of transmission fluid in the vehicle. If the fluid level is low, it can cause problems with gear shifting and can damage the transmission over time.
• Transmission Temperature Sensor: This sensor measures the temperature of the transmission fluid. If the transmission fluid is too hot or too cold, it can affect the performance of the transmission.

When any of these components have problems, they send signals to the TCM, which then sets a transmission code. The code indicates to the mechanic or technician what the TCM has detected as a problem.

Some common transmission codes include P0700, which indicates a generic transmission control system fault, and P0720, which indicates an output speed sensor circuit problem. OBD2 scanners that read transmission codes can help identify these codes and provide insights into the possible causes of the issues.
