The Tire Pressure Monitoring System on a C5 Corvette consists of four sensors which keep track of air pressures within each wheel. While being a convenient feature, this system can easily get confused when changing and swapping the wheels on the vehicle. When the system becomes confused, a quick reset must be performed to re-sync each sensor back to the vehicle. In this article we will introduce you to the parts behind the C5 Tire Pressure Monitoring System (TPMS) and help you better understand the programming/reset process. If at any time you get stuck or need help, visit the Request Support section and a Corvette Salvage representative will provide assistance.
Unmasked: Parts Behind the C5 Tire Pressure Monitoring System
The Tire Pressure Monitoring System (TPMS) consists of the following parts:
- Low Tire Pressure Sensors – Each C5 Corvette is equipped with four sensors which are used to track air pressures within each wheel. Each sensor has a unique identification code.
- Remote Function Actuation (RFA) Module – This module stores the transmitted identification codes received from the sensors during the programming process. It also collects the tire pressure values after the sensors have been programmed.
- Tire Pressure Monitoring System (TPMS) Programming Tool – This tool is essentially a strong magnet which allows each sensor to transmit identification codes to the RFA module.
- Instrument Panel Cluster (IPC) – The IPC is used to display prompts during the programming process.
This part is a new C5 Tire Pressure Monitoring System Programming Magnet which can be used on a 1997 to 2004 Corvette.
Computers & Modules
This part is a good, used C5 Remote Function Actuation (RFA) Module which can be installed on a 1997 to 2004 Corvette.
Pre-Warning & Considerations
If the programming process is cancelled before a new sensor is programmed, or if the vehicle’s battery is disconnected, the RFA module/receiver will retain the vehicle’s current sensor identification codes. As soon as the RFA module learns the first new sensor’s identification code, all previously stored codes are erased from the receiver’s memory.
NOTE: The programming process will be cancelled if any of the following conditions are met:
- The programming mode is exited through the Driver Information Center (DIC).
- The ignition is turned OFF.
- All four sensors have been successfully programmed.
- The Tire Pressure Monitoring System (TPMS) has been in program mode for longer than 2 minutes and no sensors have been learned.
If the programming process is cancelled with less than four identification codes stored, the RFA module will only accept the codes programmed up to that point.
For the programming process to work properly, each sensor must transmit a unique code in a specific sequence. A strong magnet is used during the process to help transmit the identification codes to the RFA module. When a sensor has successfully transmitted an identification code, the horn will beep once. The IPC will display prompts as each sensor is programmed and signal when to proceed to the next sensor.
NOTE: Make sure the vehicle has been stationary for at least 2 minutes before attempting the programming process.
- Turn the ignition switch to the ON position. (Engine should be off.)
- Press the RESET button on the Driver Information Center (DIC) to clear any Instrument Panel Cluster (IPC) warning messages.
- Press and release the OPTIONS button on the DIC to cycle through the display options until the IPC display becomes blank.
- Press and hold the RESET button until the “FOB TRAINING” message appears.
- Press the OPTIONS button once and a “TIRE TRAINING” message will appear.
- Press the RESET button once and a “LEARN L FRONT TIRE” message will appear. This message signals the beginning of the programming sequence.
- Hold the Tire Pressure Monitoring System (TPMS) Programming Tool over the valve stem of the left front wheel. When the horn beeps once, programming is complete for the left front wheel ONLY. NOTE: You may have to move the tool around the valve stem to hit the right spot.
- After the horn beep, proceed to program the remaining three sensors. You MUST program the sensors in the order directed by the IPC messages.
- The order of programming is fairly simple to follow. First, start with the (1) LEFT FRONT WHEEL. Wait for the horn beep. Then, move to the (2) RIGHT FRONT WHEEL. Wait for the horn beep. After, move to the (3) RIGHT REAR WHEEL. Wait for the horn beep. Finally, move to the (4) LEFT REAR WHEEL. Wait for the horn beep.
- The programming/reset process has successfully been completed at this point.
