How to reset tire pressure sensor jeep grand cherokee 2012

After the TREAD Act was mandated in 2007, all vehicles manufactured in the United States beginning in 2008, must be installed with direct or indirect TPMS systems.

The Jeep Grand Cherokee uses a direct TPMS system, which means TPMS sensors are installed in the wheel. If one or more tires indicate low tire pressure, the TPMS sensors will transfer the information to the vehicle’s ECU. An indicator light (low-line TPMS system) or each tire pressure will show on the dash (high-line TPMS system).

When a sensor is replaced in one or more tires of a Jeep Grand Cherokee, an OBD TPMS relearn is recommended to write the IDs to the vehicle’s ECU.

Type of TPMS system:

• Direct TPMS, sensors are installed in the wheel
• All OE and aftermarket TPMS part numbers and service kit replacement options for the Dodge Charger can be found in the VT56, VT55, and VT36 TPMS Tools in “Service TPMS”.

Type of TPMS frequency:

• 315 MHz for years 2005-2007
• 433 MHz for years 2001-2004, 2008-2020

Type of Relearn procedures:

• Bonus OBD relearn procedure coverage as an option on the VT56 requires OBD module (for years 2005-2017)
• Auto relearn (for years 2001-2020) 

Type of TPMS tool required for TPMS reset

• TPMS scan tool with OBD module (VT56, VT46 brands)
• TPMS activation tool combined with a Diagnostic Scan Tool (VT15, VT31, VT36, VT46 branded tools)

OBD relearn procedure, years 2005-2017:

• OBDII dongle is required
• Confirm TPMS sensors are properly installed
• Adjust tire pressures to placard value
• Hold TPMS tool on left front tire sidewall next to the valve stem
• Repeat for the right front, right rear and left rear tires
• Apply OBD module to the DLC
• Turn ignition ON
• Press OK on TPMS tool to transfer sensor data to the ECU
• Disconnect OBD module from DLC
• Turn ignition OFF, then ON
• Drive for at least 5 minutes at 28mph

Auto Manual (Stationary) Relearn Procedure, years 2001-2004):

• OBDII connector is not required 
• Magnet is required

• Turn ignition to ON 
• Press and release MENU on overhead console until RE-TRAIN TIRE SENSOR appears 
• Press STEQ and select YES 
• Press MENU until TRAIN LF TIRE appears 
• Hold magnet over left front valve stem 
• Horn chirps 
• Repeat for RF/RR/LR tires 
• Exit relearn menu  

Auto Relearn Procedure, years 2005-2020:

• OBDII connector is not required 
• Confirm TPMS sensors are properly installed 
• Adjust tire pressures to placard value 
• Activate sensors with TPMS Tool 
• Drive vehicle for up to 20 minutes about 15 mph or until TPMS light is off 

Troubleshooting tips

System Fault Issues

If a system fault is detected, the TPM Telltale Light will flash on and off for 75 seconds and then remain on solid. The system’s fault will also sound a chime. If the ignition switch is cycled, this sequence will repeat, providing the system fault still exists. The TPM Telltale Light will turn off when the fault condition no longer exists. A system fault can occur due to any of the following:

1. Signal interference due to electronic devices or driving next to facilities emitting the same radio frequencies as the TPM sensors.
2. Installing aftermarket window tinting that contains materials that may block radio wave signals.
3. Accumulation of snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.

Sensor Frequencies

The Jeep Grand Cherokee was manufactured with 433 MHz TPMS sensors from 2001 through 2004. Then, the vehicle was manufactured with 315 MHz TPMS sensors from 2005 through 2007. In 2008, the Jeep Grand Cherokee switched back to 433 MHz TPMS sensors. Be sure to check the tool in the CHECK TPMS icon on the VT56, VT46, VT36, or VT31 tools to see which sensor frequency you are working with before replacing a TPMS sensor.

TPMS DTC code information

Use the VT56 to retrieve Jeep TPMS DTC codes by selecting the “Service” icon. After selecting the Make, Model, and Year select the DTC code icon. Use the OBDII module to retrieve the Jeep DTC TPMS information to diagnose and service the TPMS issues determined.
