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 Dodge Grand Caravan 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 for one or more wheels of a Dodge Grand Caravan, a TPMS relearn is recommended to transfer the new TPMS sensor IDs to the vehicle’s ECU.

Type of TPMS system:

• Direct TPMS, TPMS sensors are installed in the wheel, tire pressure is communicated via radio frequency (RF) technology from the sensor to the vehicle’s ECU

OE and Aftermarket (Universal, Hybrid, Programmable, Configurable, One-to-One, OE-style) options for TPMS sensor replacement:

• All OE, programmable, configurable, hybrid and OE-type (one-to-one) TPMS sensor options and service kits can be found in the VT56 TPMS Tools and most Powered by ATEQ tools.

Type of TPMS frequency:

• 315 MHz, years 2004-2007
• 433 MHz, years 2001-2003 & 2008-2020

Type of Relearn procedures:

• Auto relearn procedure
• Bonus OBD relearn procedure coverage as an option on the VT56 and VT46 branded tools for years 2001-2020, requires OBD module

Type of TPMS tool required for TPMS reset:

• TPMS activation tool such as VT15, VT31, VT36 or VT56 for auto relearn
• VT56 TPMS SCAN TOOL with OBDII module includes Sync ID technology 

Auto relearn procedure:

• OBDII dongle is not required 
• Confirm TPMS sensors are properly installed 
• Adjust tire pressures to placard value 
• Active sensors with TPMS tool 
• Drive for up to 20 minutes about 15 MPH or until TPMS light is off 

Bonus coverage, OBD relearn procedure

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

Troubleshooting tips

Oversized Rims

If you notice interference of your TPMS signal, it could be due to oversized rims which can cause RF signal interference.

Sensor frequencies

The Dodge Grand Caravan was manufactured with 433 MHz TPMS sensors from 2001 through 2003. Models between the years 2004 and 2007 are manufactured with 315 MHz TPMS sensors. However, starting in 2008 through 2020, models went 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. 

Auto-relearn, the light won’t turn off?

The auto relearn procedure steps require the technician to drive for at least 5 minutes at 28 mph. Unfortunately, when you’re at the shop, it is not always easy or time-valuable to drive a vehicle around at over 28 mph for that amount of time. If the shop is in a city, it may not be possible to drive for over 28 mph unless the user drives outside of a city environment where it is possible to drive at higher speeds.

Solution? For Dodge Grand Caravan vehicles 2001-2020, the bonus OBD relearn procedure is available for the ATEQ VT56, thanks to patented Sync-ID technology. This advanced feature allows the user to perform an OBD relearn to turn the light off, with minimal to no driving time required to turn the light off, saving the technician time and the customer labor costs.

Placard Pressure Adjustment 

Use the VT56 or VT46 branded tools to change placard pressure for the Dodge Grand Caravan if upsizing tires/wheels, also when replacing with off-road tires or low-profile tires. 

Please note: to determine appropriate placard pressure, always follow the tire load and inflation standards. Maintain the overall circumference to +/-3% of the original size, and the required load rating located on the manufacturing placard. Always refer to the vehicle’s owner’s manual for any specific safety advice regarding the application of replacement tires.

TPMS DTC code information

Use the VT56 to retrieve Dodge 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 Dodge DTC TPMS information to diagnose and service the TPMS issues determined.
