TPMS Diagnostic Information – Cadillac CTS, 2004-2020
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 Cadillac CTS 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 Cadillac CTS, an OBD TPMS relearn is recommended to write the IDs to the vehicle’s ECU.
The video above shows a GMC Acadia, but the same procedure will work on a Cadillac CTS.
Manual (stationary) relearn procedure, years 2004-2020:
TIP: Lowering driver’s side window may help to complete this process on larger vehicles.
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:
Use the VT56 or VT46 branded tools to change placard pressure for the Cadillac CTS (available for years 2008-2011 & 2014-2020) 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.
Use the VT56 to retrieve Cadillac 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 Cadillac DTC TPMS information to diagnose and service the TPMS issues determined. Available for the Cadillac CTS for years 2008-2011 & 2014-2020 only.
