Some early-model Tesla vehicles (Roadster & S) come equipped with Baolong TPMS sensors. However if a customer visits a Tesla service center with TPMS issues, it's possible that the car has been converted to Continental. The retro-fit process typically involves...
Welcome
TPMS Diagnostics
If the TPMS warning light is on, then technicians should test each sensor using a tool; any sensors that don’t respond after trying several times or show low battery or inaccurate pressure/temperature should be replaced. A solid warning light indicates low pressure; a...
Ford TPMS Relearn w/o Tool
Drive the vehicle for over 2 minutes above 20 mph Park vehicle and turn the ignition off Turn the ignition on Turn the hazard flashers on and then off 3 times. The horn will beep and TPMS warning light should start blinking Note: the on/off cycle must be completed...
Suzuki TPMS Relearn
Even though Suzuki is a Japanese manufacturer, its vehicles learn TPMS sensors differently than other Asian makes (Honda, Toyota, etc). Typical method for initializing learn mode is by pushing the door-open switch in a certain sequence. The switch can be found on the...
TPMS Relearn Procedures
When installing new TPMS sensors, a relearn should be performed unless the original sensors were cloned. The learning process should also be done when rotating tires. Most vehicle manufacturers use the same procedure across all their models, but there are some...
TPMS Qualifiers
Most vehicles use only one TPMS protocol across all trims. However, some cars & trucks use different sensors. Many qualifiers are easily checked - submodel, engine, production date, build location, coupe vs convertible, transmission type, key style, dually vs...
Cloning OE Sensors
When programming Alligator TPMS sensors, techs have the option of cloning the original sensors. If the OEM part is cloned, then a relearn isn't necessary.To clone using the Alligator TPMS tool, select Copy ID in the Program Sensor menu. If the OEM part's battery is...
TPMS Valve Styles
Early TPMS sensors came with non-replaceable metal valves. Whenever a tire is serviced, a new service kit should be installed onto the valve to replace worn-out components (nut, grommet, cap & core). Later sensors came equipped with replaceable rubber valves. The...
Locked OBD Ports on Chrysler & Mercedes
Some newer Chrysler & Mercedes vehicles (model 2019-) come with increased security for their on-board diagnostic system (OBD) to prevent hacking. As a result, some scan tools aren't able to communicate with the cars' system for TPMS sensor-ID registration...
TPMS Technology
TPMS is a technology that's constantly changing. The sensor hardware and part behavior of early systems was quite different than what's used today. Some of the first vehicles with TPMS had sensors that were activated magnetically. Others had parts with no sleep mode,...
