TPMS simulator v1.3 for GM vehicles, from IRON GATES
The TPMS simulator replaces one, two, three or four tire pressure sensors that equip General Motors vehicles, models mentioned on the website produced mainly for Europe and North America.
Further down below are the unit’s operating modes. Going from one mode to the other is done sequentially as the arrows depict and it is accomplished by pressing the small black button. Do allow at least 4 seconds between presses of the button:
It is best to set up the simulator in a quiet place, radio-wise. Avoid the mall parking lot or gas stations. If your device is battery powered there is a big on / off red button; use it to turn on the device. If it is cable powered plug it in to a 12V socket.
Note there are 5 different preset pressure values; each time the device is turned on the next pressure preset value is used. The led will indicate which pressure preset value is being used by blinking once – five times upon powering the device on; this is a transitory “visual check of pressure preset value” mode, not depicted above, which immediately ceases and leaves the device in normal mode from the state diagram above. This transitory mode only happens at device power-on and no button presses are necessary to advance into next mode.
The fifth off/on cycle puts the device back to the current pressure value. In the advent you will see a “low tire pressure”, “check tire pressure” or similar message turn the device off and on and reattempt. One, or likely more than one of the values will work with your vehicle. Once a good preset value has been found long press the setup button (2 seconds). That locks the good PSI into the device, so that further power cycling does not change it any longer. There is no led indication to the long press, verify the PSI-blinks is the same by power cycling the device a few times. Long press it again to unlock.
Vehicle dependent steps
Put your vehicle in TPMS relearn mode (not TPMS reset mode, they could be different for your vehicle) according to the appropriate how-to at http://www.tpmsrelearn.com/
Should the site above become unavailable there is a PDF file describing the same procedures on my website – https://spooftpms.com .
After training the last sensor ID (Left Rear, either simulated or real ID) tire the vehicle will exit TPMS relearn mode and display some sort of indication. If the vehicle is not equipped with message center display, successful completion can be verified in other manners – vehicle dependent. The most obvious is to switch ignition off, then turn the engine on and notice the TPMS dashlight, which should not persist.
Troubleshooting and returning the device
When you are alternating between the simulator and real pressure sensors it is recommended to open the simulator device and take out the batteries. Their life will be extended (when there is no on / off button), and this also eliminates the risk of them leaking inside the device.
