CAN simulator module for 2007-2013 General Motors SUV Suspension Warning Light repair

For Service Suspension System error removal module Escalade 3, Avalanche, Suburban, Tahoe, Yukon (2007-2014)

If you decide to change the standard shock absorbers with the Magnetic Ride Control system to the usual “passive” ones, the question will surely arise how to clear the "Service Suspension System" error message on the dashboard.This problem can be solved in several ways, reprogram the car system to work with passive suspension, the solution is probably the most optimal, but this can do only GM dealer and price is high. The second way, just to deceive the Suspension ECU by connecting a load resistor of the desired characteristics. Immediately you need to warn that the resistors are very hot, there were cases that the plastic elements with which they were in contact melted because of them, it’s not difficult to come across the possible consequences. The resistor should only be installed in a cooling aluminum casing and attached to metal elements.

The third method is use CAN bus emulator GMEMU3. GMEMU3 will send messages to other car electronic, that suspention works fine.
