When viewing rear wheel speed sensor information via a Tech 2®, you may notice that the rear wheel speed data is reversed. The Tech 2® will show the left wheel speed data as the right on the Tech 2® screen and the right wheel speed data as the left.
This is the result of the Electronic Brake Traction Control Module (EBCM) sending out the signal to the Tech 2® with the data swapped.
If this condition is present, DO NOT replace the EBCM. To resolve this concern, reprogram the EBCM with updated calibrations. This new service calibration was released with TIS satellite data update version 5.0.
Important: Select EBCM in the TIS2000 supported controller list as the module. As always, make sure that your Tech 2® is updated with the latest software version.
