Normal Operation

The ABS module must be configured with the correct vehicle configuration information for correct operation. The ABS module with the IC over the High Speed Controller Area Network (HS-CAN) must be configured properly, as well as other modules that the ABS module provides information to and receives information from (such as the IC) over the High Speed Controller Area Network (HS-CAN).

The ABS module requires correct vehicle configuration information to operate correctly. This information is programmed into the module when a new module is installed. The IC is also programmed with the vehicle configuration information and shares this information with other modules over the High Speed Controller Area Network (HS-CAN). Incomplete or improper flash programming procedures, a loss of communication between the IC and ABS module, swapping modules between vehicles or an internal failure of one or more modules will cause a mis-match of vehicle configuration information between the modules.

• DTC U2101:00 (Control Module Communication Incompatible: No Sub Type Information) - This DTC sets when the vehicle configuration information transmitted by the IC does not match what is stored in the ABS module.

This pinpoint test is intended to diagnose the following: 

• ABS module
• ABS module configuration
• IC configuration
