Pinpoint Test P : U0300:00: Notes
Refer to Vehicle Dynamic Systems for schematic and connector information.
Normal Operation and Fault Conditions
The ABS module requires the current vehicle configuration information to operate correctly. This information is programmed into the ABS module when a new module is installed. The BCM sends the vehicle configuration information to the ABS module over the HS-CAN, the ABS module compares this information with the programmed information.
The SASM requires the current vehicle configuration information to operate correctly. Vehicle configuration information is sent to the SASM from the BCM over the HS-CAN each time the ignition is set to ON. The SASM stores this information for later use. When the ignition is set to ON following the installation of a new BCM, the vehicle configuration information stored in the SASM does not match the configuration information sent by the newly installed BCM. Once the BCM has been programmed with the vehicle configuration information, the SASM Diagnostic Trouble Codes (DTCs) must be cleared and the ignition must be cycled from ON to OFF and back to ON again.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| U0300:00 | Internal Control Module Software Incompatibility: No Sub Type Information | This DTC sets when the vehicle configuration information transmitted by the BCM does not match what is stored in the ABS module or the SASM. Incomplete or improper flash programming procedures, a loss of communication between the BCM and the ABS module or the SASM, swapping modules between vehicles or an internal failure of one or more modules causes a mismatch of vehicle configuration information between the modules. |
