U0418 - INVALID DATA RECEIVED FROM BRAKE SYSTEM CONTROL MODULE
| Description: | The powertrain control module (PCM) continuously monitors controller area network (CAN) for messages from the anti-lock brake system (ABS) module. This DTC sets when the PCM does not receive the ABS message within a defined time period, or when the message received is out of expected range, or if the message received contains invalid data. When this DTC is set the regenerative braking is disabled until the next driving cycle. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | Network DTC concerns occur during module-to-module communication. Check for ABS module DTCs. If no ABS module DTCs are present, carry out the network test on the scan tool. If the network test fails, refer to the MODULE COMMUNICATIONS NETWORK -- FUSION, MILAN & MKZ , and carry out the diagnosis for the module that fails the network test. If the network test passes, clear the DTCs, the concern is not present at this time. | ||
