Measure the resistance of the (D51) Dynamics Sensor Low Data Link circuit between the Dynamics
Sensor harness connector and the Anti-Lock Brakes Module harness connector.

Is the resistance below 5.0 ohms?

Yes

Replace the Dynamics Sensor in accordance with the Service Information.

Perform ABS VERIFICATION TEST.

No

Repair the (D51) Dynamics Sensor Low Data Link circuit for an open.

Perform ABS VERIFICATION TEST.

U140E-IMPLAUSIBLE VEHICLE CONFIGURATION DATA RECEIVED

For complete wiring diagrams refer to SYSTEM WIRING DIAGRAMS article.

When Monitored:

Once per ignition cycle, but not during cranking.

Set Condition:

If the Anti-Lock Brakes Module either fails to receive vehicle configuration data from the Engine Control
Module (ECM) or Powertrain Control Module (PCM) or the configuration data it receives from the ECM
or PCM is different than that received during the previous ignition cycle.
