Fig. 86: Measuring Resistance Of (D51) Dynamics Sensor Low Data Link Circuit Between 
Dynamics Sensor Harness Connector And Anti-Lock Brakes Module Harness Connector 
Courtesy of CHRYSLER LLC 

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.

1) VERIFY DTC IS ACTIVE 

Turn the ignition on. 

With the scan tool, read and record ABS DTCs. 

With the scan tool, read and record Environmental Data (EV Data). 

With the scan tool, erase ABS DTCs. 

Cycle the ignition switch. 

With the scan tool, read ABS DTCs. 

Does this DTC reset?  

Yes  

Go to 2).  

No  

The condition that caused the symptom is currently not present. Inspect the related wiring for a 
possible intermittent condition. Look for any chafed, pierced, pinched, or partially broken wires.  

Refer to the ABS INTERMITTENT CONDITION.  

2) CHECK FOR ANY OF THE FOLLOWING ACTIVE DTCs 

With the scan tool, read all active DTCs from all CAN C Bus modules. 

Does the scan tool display any active DTCs related to the conditions listed above?  

Yes  

Diagnose and repair the DTC(s). Refer to the DIAGNOSTIC CODE INDEX .  

No  

Go to 3).  

3) CHECK IF TIPM DTCs ARE PRESENT 

With the scan tool, read TIPM DTCs.

NOTE:

Check for CAN C hardware electrical, VIN Missing/Mismatch, battery or 
ignition related DTCs.

Perform BODY VERIFICATION TEST - VER 1 .  

Yes  

Go to 5).  

5) CHECK IF ECM OR PCM DTCs ARE PRESENT 

With the scan tool, read ECM or PCM DTCs. 

Are any DTCs present?  

Yes  

Diagnose and repair the DTC(s). Refer to appropriate Engine ELECTRICAL DIAGNOSTICS 
article .  

Perform POWERTRAIN VERIFICATION TEST .  

No  

Go to 6).  

6) VERIFY CORRECT ECM OR PCM IS INSTALLED IN THE VEHICLE 

With the scan tool, verify that the ECM or PCM part number is correct for the vehicle. 

Is the correct ECM or PCM installed in the vehicle?

Yes  

Go to 7).  

No  

Replace and program the ECM or PCM in accordance with the Service Information.  

Perform POWERTRAIN VERIFICATION TEST .  

7) VERIFY ECM OR PCM IS PROGRAMMED WITH CORRECT VIN 

With the scan tool, verify that the ECM or PCM is programmed with the correct VIN. 

Is the ECM or PCM programmed with the correct VIN?  

Yes  

Go to 8).  

No  

Using the scan tool, perform PCM Replaced to update the VIN in the PCM.  

Perform POWERTRAIN VERIFICATION TEST .  

8) CHECK FOR ADDITIONAL COMMUNICATION RELATED DTCs 

With the scan tool, select Network View and select Advanced. 

Is there more than one module with active DTCs "Logged Against" the ECM or PCM?  

Yes  

Replace/update the ECM or PCM in accordance with the service information.  

Perform POWERTRAIN VERIFICATION TEST .  

No  

Using the schematics as a guide, check the Anti-Lock Brakes Module pins, terminals, and 
connectors for corrosion, damage, and terminal push out. Pay particular attention to all 
Communication circuits. If no problems are found, replace the Anti-Lock Brakes Module in 
accordance with the Service Information.  

Perform ABS VERIFICATION TEST.
