Dodge Nitro. Manual - part 211

If the Anti-Lock Brakes Module detects too many CAN Bus off events on the Dynamics Sensor Data 
Link circuits. 

Diagnostic Test 

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) INSPECT RELATED WIRING HARNESS, TERMINALS, & CONNECTORS 

Visually inspect the related wiring harness. Look for any pinched, chafed, pierced, and partially broken 
wires. 

Visually inspect the related wiring harness connectors. Look for broken, bent, pushed out, and corroded 
terminals.

Disconnect the Dynamics Sensor harness connector.

Turn the ignition on. 

Measure the voltage of the (D52) Dynamics Sensor High Data Link circuit. 

Is there any voltage present?  

Yes  

Repair the (D52) Dynamics Sensor High Data Link circuit for a short to voltage.  

Perform ABS VERIFICATION TEST.  

No  

Go to 4).  

4) CHECK THE (D52) DYNAMICS SENSOR HIGH DATA LINK CIRCUIT FOR A SHORT TO 
GROUND

Turn the ignition off. 

Measure the resistance of the (D52) Dynamics Sensor High Data Link circuit between ground and the 
Dynamics Sensor harness connector. 

Is the resistance below 5.0 ohms?  

Yes  

Repair the (D52) Dynamics Sensor High Data Link circuit for a short to ground.  

Perform ABS VERIFICATION TEST.  

No
