When Monitored: 

 

2007 Dodge Nitro R/T 

2007 BRAKES ABS - Electrical Diagnostics - Nitro

  

With vehicle speed above 11 km/h (7 mph), but not if the sensor signal is invalid. 

Or, during skidding. 

Or, when driving in reverse. 

Set Condition: 

If the Anti-Lock Brakes Module detects implausible Dynamics Sensor values. 

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. 

Test drive the vehicle by turning the vehicle left or right in a curving manner at a velocity between 10 and 
20 km/h (6 and 12 mph). 

Park the vehicle. 

With the scan tool, read ABS DTCs. 

Does this DTC reset?  

Possible Causes 

WIRING HARNESS, TERMINAL, CONNECTOR DAMAGE
DYNAMICS SENSOR INSTALLATION
DYNAMICS SENSOR

NOTE:

If present, diagnose and repair DTC C2114-DYNAMICS SENSOR SUPPLY 
VOLTAGE LOW or DTC C2115-DYNAMICS SENSOR SUPPLY VOLTAGE 
HIGH before diagnosing this DTC.

WARNING:

Ensure brake capability is available before road testing.

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 THE DYNAMICS SENSOR INSTALLATION 

Turn the ignition off. 

Check the Dynamics Sensor for damaged, modified, and bent mounting brackets. 

Check the Dynamics Sensor mounting bolts for a loose or over tightened condition. 

Were any problems found?  

Yes  

Repair as necessary.  

Perform ABS VERIFICATION TEST.  

No  

Go to 3).  

3) 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. 

Were any problems found?  

Yes  

Repair as necessary.  

Perform ABS VERIFICATION TEST. 

NOTE:

Dynamics Sensor installation and mounting bolt torque is crucial for 
proper operation.

No  

Replace the Dynamics Sensor in accordance with the Service Information.  

Perform ABS VERIFICATION TEST.  

C123F-STEERING ANGLE SENSOR COMPARATIVE PERFORMANCE 

For complete wiring diagrams refer to SYSTEM WIRING DIAGRAMS article. 

When Monitored: 

With ignition on, but not if a checksum failure of the stored offset values is detected. 

Or, a CAN time-out failure is detected. 

Or, a failure is detected by the Steering Angle Sensor. 

Set Condition: 

If the Anti-Lock Brakes Module detects that either the calculated steering wheel angle offset or the 
steering wheel angle signal measured output is out of range. 

Diagnostic Test 

1) PERFORM TEST DRIVE & VERIFY DTC IS STILL ACTIVE 

Turn the ignition on. 

With the scan tool, erase ABS DTCs. 

Cycle the ignition switch. 

Possible Causes 

VEHICLE DAMAGE
STEERING COLUMN/INTERMEDIATE SHAFT DAMAGE
STEERING WHEEL ALIGNMENT
STEERING ANGLE SENSOR LOOSE
STEERING ANGLE SENSOR IMPROPERLY INSTALLED (WRONG MOUNTING POSITION)
STEERING ANGLE SENSOR
ANTI-LOCK BRAKE MODULE

NOTE:

If present, diagnose and repair DTC C1219-STEERING ANGLE SENSOR 
ERRATIC PERFORMANCE, C121A-STEERING ANGLE SENSOR NOT 
INITIALIZED, or C1240-STEERING ANGLE SENSOR OVERTRAVEL 
PERFORMANCE before diagnosing this DTC.
