Verify DTC Is Active

VERIFY DTC IS ACTIVE
NOTE:
The Sensor Cluster is the same as the Dynamics sensor.

NOTE:
This DTC must be active for the results of this test to be valid.
1. Turn the ignition on.
2. With the scan tool, read and record ABS DTCs.
3. With the scan tool, read and record Environmental Data to help identify the conditions in which the DTC was set.
4. With the scan tool, erase ABS DTCs.
5. Cycle the ignition switch.
6. With the scan tool, read ABS DTCs.
  NOTE:
  Attempt to operate the vehicle under conditions similar to which the DTC was set. It may be necessary to test drive the vehicle within the DTC monitoring and set conditions in order for this DTC to set.
  
  Does this DTC reset?
  
  Yes
  - Go To 2
  No
  - Perform the ABS-INTERMITTENT CONDITION TEST. Refer to ABS-INTERMITTENT CONDITION .
INSPECT RELATED WIRING HARNESS, TERMINALS, AND CONNECTORS
1. Turn the ignition off.
2. Check all related wiring for pinched, chafed, pierced, and partially broken wires.
3. Check all related connectors for broken, bent, pushed out, and corroded terminals.
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Perform ABS VERIFICATION TEST. Refer to ABS VERIFICATION TEST .
  No
  - Go To 3

1. Disconnect the Dynamics Sensor harness connector.
2. Turn the ignition on.
3. Measure the voltage between the (G4) Dynamics Sensor Supply Circuit and the (G94) Dynamics Sensor Ground Circuit.
  Is the voltage above 10 volts?
  
  Yes
  - Replace the Dynamics Sensor in accordance with the Service Information.
  - Perform ABS VERIFICATION TEST. Refer to ABS VERIFICATION TEST .
  No
  - Go To 4
CHECK (G4) DYNAMICS SENSOR SUPPLY CIRCUIT FOR HIGH RESISTANCE

1. Turn the ignition off.
2. Disconnect the Anti-Lock Brake Module harness connector.
3. Measure the resistance of the (G4) Dynamics Sensor Supply circuit between the Dynamics Sensor harness connector and the Anti-Lock Brake Module harness connector.
  Is the resistance below 5.0 ohms?
  
  Yes
  - Go To 5
  No
  - Repair the (G4) Dynamics Sensor Supply circuit for high resistance.
  - Perform ABS VERIFICATION TEST. Refer to ABS VERIFICATION TEST .
