For a complete wiring diagram, refer to the Wiring Information.
When Monitored:
With the ignition on.
Set Condition:
If the Dynamics Sensor status changes from initialized to not initialized due to low voltage on the (G4) Dynamics Sensor Supply circuit.
Possible Causes
WIRING HARNESS, TERMINAL, CONNECTOR DAMAGE
(G4) DYNAMICS SENSOR SUPPLY CIRCUIT HIGH RESISTANCE
(G94) DYNAMICS SENSOR GROUND CIRCUIT HIGH RESISTANCE
DYNAMICS SENSOR
ANTI-LOCK BRAKES MODULE
1.
CHECK FOR A
DTC C2114-DYNAMICS SENSOR SUPPLY VOLTAGE LOW
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 the DTCs.
3.
With the scan tool,
read and record the Environmental Data to help identify the conditions
in which the DTC was set.
4.
With the scan tool,
erase the DTCs.
5.
Start the engine.
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.
6.
With the scan tool,
read and record the DTCs.
Does
the scan tool display: C2114-DYNAMICS SENSOR SUPPLY VOLTAGE LOW?
4.
CHECK (G4) DYNAMICS
SENSOR SUPPLY CIRCUIT FOR HIGH RESISTANCE
1.
Turn the ignition
off.
2.
Disconnect the
Anti-Lock Brakes 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.
5.
CHECK (G94)
DYNAMICS SENSOR GROUND CIRCUIT FOR HIGH RESISTANCE
1.
Measure the resistance
of the (G94) Dynamics Sensor Ground circuit between the Dynamics Sensor
harness connector and the Anti-Lock Brake Module harness connector.
Is the
resistance below 5.0 Ohms?
Yes
Replace the Anti-Lock
Brake Module in accordance with the Service Information.
