C123C

C123C-DYNAMICS SENSOR MOUNTING/INSTALLATION PERFORMANCE









When Monitored:

With the ignition on.

Set Condition:

When the Anti-Lock Brake Module indicates the Dynamics Sensor values are invalid.






1. CHECK FOR A DTC C123C-SENSOR CLUSTER MOUNTING/INSTALLATION PERFORMANCE

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

Turn the ignition on.
With the scan tool read and record DTC's.
With the scan tool read and record Freeze Frame information.
With the scan tool erase DTC's.
Cycle the ignition switch from off to on.
With the scan tool read and record DTC's

Does the scan tool display: C123C-SENSOR CLUSTER MOUNTING/INSTALLATION PERFORMANCE?

Yes

- Go To 2

No

- Refer to the INTERMITTENT CONDITION diagnostic procedure.
- Perform ABS VERIFICATION TEST VER 1.

2. CHECK THE WIRING HARNESS, TERMINALS, AND CONNECTORS

Turn ignition off.
Visually inspect the related wiring harness. Look for any bruised chafed pierced or partially broken wires.
Visually inspect the related wiring harness connectors. Look for broken bent pushed out or corroded terminals.

Were any problems found?

Yes

- Repair as necessary.
- Perform ABS VERIFICATION TEST = VER 1.

No

- Go To 3

3. CHECK THE DYNAMICS SENSOR INSTALLATION

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

Check the Dynamics Sensor for damaged modified or bent mounting bracket.
Check the Dynamics Sensor mounting bolts for loose or over tightened mounting bolts.

Were any problems found?

Yes

- Repair as needed.
- Perform ABS VERIFICATION TEST = VER 1.

No

- Go To 4

4. CHECK THE RESISTANCE BETWEEN THE (G94) DYNAMICS SENSOR GROUND CIRCUIT AND GROUND

Disconnect the Dynamics Sensor harness connector. Measure the resistance between the (G94) Dynamics Sensor Ground circuit and ground.

Is the resistance below 5.0 ohm?

Yes

- Replace the Dynamics Sensor.
- Perform ABS VERIFICATION TEST - VER 1.

No

- Repair the (G94) Dynamics Sensor Ground circuit for an open circuit.
- Perform ABS VERIFICATION TEST VER 1.
