CHECK FOR ENGINE BRAKE SWITCH DTCS
With the scan tool, check for engine brake switch DTCs.
Are there any engine brake switch DTCs present?
Yes
>> Refer to the engine Diagnosis and Testing category and perform the appropriate symptom.
Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
No
>> Go To 4
4.
CHECK OTHER CONTROLLERS FOR BRAKE SWITCH DTCS
With the scan tool check other controllers for Brake Switch DTCs.
Do any other controllers report a Brake Switch DTC?
Yes
>> Refer to the Engine Diagnosis and Testing category and perform diagnostics for P0571 as though the
DTC is active.
Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
No
>> Using the schematics as a guide, check the terminals for corrosion, damage, or terminal push out. Pay
particular attention to all power and ground circuits. Check for any Service Bulletins for possible causes
that may apply. If no problems are found, replace the Anti-Lock Brake Module per the Service Informa-
tion.
Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).

•
Set Condition:
Longitudinal acceleration sensor signal is out of range.
Possible Causes
WIRING HARNESS, TERMINAL, CONNECTOR DAMAGE
(G4) DYNAMICS SENSOR SUPPLY HIGH RESISTANCE

ANTI-LOCK BRAKES MODULE
Diagnostic Test
1.
CHECK FOR A DTC C1210–G SENSOR INPUT CIRCUIT PERFORMANCE
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 DTCs.
With the scan tool, read and record Freeze Frame information.
With the scan tool, erase DTCs.
Cycle the ignition switch from off to on.
With the scan tool, read and record DTCs.
Does the scan tool display: C1210–G SENSOR INPUT CIRCUIT PERFORMANCE?
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 TEST. (Refer to 5 - BRAKES - DIAGNOSIS AND TEST-
ING)
2.
CHECK THE TERMINALS/CONNECTORS/WIRING HARNESS FOR DAMAGE
Check the Steering Angle Sensor installation.
Check all related wiring for bruised, chafed, pierced, or partially broken wires.
Check all related connectors for broken, bent, pushed out, or corroded terminals.
Were any problems found?
Yes
>> Repair as necessary.
Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
No
>> Go To 3

3.
(G4) DYNAMICS SENSOR SUPPLY HIGH RESISTANCE
Turn the ignition off.
Disconnect the Dynamics Sensor harness connector.
Turn the ignition on.
Measure the voltage of the (G4) Dynamics Sensor Supply circuit at the
Dynamics Sensor harness connector.
Is the voltage above 10 volts?
Yes
>> Go To 4
No
>> Repair the (G4) Dynamics Sensor Supply circuit for high
resistance.
Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES -
STANDARD PROCEDURE).
4.
(G94) GROUND CIRCUIT HIGH RESISTANCE
Turn the ignition off.
Measure the resistance between the (G94) Ground circuit and ground.
Is the resistance below 5.0 ohms?
Yes
>> Go To 5
No
>> Repair the (G94) Ground circuit for high resistance.
Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES -
STANDARD PROCEDURE).
5.
CHECK THE DYNAMICS SENSOR INSTALLATION
NOTE: Dynamics Sensor installation and mounting bolt torque is crucial for proper operation.
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. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
No
>> Replace the Dynamics Sensor in accordance with the Service Information.
Perform ABS VERIFICATION TEST. (Refer to 5 - BRAKES - STANDARD PROCEDURE).
