replace the ESC module.
瀚慖f greater than the specified range, test the 5 volt reference circuit for a short to voltage. If the circuit tests normal, replace the ESC
module.
4. Verify the applicable scan tool position sensor parameter is less than 0.35 volts.
瀚慖f greater than the specified range, test the signal circuit terminal B for a short to voltage. If all circuits test normal replace the ESC
module.
5. Install a 3A fused jumper wire between the signal circuit terminal B and the 5 volt reference circuit terminal A. Verify the scan tool position
sensor parameter is greater than 4.75 volts.
瀚慖f less that the specified range, test the signal circuit for a short to ground or an open high resistance. If all circuits test normal replace the
ESC module.
6. If all circuits test normal, test or replace the applicable suspension position sensor.
Component Testing
1. Install a 3A fused jumper wire between the 5 volt reference terminal A and 5 volts. Install a jumper wire between the low reference terminal
C and ground.
2. Sweep the suspension position sensor through the entire range while monitoring the voltage between the signal terminal B and the low
reference terminal C. The range should vary between 0.35-4.75 volts without any spikes or dropouts.
瀚慖f not within the specified range or if it is erratic, replace the applicable suspension position sensor.
Repair Instructions
* Electronic Suspension Front Position Sensor Replacement (See: Sensors and Switches/Sensors and Switches - Steering and
Suspension/Sensors and Switches - Suspension/Ride Height Sensor/Service and Repair/Electronic Suspension Front Position Sensor
Replacement)

Suspension/Sensors and Switches - Suspension/Ride Height Sensor/Service and Repair/Electronic Suspension Rear Position Sensor
Replacement - Left Side)
* Electronic Suspension Rear Position Sensor Replacement - Right Side (See: Sensors and Switches/Sensors and Switches - Steering and
Suspension/Sensors and Switches - Suspension/Ride Height Sensor/Service and Repair/Electronic Suspension Rear Position Sensor

)/Service and Repair/Suspension Position Calibration (With Z95))Suspension Position Calibration (Without Z95) (See: Steering and
Suspension/Suspension/Suspension Control ( Automatic - Electronic )/Service and Repair/Suspension Position Calibration (Without Z95))
* Control Module References (See: Testing and Inspection/Programming and Relearning) for ESC replacement, setup, and programming
Repair Verification
1. Install any components or connectors that have been removed or replaced during diagnosis.
2. Perform any adjustment, programming or setup procedures that are required when a component or module is removed or replaced.
3. Clear the DTCs.
4. Use the scan tool Diagnostic Counter Reset output control function to bypass the 3 consecutive ignition cycle requirement for setting a DTC.
This will ensure that if a DTC was to be reset during the repair verification process, it will be displayed on the scan tool.
5. Turn OFF the ignition for 60 seconds.
6. Turn ON the ignition.
7. If the repair was related to a DTC, duplicate the Conditions for Running the DTC and use the Freeze Frame/Failure Records, if applicable, in
order to verify the DTC does not reset. If the DTC resets or another DTC is present, refer to the Diagnostic Trouble Code (DTC) List -
Vehicle (See: Diagnostic Trouble Code Descriptions/Diagnostic Trouble Code (DTC) List - Vehicle) and perform the appropriate diagnostic
procedure.
