Circuit/System Description
The electronic suspension control (ESC) module provides a common regulated reference voltage of approximately 5 volts to all of the position sensors. The ESC module monitors this power supply for a malfunction that could prevent it from correctly regulating the supply voltage.
Conditions for Running the DTC
| • | Battery voltage is between 9-16 volts. |
| • | Ignition is ON. |
Conditions for Setting the DTC
| • | The ESC module senses suspension position sensor supply voltage under 4.75 volts or over 5.25 volts. |
| • | The condition is detected for 1 second in 4 consecutive ignition cycles. |
Action Taken When the DTC Sets
| • | Commands speed dependent damping system and normal force signals to the default state. |
| • | The ESC sends a message to the instrument panel cluster (IPC) to display SERVICE SUSPENSION SYSTEM message. |
Conditions for Clearing the DTC
| • | A history DTC will clear after 100 consecutive ignition cycles if the condition for the malfunction is no longer present. |
| • | The ESC module senses the correct sensor supply voltage. |
| • | The IPC clearing DTC feature. |

Circuit/System Verification
Ignition ON, observe the scan tool Position Sensor Data parameters while the vehicle is jounced. The readings should vary between 0.35-4.75 volts.
Circuit/System Testing
- Ignition OFF, disconnect the harness connector at all 4 suspension position sensors.
- Ignition ON, test for 4.8-5.2 volts between the 5-volt reference circuit terminal A and ground at each sensor connector.
- Test for less than 0.35 volts between the signal circuit terminal B and ground.
- Reinstall each sensor one at a time. Test for 4.8-5.2 volts between the 5-volt reference circuit terminal A and ground of the last sensor to be connected.
- Test or replace the last remaining suspect suspension position sensor.
Important: Whenever repairing and/or replacing ALC system components, perform the Suspension Position Calibration procedure.
| ⇒ | If less than the specified range, test the 5-volt reference circuit for a short to ground or an open/high resistance. If all circuits test normal, replace the ESC module. |
| ⇒ | If greater than the specified range, test the 5-volt reference circuit for a short to voltage. If the circuits test normal, replace the ESC module. |
| ⇒ | If greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the ESC module. |
| ⇒ | If the voltage is not within the specified range when one of the 3 sensors are connected, test or replace the suspect suspension position sensor. |
Component Testing
- 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.
- 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.
| ⇒ | If not within the specified range or if it is erratic, replace the appropriate suspension position sensor. |

Repair Verification
- Install any components or connectors that have been removed or replaced during diagnosis.
- Perform any adjustment, programming or setup procedures that are required when a component or module is removed or replaced.
- Clear the DTCs.
- 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.
- Turn OFF the ignition for 60 seconds.
- Turn ON the ignition.
- If the repair was related to a DTC, duplicate the Conditions for Running the DTC and use the Freeze Frame/Failure Records, if appropriate, 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 and perform the appropriate diagnostic procedure.
