DTC Descriptor
DTC C0696: Position Sensor Overcurrent (5-volt supply)
Circuit/System Description
The electronic suspension control (ESC) module provides a common regulated power supply of about 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
Ignition ON.
Conditions for Setting the DTC
| • | The ESC module senses suspension position sensor supply voltage under 4.8 volts or over 5.2 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 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 parameter. The reading should be between 4.8-5.2 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 and ground.
| ⇒ | If less than the specified range, test the 5-volt reference circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the ESC module. |
| ⇒ | If 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. |
- Reinstall each sensor one at a time while monitoring DTCs.
| ⇒ | If DTC resets, replace the suspect suspension position sensor. |
| ⇒ | If 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. |
- If all circuits test normal, replace the applicable suspension position sensor.
Component Testing
Dynamic Test
- Install a 3A fused jumper wire between the 5-volt reference terminal and 5 volts. Install a jumper wire between the low reference terminal and ground.
- Sweep the suspension position sensor through the entire range while monitoring the voltage between the signal terminal and the low reference terminal. The range should vary between 0.35-4.75 volts without any spikes or dropouts.
| ⇒ | If not within the specified range or is erratic, replace the applicable suspension position sensor. |
Repair Instructions
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 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
and perform the appropriate diagnostic procedure.
