Circuit Description
The air suspension adjusts the vehicle suspension ride height. The air suspension control module (ASCM) determines the height of the vehicle based on the signal from the rear height sensors which are supplied a 5-volt reference voltage from the module. The ASCM raises and lowers the vehicle in order to keep the vehicle level.
Conditions for Running the DTC
Ignition is ON.
Conditions for Setting the DTC
The air suspension control module detects that the supplied 5-volt reference voltage circuit for both suspension position sensors falls below 4.75 volts or exceeds 5.25 volts.
Action Taken When the DTC Sets
| • | The air suspension system will be inoperative. |
| • | The SERVICE SUSPENSION SYSTEM message will be displayed. |
Conditions for Clearing the MIL/DTC
| • | When the fault is no longer present, DTC C0696 will change from a current DTC to a history DTC on the next ignition cycle. |
| • | DTC C0696 will be cleared from history after 50 ignition cycles. |

Circuit/System Testing
- Ignition OFF, disconnect both air suspension sensors.
- Test for less than 2.0 ohms between suspension position sensor low reference terminal 3 (LR) and terminal 1 (RR) and ground.
- Ignition ON, test for 4.8-5.2 volts between the sensor 5-volt reference circuit terminal 1 (LR) and terminal 3 (RR) of the harness connectors and ground.
- Ignition OFF, reconnect the LR air suspension sensor.
- Ignition ON, test for 4.75-5.25 volts exists between the RR position sensor 5-volt reference circuit terminal 3 and ground.
- Test or replace RR air suspension sensor that is not connected.
| ⇒ | If greater than the specified range, test the low reference circuit for an open or high resistance. If all circuits test normal, replace the air suspension control module. |
| ⇒ | If less that the specified range, test the 5-volt reference circuit for open/high resistance or a short to ground. If the circuit tests normal, replace the air suspension control module. |
| ⇒ | If greater that the specified range, test the 5-volt reference circuit for a short to voltage. If the circuit tests normal, replace the air suspension control module. |
| ⇒ | If less than the specified range, test or replace the LR air suspension sensor. |
