Diagnostic Instructions
DTC Descriptor
DTC C0696: Position Sensor Overcurrent 5-Volt Supply
Circuit Description
The electronic suspension control (ESC) module provides a common regulated power
supply of 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
The ignition is ON
Conditions for Setting the DTC
| • | The ESC module senses suspension position sensor supply voltage is 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
| • | The ESC module illuminates the LED in the ESC switch |
| • | Commands speed dependent damping system and normal force signals to default
state. |
Conditions for Clearing the DTC
| • | A history DTC will clear after 50 consecutive ignition cycles if the
condition for the malfunction is no longer present |
| • | The ESC module senses the correct sensor supply voltage |
| • | Using a Tech2 Scan tool. |

ESC Malfunction Indicator Lamp
When all DTC's are cleared, and the
Diagnostic System Check - Vehicle
Diagnostic System Check - Vehicle has been performed the
ESC malfunction indicator lamp may stay illuminated for a period of up to 5 seconds
when the ignition switch is moved to the "off" position. The ESC malfunction
indicator lamp should switch off when the ignition is switched to the "on"
position.

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 a known 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
- Disconnect the appropriate sensor.
- Install a 3-A fusible link wire between the 5-volt reference terminal
on the wiring harness and the 5-volt reference terminal on sensor. Install a jumper
wire between the low reference terminal on the sensor and a known ground.
- Connect a DMM between the signal circuit of the sensor and a known ground.
- Sweep the suspension position sensor through the entire range while monitoring
the voltage on the DMM . The range should vary between 0.25-4.75 volts without
any spikes or dropouts.
| ⇒ | If not within the specified range or is erratic, replace the appropriate suspension
position sensor. |
