Automatic Level Control
DTC C0696
Circuit Description
The automatic level control (ALC) module provides 5 volts to the position sensor. The ALC sensor also monitors this voltage supply for a fault condition which prevents proper regulation. The control module is internal to the ALC sensor. No external circuits are involved.
DTC Descriptor
This diagnostic procedure supports the following DTC:
DTC C0696 Position Sensor Overcurrent (5 volt supply)
This vehicle has DTCs which include DTC Symptoms. For more information on DTC Symptoms, refer to DTC Symptom Description.
Conditions for Running the DTC
The ignition is ON.
Conditions for Setting the DTC
* The position sensor supply voltage is outside the valid range of 4.75-5.25 volts.
* The fault is detected for 1 second or more during ignition cycles, or during the same ignition cycle after clearing the DTC with a scan tool.
Action Taken When the DTC Sets
* The ALC sensor will set a current DTC
* The SERVICE SUSPENSION SYS messages will be displayed
* The ALC system will not operate
Conditions for Clearing the MIL/DTC
* The scan tool can be used to clear the DTC.
* The DTC is saved as history when the ALC sensor no longer sees a position sensor supply voltage outside the valid range of 4.75-5.25 volts. The DTC will clear if the fault does not return after 50 consecutive ignition cycles.
Diagnostic Aids
* The control module is internal to the ALC sensor, and no external circuits are involved. If DTC C0696 sets, and cannot be cleared, replace the ALC sensor.
* If DTC C0696 is stored in history, Refer to Testing for Intermittent Conditions and Poor Connections. Component Tests and General Diagnostics
