DTC C0625

Step 1 - 4:

Step 5 - 16:

Circuit Description
The Electronic Suspension Control (ESC) module supplies a 5.0 volt reference signal to the suspension position sensor. The suspension position sensor supplies an analog voltage (0.35-4.75 volts) back to the ESC module which represents the position between the body and the wheel. The sensor is also grounded through the ESC module.

Conditions for Running the DTC
The ignition is ON.

Conditions for Setting the DTC
^ The DTC is set when the ESC module measures the position sensor signal voltage below 0.35 volts or above 4.75 volts for more than 1.0 second.
^ The fault is detected during three consecutive ignition cycles, or during the same ignition cycle after clearing the DTC with a scan tool.

Action Taken When the DTC Sets
^ The ESC module will enter the Speed Dependent damping mode.
^ Both Left and Right Normal Force outputs will be set to the default output states.
^ The SERVICE SUSPENSION SYS message will be displayed.

Conditions for Clearing the MIL/DTC
^ The scan tool can be used to clear the DTC.
^ The DTC is saved as history when the ESC module no longer sees voltage outside the normal range. The DTC will clear if the fault does not return during 50 consecutive ignition cycles.

Diagnostic Aids
^ If this fault condition is set along with DTC C0696, diagnose DTC C0696 first.
^ If the DTC is a history DTC, the fault may be intermittent.

Test Description
The numbers refer to the step numbers on the diagnostic table.
3. Tests for the proper operation of the circuit in the low voltage range.
4. Tests for the proper operation of the circuit in the high voltage range. If the fuse in the jumper opens when you perform this test, the signal circuit is shorted to ground.
5. Tests for a short to voltage in the 5 volt reference circuit.
6. Tests for a high resistance or an open in the ground circuit.
