C0695

DTC C0695

Test 1-9:

Circuit Description
The 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
The ignition ON.

Conditions for Setting the DTC:
^ The ESC module senses position sensor supply voltage under 4.5 volts or over 5.5 volts.
^ The condition must be detected for 1 second in 4 consecutive ignition cycles.

Action Taken When the DTC Sets
^ Stores a DTC C0695 in the ESC memory.
^ Provides shock absorber actuator control based only on the vehicle speed.
^ Sends a message to the IPC to display the SERVICE RIDE CONTROL 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 4.5 - 5.5 volts.
^ The IPC clearing DTCs feature
^ Using a scan tool

Diagnostic Aids
^ The following conditions may cause an intermittent malfunction to occur:
- An intermittent short to ground is detected on any of the position sensor supply circuits.
- An intermittent short to voltage is detected on any of the position sensor supply circuits.
^ The ESC module uses a common power supply in order to provide voltage to all of the position sensors. Therefore, a position sensor overcurrent code may be set if a malfunction is detected on any position sensor supply circuit.
^ The ESC module uses an ignition cycle counter diagnostic approach to set this DTC. This requires the ESC module to detect the malfunction 4 times before setting the DTC. To disable this feature, use a scan tool to clear all DTCs before preforming diagnostic procedures.
^ If any position sensor supply circuit is shorted to ground, the scan tool will indicate all of the position sensor voltage readings as zero.
^ If any position sensor is shorted to voltage, the position sensor will still function properly and the scan tool will display a valid position sensor voltage reading.
^ An intermittent DTC C0695 may produce a random firm/soft condition.

Test Description
The numbers refer to the step numbers on the diagnostic table.
2. This tests the position sensor signal voltage range using a scan tool. The scan tool will display 0 volts for all position sensors if any position sensor 5 volt reference circuit is shorted to ground.
3. This tests if any position sensor is shorted to ground.
4. This tests determines which position sensor is shorted to ground.
5. Tests for a short to ground in the position sensor 5 volt reference circuits.
6. Tests for a short to voltage in the position sensor 5 volt reference circuits.
