Circuit/System Description

Voltage is supplied to the electronic suspension control (ESC) module by the battery positive (B+) voltage circuit. The ESC module monitors the

supplied voltage to determine if it is within a valid operating range. Damage to components, and incorrect data may occur if the voltage is out of

range. The ESC module disables all outputs, and sets DTC C0895 00, if high or low battery voltage is detected.

Conditions for Running the DTC

The ignition is ON.

Conditions for Setting the DTC

Battery voltage is outside the normal range of 9.0-15.5 volts.

Action Taken When the DTC Sets

The ESC module disables all functionality.

Conditions for Clearing the DTC

* A current DTC will clear when the ESC module receives battery voltage in the normal range of 9-15.5 volts.

* A history DTC will clear if the condition does not return after 50 consecutive ignition cycles.

Diagnostic Aids

* A high or low voltage value in multiple modules indicates a concern in the charging system.

* Overcharging with a battery charger or jump starting can cause this DTC to set.

* Inspect ground connection G400. Verify that it is clean and tight.
