Twelve volts 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 12V battery voltage is detected.
Conditions for Running the DTC
The ignition is ON.
Conditions for Setting the DTC
12V 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 voltage returns to the normal range.
* 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.

Circuit/System Verification
1. Engine running, accessories OFF, measure and record the battery voltage at the 12V battery terminals. The voltage should be between 12.6
and 15.0 volts.
锟斤拷If not within the specified range, refer to Charging System Test (See: Starting and Charging/Testing and Inspection/Component Tests
and General Diagnostics/Charging System Test).
2. Observe the scan tool ESC module Battery Voltage Signal parameter. The reading should be between 12.6 and 15.0 volts.
