C0895
DTC C0895
Circuit Description
Voltage is supplied to the electronic suspension control (ESC) module in the battery positive voltage circuit and the ignition voltage circuit. The ESC module monitors the supplied voltage to determine if it is within a valid operating range.
DTC Descriptor
This diagnostic procedure supports the following DTC:
DTC C0895 Device Voltage
Conditions for Running the DTC
The ignition is ON.
Conditions for Setting the DTC
The DTC is set when the battery voltage is outside the normal range of 9 - 15.5 volts.
Action Taken When the DTC Sets
Disable All Functionality
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 battery voltage outside the normal range of 9 - 15.5 volts. The DTC will clear if the fault does not return after 50 consecutive ignition cycles.
Diagnostic Aids
DTC C0895 may set when the vehicle is placed on a battery charger, on fast charge, for a long period of time. It may also be set by an intermittent charging system malfunction.
Test Description
The numbers below refer to the step numbers on the diagnostic table.
1. This test determines whether the malfunction is in the supply voltage or the ESC module.
2. Checks for high resistance, a short to ground, or an open in the battery positive voltage circuit.
