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.

Ignition is ON.

The DTC is set when the battery voltage is outside the normal range of 9-15.5 volts.

Disable All Functionality

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.

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.

Electrical Information Reference

1. If the DTC is history, refer to Charging System Test .
2. If the DTC is current, turn ON the ignition, and with a DMM, measure the voltage between the battery positive voltage circuits of the ESC and the ground circuits of the ESC.

⇒	If the voltage is within 9.5-15 volts, replace the ESC.

⇒	If the voltage is not within 9.5-15 volts, measure the voltage between the battery positive voltage circuits of the ESC and a separate good ground.

⇒	If the voltage is within 9.5-15 volts, test the battery positive ground circuits of the ESC for high resistance or an open, and repair as necessary.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
