DTC C0895 HSV
Diagnostic Instructions
DTC Descriptor
DTC C0895: Device Voltage
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.
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
| • | The ESC module illuminates the LED in the ESC switch. |
| • | Disables all Functionality. |
Conditions for Clearing 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. |
| • | Using a Tech2 Scan tool. |
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.

ESC Malfunction Indicator Lamp
When all DTC's are cleared, and the
Diagnostic System Check - Vehicle
has been performed the ESC malfunction indicator lamp
may stay illuminated for a period of up to 5 seconds when the ignition switch is moved
to the "off" position. The ESC malfunction indicator lamp should switch
off when the ignition is switched to the "on" position.

Circuit/System Testing
- 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 module and the ground
circuits of the ESC module.
| ⇒ | If the voltage is within 9.5-15 volts, replace the ESC module. |
| ⇒ | If the voltage is not within 9.5-15 volts, measure the voltage between the battery
positive voltage circuits of the ESC module and a known ground. |
| ⇒ | If the voltage is within 9.5-15 volts, test the battery positive ground circuits
of the ESC module for an open/high resistance. Repair as necessary. |
