6. While viewing the battery test result, press the CODE button and the tester will prompt you for the last 4 digits
of the VIN. Use the UP/DOWN arrow buttons to scroll to the correct character; then press ENTER to select and
move to the next digit. Then press the ENTER button to view the SERVICE CODE. Pressing the CODE button
a second time will return you to the test results.

STANDARD PROCEDURE - OPEN-CIRCUIT VOLTAGE TEST

A battery open-circuit voltage (no load) test will show the approximate state-of-charge of a battery. This test can be
used in place of the hydrometer test when a hydrometer is not available, or for maintenance-free batteries with
non-removable cell caps.
Before proceeding with this test, completely charge the battery. (Refer to 8 - ELECTRICAL/BATTERY SYSTEM/
BATTERY - STANDARD PROCEDURE).
1. Before measuring the open-circuit voltage, the surface charge must be removed from the battery. Turn on the
headlamps for fifteen seconds, then allow up to five minutes for the battery voltage to stabilize.
2. Disconnect and isolate both battery cables, negative cable first.
3. Using a voltmeter connected to the battery posts (see the instructions provided by the manufacturer of the volt-
meter), measure the open-circuit voltage.
See the Open-Circuit Voltage Table. This voltage reading will indicate the battery state-of-charge, but will not reveal
its cranking capacity. If a battery has an open-circuit voltage reading of 12.4 volts or greater, it may be load tested
to reveal its cranking capacity. (Refer to 8 - ELECTRICAL/BATTERY SYSTEM/BATTERY - STANDARD PROCE-
DURE).

STANDARD PROCEDURE - IGNITION-OFF DRAW TEST

The term Ignition-Off Draw (IOD) identifies a normal condition where power is being drained from the battery with
the ignition switch in the Off position. A normal vehicle electrical system will draw from five to thirty-five milliamperes
(0.005 to 0.035 ampere) with the ignition switch in the Off position, and all non-ignition controlled circuits in proper
working order. Up to thirty-five milliamperes are needed to enable the memory functions for the Powertrain Control
Module (PCM), and other modules which may vary with the vehicle equipment.
A vehicle that has not been operated for approximately twenty days, may discharge the battery to an inadequate
level. When a vehicle will not be used for twenty days or more (stored), remove the negative battery cable from the
battery. This will reduce battery discharging.
Excessive IOD can be caused by:
• Electrical items left on.
• Faulty or improperly adjusted switches.
