WARNING
A battery can explode if you do not follow the proper procedure, causing serious injury to anyone nearby. Follow all procedures carefully and keep sparks and open flames away from the battery.
Use an ED-18 Battery Tester, and follow the manufacturer's procedures. If you don't have one of these computerized testers, follow this conventional test procedure:
1. Be sure the temperature of the electrolyte is between 70 ºF (21 ºC) and 100 ºF (38 ºC).
2. Inspect the battery case for cracks or leaks.
3. Check the test indicator window.
4. Apply a 300 amp load for 15 seconds to remove the surface charge.
5. Wait 15 seconds, then apply-a test load of 280 amps for 15 seconds.
6. Record battery voltage.
7. Charge the battery on High (40 amps) until the test indicator window shows the battery is charged, plus an additional 30 minutes. If the battery charge is very low, it may be necessary to bypass the charger's polarity protection circuitry.

Check for continuity between the terminals.
Ignition Switch
Test
SRS components are located in this area. Review the SRS component locations and precautions and procedures before performing repairs or servicing.
1. Make sure you have anti-theft codes for the audio and navigation system. If equipped with XM radio, write down the XM radio presets.
2. Turn the ignition switch OFF, and disconnect the negative battery cable.
3. Remove the driver's dashboard lower cover and the steering column covers.
4. Disconnect the 7P connector (A) from the ignition switch (B).
5. Check for continuity between the terminals in each switch position according to the table.
6. If the continuity checks do not agree with the table, replace the ignition switch.
7. After reconnecting the battery, enter the audio and navigation system anti-theft codes, and set the clock. If equipped with XM radio, enter the XM radio presets.
