Battery Test
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.
Honda Electrical System Analyzer (ED-18 Battery
tester): T/N INBED18LLH
To order an Electrical System Analyzer, go to the Honda
Tool and Equipment catalog on the iN, or call
888-424-6857.
Make sure you have the latest software in the ED-18. To
check the version on the do this:  Press the POWER button.
 Select Reports, then press ENTER.
 Select i Version, then press ENTER.
If you do not have the correct version, Tools Hotline at
800-346-6327.
NOTE: For set up, customization, and other available
features, refer to the ED-18 user’s manual. 1. Connect the leads to the positive and negative terminal of the battery.
2. Use the arrow keys to select the battery test, then press enter, then follow the prompts.
NOTE: Make sure to enter the correct cold cranking
ampere rating of the battery. If the number is not
entered correctly, the result will not be accurate. 3. Here are the five possible battery conditions:
 Good Battery: The battery has at least 60 percentof its charge and requires no action.
 Good-Recharge: The battery condition appears to be good, but charging is recommended and then
retest. See your battery charger’s instructions to
fully charge the battery, then recheck. Do not
charge the battery using the vehicle’s alternator.
 Charge and Retest: The battery condition is not known because its charge is too low. Recharge
the battery, then retest. See your battery’s
instructions to fully charge the battery, then
recheck. Do not charge the battery using the
vehicle’s alternator.
 Replace Battery: The battery condition is poor. Replace it.
 Bad Cell: There is a problem with the battery. Replace it.

Some systems store data in memory that is lost when
the battery is disconnected. Do the following steps
before disconnecting the battery.1. Make sure you have the anti-theft code(s) for the audio and/or the navigation system (if equipped).
2. If you are replacing the audio unit, write down the audio presets (AM and FM), and the XM audio
presets (if equipped), because the audio unit does
not retain the presets after the battery is
disconnected.
3. Make sure the ignition switch is in LOCK (0).
4. Disconnect and isolate the negative cable from the battery.
NOTE: Always disconnect the negative cable from
the battery first.
5. Disconnect the positive cable from the battery. Some systems store data in memory that is lost when
the battery is disconnected. Do the following steps to
restore the systems back to normal operation.
1. Clean the battery terminals.
2. Test the battery (see page 22-67).
3. Reconnect the positive cable (A) to the battery (B) first, then reconnect the negative cable (C) to the
battery.
NOTE: Always connect the positive cable to the
battery first.
4. Apply multipurpose grease to the terminals to prevent corrosion.
5. Enter the anti-theft code(s) for the audio system and/or the navigation system (if equipped).
6. Enter the audio presets (if applicable), and enter the XM audio presets (if equipped).
7. Set the clock (for vehicles without navigation).

NOTE: The battery terminal disconnection/reconnection
procedure (see page 22-68) must be done before and
after doing this procedure. Some systems store data in
memory that is lost when the battery is disconnected.
1. Do the battery terminal disconnection procedure (see page 22-68).
2. Remove the two nuts (A) securing the battery setting plate, then remove the battery setting plate
(B) and the battery (C). 1. Install the battery (A), then install the battery
setting plate (B).
2. Tighten the two nuts (C) equally until the battery is stable.
NOTE: Do not deform the battery setting plate by
over-tightening the nuts.
3. Do the battery terminal reconnection procedure (see page 22-68).
NOTE: Make sure the positive terminal and the
negative terminal are not reverse-c onnected.
