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

General Troubleshooting Information
NOTE: Check the ECM/PCM for DTCs and troubleshoot ECM/PCM (see page 11-3) or F-CAN loss of communication
errors first.
1. Go to B-CAN System Diagnosis Test Mode A to check for ‘‘Connected units’’ and DTCs (see page 22-93).
2. If no DTCs are retrieved, go to B-CAN System Diagnosis Test Mode C (see page 22-95) or D (see page 22-96).
1. Check for communication circuit problems using B-CAN System Diagnostic Test (see page 22-97).
2. Check for DTCs.
3. Sort, and then troubleshoot the DTCs in the order. –1 Battery voltage DTCs
–2 Internal error DTCs
–3 Loss of communication DTCsNOTE: If the DTC B1000 is stored, troubleshoot DTC B 1000 first.
–4 Signal error DTCs
4. If no DTCs are retrieved, use B-CAN System Diagnostic Test Mode 2 to check all inputs related to failure (see step 10 on page 22-97).
