Remove the ECM (page 5-73).
Current leakage test
Turn the ignition switch to "OFF", and disconnect the negative (-) cable from the battery.
Connect the ammeter (+) probe to the negative (-) cable and ammeter (-) probe to the battery (-) terminal.
With the ignition switch turned to "OFF", check for current leakage.

When measuring current using a tester, set it to a high range, and then bring the range down to an appropriate level. Current flow higher than the range selected may blow out the fuse in the tester.
While measuring current, do not turn the ignition switch to "ON". A sudden surge of current may blow out the fuse in the tester.
Specified current leakage: 0.1 mA max.
If current leakage exceeds the specified value, a shorted circuit is likely.
Located the short by disconnecting connections one by one and measuring the current.
Charging voltage inspection
Be sure that the battery is in good condition before performing this test.

Start the engine and warm it up to the operating temperature; stop the engine.
Connect the multimeter between the positive and negative terminals of the battery.
Do not disconnect the battery or any cable in the charging system without first switching off the ignition switch. Failure to follow this precaution can damage the tester or electrical components
To prevent a short, make absolutely certain which are the positive and negative terminals of cable.
With the headlight on the high beam, restart the engine.
Measure the voltage on the multimeter when the engine runs at 5,000 rpm.
Standard: Measured battery voltage (page 16-4) < Measured charging voltage (see above) < 15.5 V.
