Battery positive voltage with load
Back-up Current
1. Verify that the ignition switch is off and that the ignition key has been removed.
2. Disconnect the negative battery cable.
Caution
••••
Operating electrical loads while measuring the back-up current can damage the circuit tester.
3. Measure the back-up current between the negative battery terminal and the negative battery cable.
(1) If the current exceeds the maximum, remove the fuse in the main fuse block and the fuse block one by one
while measuring the back-up current.
(2) Inspect and repair harnesses and connectors of the fuse at which the current reduces.
Back-up current
20 mA max.

BATTERY RECHARGING
Warning
••••
Hydrogen gas is produced during normal battery operation. A battery-related explosion can cause
serious injury. Keep all flames (including cigarettes), heat, and sparks away from the top and
surrounding area of open battery cells.
Caution
••••
When disconnecting the battery, remove the negative cable first and install it last to prevent
damage to electrical components or the battery.
••••
To prevent damage to electrical components or the battery, turn all accessories off and stop the
engine before performing maintenance or recharging the battery.
••••
Do not quick charge for over 30 minutes. It will damage the battery.
1. Place a battery in a pan of water to prevent it from
overheating. The water level should come up
about halfway on the battery. Keep water off the
top of the battery.
2. Connect a battery charger to the battery.
3. Adjust the charging current as follows.
4. After the battery has been recharged, measure
the battery positive voltage and verify that the
battery keeps specified voltage for more than 1 hour.
•
If not as specified, replace the battery.

GENERATOR REMOVAL/INSTALLATION
A3U011718300W01
Warning
••••
When the battery cables are connected, touching the vehicle body with generator terminal B will
generate sparks. This can cause personal injury, fire, and damage to the electrical components.
Always disconnect the battery before performing the following operation.
1. Disconnect the negative battery cable.
2. Remove in the order indicated in the table.
3. Install in the reverse order of removal.
Drive Belt Installation Note
•
Install the drive belt and adjust the drive belt deflection or tension. (See 01–10A–4 DRIVE BELT
ADJUSTMENT [ZM].) (See 01–10B–4 DRIVE BELT ADJUSTMENT [FS].)

GENERATOR INSPECTION
A3U011718300W02
Generator Warning Light
1. Verify that the battery is fully charged.
•
Charge if necessary.
2. Verify that the drive belt deflection/tension is within the specification. (See 01–10A–3 DRIVE BELT
INSPECTION [ZM].) (See 01–10B–3 DRIVE BELT INSPECTION [FS].)
•
Adjust if necessary.
3. Turn the ignition switch to ON and verify that the generator warning light comes on.
•
If not, inspect generator warning light, wiring harnesses between the battery, generator warning light, and
PCM terminal 42. When the generator warning light and the wiring harnesses are okay, replace the PCM.
4. Verify that the generator warning light goes out after the engine is started.
•
If not, inspect if any of the following DTCs are displayed: P0112, P0113, P1631, P1632, P1633, P1634.
