Generator Warning Light

1. Verify that the battery is fully charged.

• Charge if necessary.

2. Verify that the drive belt deflection/tension is correct. (See DRIVE BELT INSPECTION [LF, L3].)

• If not as specified, replace the drive belt.

3. Turn the ignition switch to ON position and verify that the generator warning light illuminates.

• If not as specified, inspect the generator warning light.

4. Verify that the generator warning light turns off after the engine is started.

• If not specified, inspect if any of the DTCs is displayed: P0112, P0113, P2502, P2503, P2504

Generator

Voltage

1. Verify that the battery is fully charged.

2. Verify that the drive belt deflection/tension is correct. (See DRIVE BELT INSPECTION [LF, L3].)

• If not as specified, replace the drive belt.

3. Turn off all electrical loads.

4. Turn the ignition switch to start the engine and verify that the generator rotates smoothly without any noise while the engine is running.

5. Measure the voltage at each terminals.

• If not as specified, repair or replace the generator if necessary.
Generator standard voltage [IG-ON]
Terminal B: B+
Terminal P: Approx. 1 V
Terminal D: Approx. 0 V
Generator standard voltage [Idle, 20 °C {68 °F}]
Terminal B: 13-15 V
Terminal P: Approx. 3-8 V
Terminal D: Turn the electrical loads (headlights, blower motor, rear window defroster) on and verify that the voltage reading increases.

Current

1. Verify that the battery is fully charged.

• If the battery is not fully charged, charge the battery.

2. Verify that the drive belt deflection/tension is correct. (See DRIVE BELT INSPECTION [LF, L3].)

• If not as specified, replace the drive belt.

3. Disconnect the negative battery cable.

4. Connect an ammeter, capable of reading 120 A or above, between generator terminal B and the wiring harness.

5. Connect the negative battery cable.

6. Turn off all electrical loads.

7. Start the engine and increase the engine speed to 2,000-2,500 rpm.

8. Turn the following electrical loads on and verify that the current reading increases.

• Headlights
• Blower motor
• Rear window defroster
Note
• Current required for generating power varies with electrical loads applied.
