GENERATOR INSPECTION [AJ] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed))

BME011718300W02

## 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 [AJ].)

  • Replace if necessary.

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

  • If not, inspect generator warning light, wiring harnesses between the battery, generator warning light, and PCM terminal 65. When the generator warning light and the wiring harnesses are normal, 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, P2502, P2503, P2504. (See ON-BOARD DIAGNOSTIC TEST [AJ].)

## Generator

### Voltage

1. Verify that the battery is fully charged.

  • Charge if necessary.

2. Inspect the drive belt deflection/tension. (See DRIVE BELT INSPECTION [AJ].)

  • Replace if necessary.

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 the terminals shown in the table.

  • If there is any malfunction, repair or replace the generator as necessary.

Standard voltage

Terminal | Ignition switch ON(V) | Idle (V) [20 °C {68 °F}]
--- | --- | ---
B | B+ | 13-15
P | Approx. 1 | Approx. 3-8
D | Approx. 0 | *

  * :
Turn the following electrical loads on and verify that the voltage reading increases.
  • Headlights
  • Blower motor
  • Rear window defroster

## Current

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 [AJ].)

  • Replace if necessary.

3. Disconnect the negative battery cable.

4. Connect an ammeter, capable of reading 120 A or more, 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.

  (1) Headlights
  (2) Blower motor
  (3) Rear window defroster

  • If generator terminal B current will not increase, repair or replace the generator as necessary.

  Note

  • Current required for generating power varies with electrical loads applied.

### Standard current (Reference)

Measuring conditions

  Room temperature: 20 °C {68 °F}
  Voltage: 13.5 V
  Engine hot

Engine speed (rpm) | Terminal B current (A)
--- | ---
1,000 | 0*-90
2,000 | 0*-105

  * :
Lower limit of current must be more than 0 A.
