INSPECTION

PROCEDURE

1. INSPECT GENERATOR BRUSH HOLDER ASSEMBLY

(a) Using a vernier caliper, measure the brush length.

Text in Illustration

Length

Standard exposed length:

9.5 to 11.5 mm (0.374 to 0.453 in.)

Minimum exposed length:

4.5 mm (0.177 in.)

If the brush length is less than the minimum, replace the generator brush holder assembly.

2. INSPECT GENERATOR ROTOR ASSEMBLY

(a) Check that the generator rotor bearing is not rough or worn.

If necessary, replace the generator rotor assembly.

(b) Check the generator rotor assembly for an open circuit.

(1) Measure the resistance according to the value(s) in the table below.

Slip Ring

Standard Resistance:

Generator Assembly Type	Tester Connection	Condition	Specified Condition
for 100A	Slip ring - Slip ring	20°C (68°F)	1.8 to 2.2 Ω
for 130A	Slip ring - Slip ring	20°C (68°F)	1.55 to 1.95 Ω

If the result is not as specified, replace the generator rotor assembly.

(1) Measure the resistance according to the value(s) in the table below.

*a	Slip Ring
*b	Rotor Core

Standard Resistance:

Tester Connection	Condition	Specified Condition
Slip ring - Rotor core	Always	10 MΩ or higher

If the result is not as specified, replace the generator rotor assembly.

(d) Using a vernier caliper, measure the slip ring diameter.

Diameter

Standard diameter:

14.2 to 14.8 mm (0.559 to 0.583 in.)

Minimum diameter:

14.0 mm (0.551 in.)

If the diameter is less than the minimum, replace the generator rotor assembly.

Power Source Mode does not Change to ON (IG and ACC)
DESCRIPTION If any of the following operations are performed, the certification ECU (smart key ECU assembly) receives a signal, and changes the power source mode. With the electrical key transmitter sub-assembly in the cabin, the engine switch is pressed. When the battery of the e ...

If a warning light turns on or a warning buzzer sounds
Calmly perform the following actions if any of the warning lights turn on or flash. If a light turns on or flashes, but then turns off, this does not necessarily indicate a malfunction in the system. Stop the vehicle immediately. Continuing to drive the vehicle may be dangerous. The following ...

Input Speed Sensor Circuit No Signal (P0717,P07BF,P07C0)
DESCRIPTION This sensor detects the rotation speed of the turbine which shows the input turbine speed of the transmission. By comparing the input turbine speed signal (NT) with the output shaft speed sensor signal (SP2), the ECM detects the shift timing of the gears and appropriately controls ...
