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.

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.

Open in Stop Light Switch Circuit (C1425)
DESCRIPTION The skid control ECU (brake actuator assembly) detects the brake operating conditions through a signal transmitted by the stop light switch. The skid control ECU incorporates a circuit to detect an open circuit. This DTC is output when an open circuit is detected in the stop light ...

Removal
REMOVAL PROCEDURE 1. DRAIN DIFFERENTIAL OIL 2. REMOVE PROPELLER WITH CENTER BEARING SHAFT ASSEMBLY (for 2WD) 3. REMOVE PROPELLER WITH CENTER BEARING SHAFT ASSEMBLY (for 4WD) 4. REMOVE REAR DRIVE PINION NUT (a) Using SST and a hammer, unstake the nut. SST: 09930-00010 (b) for BD20: ...

Rear Speed Sensor RH Malfunction (C1403,C1404)
DESCRIPTION The speed sensor detects wheel speed and sends the appropriate signals to the skid control ECU (brake actuator assembly). These signals are used for brake control. The speed sensor rotors have rows of alternating N and S magnetic poles and their magnetic fields change when the roto ...
