Toyota Sienna Service Manual: Inspection
1. Inspect generator clutch pulley
(a) Hold the center of the pulley, and confirm that the outer ring turns counterclockwise and does not turn clockwise.
If the result is not as specified, replace the clutch pulley.
2. Remove generator drive end frame bearing
(a) Check that the bearing is not rough or worn.V
Ok: the bearing rotates smoothly.
If the bearing does not rotate smoothly, replace the bearing.
3. Inspect generator brush holder assembly
(a) Using vernier calipers, measure the length of the exposed brushes.
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 exposed length is less than the minimum, replace the brush holder assembly.
4. 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 for an open circuit.
(1) Using an ohmmeter, measure the resistance between the slip rings.
Standard resistance
If the result is not as specified, replace the generator rotor assembly.
(c) Check the rotor for a short to ground.
(1) Using an ohmmeter, measure the resistance between the slip ring and rotor.
Standard resistance 
If the result is not as specified, replace the generator rotor assembly.
(d) Using vernier calipers, measure the slip ring diameter.
Standard diameter: 14.2 to 14.4 mm (0.559 to 0.567 in.) Minimum diameter: 14.0 mm (0.551 in.)
If the diameter is less than the minimum, replace the generator rotor assembly.

DTC P0607 Control Module Performance
DESCRIPTION
The ECM continuously monitors its main and sub CPUs. This self-check ensures
that the ECM is
functioning properly. If outputs from the CPUs are different and deviate from
the standards, the ECM will
illuminate the MIL and set a DTC immediately ...
Cold Start Ignition Timing Performance
DTC P050B Cold Start Ignition Timing Performance
DESCRIPTION
This monitor will run when the engine is started at -10 to 50C (14 to 122F)
of the engine coolant
temperature. The DTC will set after the engine idling for 13 seconds (2 trip
detection logic).
The DTC is designed to monitor the i ...
