The following items must be initialized for normal system operation after such cases as the battery being reconnected, or maintenance being performed on the vehicle:

Customization
For ownersBlower resistor
On-vehicle inspection
Inspect blower motor control
Measure the resistance of the blower resistor.
Standard resistance
If the resistance is not as specified, replace the

Data list / active test
Active test
Hint:
Performing the intelligent tester active test allows
relay, vsv, actuator and other items to be operated
without removing any parts. Performing the active
test early in troubleshooting is one way to save time.
The data list can be displayed during the active
test.

Power supply relay failure
Description
If the power steering ecu detects these dtcs, it shuts off the motor relay
circuit (built into the power
steering ecu) and stops power assist.
Inspection procedure
Reconfirm dtc
Check for dtc.
Ok:
dtc is not output.
Replace power steering ecu ...
