ON-VEHICLE INSPECTION
PROCEDURE
1. CHECK STEERING EFFORT (TORQUE)
NOTICE:
Some of these service operations may affect the SRS airbags. Read the precautionary notices concerning the SRS airbag system before servicing.
(a) Stop the vehicle on a level, paved surface and align the wheels straight ahead.
(b) Disconnect the cable from the negative (-) battery terminal.
CAUTION:
Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.
NOTICE:
When disconnecting the cable, some systems need to be initialized after the cable
is reconnected (See page
).
(c) Remove the steering pad (See page
).
(d) Connect the cable to the negative (-) battery terminal.
(e) Using a torque wrench, check that the steering wheel set nut is properly tightened.
Torque:
50 N·m {510 kgf·cm, 37 ft·lbf}
(f) Start the engine so that the power steering is ready to operate.
(g) Turn the steering wheel 90 degrees to the right and check the steering effort (torque) while continuing to turn it further in the same direction.
Steering effort (Reference):
6.9 N*m (70 kgf*cm, 61 in.*lbf) or less
(h) Align the front wheels facing straight ahead.
(i) Turn the ignition switch off.
(j) Disconnect the cable from the negative (-) battery terminal.
CAUTION:
Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.
(k) Install the steering pad (See page
).
(l) Connect the cable to the negative (-) battery terminal.
NOTICE:
When disconnecting the cable, some systems need to be initialized after the cable
is reconnected (See page
).
(m) Clear the DTCs (See page
).
(n) Inspect the airbag warning light (See page
).
Diagnostic Trouble Code Chart
Lost Communication with ECM / PCM "A" (U0100,U0129)Air Mix Damper Control Servo Motor Circuit (Driver Side) (B1446/46)
DESCRIPTION
The air mix control servo motor sends pulse signals to indicate the damper position
to the A/C amplifier. The A/C amplifier activates the motor (normal or reverse)
based on these signals to move the air mix damper (driver side) to any position ...
Compressor Lock Sensor Circuit (B1422/22)
SYSTEM DESCRIPTION
The ECM sends the engine speed signal to the A/C amplifier via CAN communication.
The A/C amplifier reads the difference between compressor speed and engine speed.
When the difference becomes too large, the A/C amplifier determines that ...
Power Source Control ECU Malfunction (B2782)
DESCRIPTION
The power management control ECU controls the power supply to activate the steering
lock motor. This prevents the steering wheel from being locked while the vehicle
is moving.
DTC No.
