(see page 11-7), then recheck. If the symptom goes
away with a known-good PCM, replace the original
PCM (see page 11-228). SRS components are located in this area. Review the
SRS component locations (see page 24-11) and the

Steering Wheel Rotational Play
Check
Power Assist Check
1. Turn the front wheels to the straight ahead position.
2. Measure how far you can turn the steering wheel
left and right without moving the front wheels.
 If the play is within the limit, the steering gearbox and steering linkage are OK.
 If the play exceeds the limit, adjust the rack guide (see page 17-15). If the play is still excessive after
rack guide adjustment, inspect the steering
linkage and steering gearbox (see page 17-5). NOTE: This test should be done with original equipment
tires and wheels at the correct tire pressure.
1. Start the engine, and let it idle.
2. Attach a commercially available spring scale to the steering wheel. With the engine idling and the
vehicle on a clean, dry floor, pull the scale as
shown, and read it as soon as the tires begin to turn.
3. Ifthescalereadsnomorethan34N(3.5kgf,7.7lbf), the power assist is OK. If it reads more, check these
items:
 Steering linkage (see page 17-5)
 Rack guide adjustment (see page 17-15)
 EPS system (see page 17-19)

SRS components are located in this area. Review the
SRS component locations (see page 24-11) and the
precautions and procedures (see page 24-13) before
doing repairs or service.
1. Do the battery terminal disconnection procedure (see page 22-68).
2. Align the front wheels straight ahead, then remove the driver’s airbag from the steering wheel
(see page 24-188).
3. Disconnect the cable reel subharness connector (A).
4. Loosen the steering wheel bolt (B). 5. Install a commercially available steering wheel
puller (A) on the steering wheel (B). Free the
steering wheel from the steering column shaft by
turning the pressure bolt (C) of the puller.
Note these items when removing the steering
wheel: Do not tap on the steering wheel or the steering column shaft when removing the steering wheel.
 If you thread the puller bolts (D) into the wheel hub more than five threads, the bolts will hit the
cable reel and damage it. To prevent this, install
a pair of jam nuts five threads up on each puller
bolt.
6. Remove the steering wheel puller, then remove the steering wheel bolt and steering wheel from the
steering column.
