●Start engine. With engine at idle, turn steering wheel from stop
to stop and measure steering angles.
●If angles are outside specification, measure rack stroke.
●If rack stroke is outside of specification, disassemble steering
gear to check rack stroke.
●Steering angles are not adjustable. If any of steering angles is different from specified value, check steer-
ing gear, the column and the front suspension components for wear or damage. If any abnormality exists,
replace the malfunctioning parts.
Removal and InstallationEGS0004F
REMOVAL
1. Remove air bag module. Refer to SRS-29, "DRIVER AIR BAG MODULE" .
2. Remove horn connector.
3. Remove steering wheel mounting nut and paint mating marks on steering wheel body and top of column
shaft.
4. Using a steering wheel puller, remove steering wheel.
INSTALLATION
Paying attention to following items, install in the reverse order of removal.
NOTE:
●When reconnecting spiral cable, fix cable with a tape so that fixing case and rotating part keep aligned.
This will omit neutral position alignment procedure during spiral cable installation.
●Neutral position (refer to figure)... Gently turn spiral cable clock-
wise until it comes to the stop. Then turn it counter clockwise
(approximately 3.0 turns) until centering mark is aligned with
adjustment mark. (Service part is fixed in neutral position with
stopper. It can be installed onto steering wheel without align-
ment once stopper is removed.)
CAUTION:
●Place steering wheel as follows: Front wheels in straight-
ahead position. R mark on the cancel claw faces down. 3
bosses align with 3 holes behind steering wheel assembly.
Check that spiral cable is placed in neutral position and that
locating pin on the left of the spiral cable is aligned with the
locating pinhole behind the steering wheel assembly.
●Do not rotate spiral cable more than necessary. Do not tighten them excessively. (The cable may
be torn off.)
●After installation, check system for proper operation by observing air bag warning lamp.
●If air bag indicator indicates any abnormal condition, use self-diagnosis function or CONSULT to
reset or cancel memory.Inner wheel Minimum : 36°
Nominal : 39°
Maximum : 40°
Outer wheel : 31°
Rack stroke : 66.5 mm (2.618 in)
