1. Do the battery terminal disconnection procedure (see page 22-68).
2. Remove the passenger’s dashboard lower cover (see page 20-102).
3. Remove the passenger’s side kick panel (see page 20-66).
4. Disconnect EPS control unit connectors A (2P), connector B (2P), connector C (2P), and connector D
(28P).
5. Remove the nuts (E) from the EPS control unit (F).
6. Remove the EPS control unit. 7. Install the EPS control unit in the reverse order of
removal.
8. Do the battery terminal reconnection procedure (see page 22-68), and do these tasks:
 Make sure the horn and turn signal switches work properly.
 Make sure the steering wheel switches work properly.
 If the EPS control unit is replaced, the EPS control unit must memorize the torque sensor neutral
position (see page 17-22).
9. After installation, start the engine, and let it idle. Turn the steering wheel from lock-to-lock several
times. Check that the EPS indicator does not come
on.
