Turn the ignition switch to ON (II) and check that the SRS indicator should came on for about 6 seconds and then go off.
Make sure the horn and turn signal switches work properly.
Make sure the steering wheel switches work properly.
After installation, do these checks:
Start the engine, allow it to idle, and turn the steering wheel from lock-to-lock several times.
Check that the EPS indicator does not come on.
Check the steering wheel spoke angle. If steering spoke angles to the right and left are not equal (steering wheel and rack are not centered), correct the engagement of the joint/pinion shaft serrations, then adjust the front toe by turning the tie-rod ends, if necessary.
