Turn the ignition switch to LOCK (0).
Do the tilt/telescopic switch test (see POWER TILT/TELESCOPIC STEERING SWITCH TEST/REPLACEMENT ).
Is the switch OK?

YES -Go to step 7.

NO -Replace the switch (see POWER TILT/TELESCOPIC STEERING SWITCH TEST/REPLACEMENT ).
Disconnect power tilt/telescopic steering control unit connector A (16P).
