SRS components are located in this area. Review theSRS component locations. precautions, and procedures
in the SRS section (24) before performing repairs or ser-vtce.
Remove:
LMake sure you have the anti-theft code for theradio, then wire down the frequencies for theradio's preset buttons ('99 - 00 models).
Disconnect the battery negative cable.
Remove the driver's dashboard lower cover andknee bolster (see section 20).
Disconnect the 5P connector from the under-dash
fuse/relay box and the 7P connector from the mainwire harness (see previous page).
Remove the steering column covers, then removethe mounting bolts and nuts from the steering col-umn (see section l7).
Lower the steering column assembly,
Center-punch each of the two shear bolts, then drilltheir heads off with a 5 mm (3/16 in) dritt bit.
CAUTION: Do not damago the steering lock body.
