Dear B.B.,

Hope you're well and stay so! It has been a while since I've been "under the dashboard". Starting from the left (closest to the driver's door) there's a rectangular, dark brown module (usually Part #9130207). This is about 3" (75mm) square. It manages the cruise control.

Moving to the right - towards the center console - there's a rack-type mounting, on which you'll find: (a) the ignition module (black, about 5" (125mm) square; (b) the ABS module (aluminum, about 3"x6"), usually with a pink label). Both of these are secured with screws.

I can't recall a post reporting ABS module failures. I'd guess they're little stressed, given mounting position (inside the cabin) and infrequency of use. That said, corrosion - that can disrupt a circuit - can occur, if a car lived in a sea-side or other high-humidity area.

Removing the driver's seat certainly eases under-dash access. Before removing the seat, be SURE to remove the negative battery cable clamp from the battery's terminal. Put the clamp into a plastic bag. This cuts power to the SRS system, the mondule for which is mounted on the floor pan, under the driver's seat.

While unlikely, a seat dropped on the SRS module could trigger the airbag. This will - at least - be very costly: the windshield is likely to be cracked and all SRS parts will have to be replaced.

After disconnecting the negative battery cable clamp, wait 10-15 minutes, to allow any SRS module capacitors to discharge.

Hope this helps.

Yours faithfully,

Spook
