- You're fitting a new steering wheel to a LandCruiser 70, 76, 78 or 79 Series
- You want to know if the airbag detonator goes across to the new wheel
- You aren't sure if your truck has a steel dash or the later plastic airbag dash
Which 70 Series has an airbag to move
The dash tells you, not the engine. The plastic dash with dual airbags arrived with the September 2009 safety update. A V8 built between March 2007 and about August 2009 still has the steel dash, no airbags and the old column.
- Plastic dash with dual airbags (September 2009 on). It has a factory airbag, so the detonator moves across.
- Steel dash, metal glovebox lid, no airbags. It has no detonator, so there's nothing to move.
If your build date falls between 2007 and 2009, check which dash you have before you go any further.
If your truck has no factory airbag
On a vehicle that never had factory SRS airbags, the airbag can't be made to work. There are no airbag electronics in the steering column, no SRS clock spring and no detonator. The airbag cover on the new wheel works as a horn pad cover and you don't need to do anything to it.
If your truck has factory airbags
A vehicle with factory airbags transfers the detonator from its original airbag cover to the new one. A wheel upgrade kit for the airbag-dash 70 Series bolts straight onto the factory airbag steering hub, and you don't need a boss kit.
Leave the factory clock spring exactly where it is for the rest of the job and refit the wheel on the index marks.
Before you touch anything near the airbag
- Park with the road wheels dead straight so the clock spring is centred.
- Mark the hub-to-shaft position before anything comes off.
- Disconnect the battery and wait out the SRS discharge time in the workshop manual before touching the yellow connectors.
If the marks no longer line up when you refit, stop and have it inspected by a qualified SRS technician. Don't guess extra turns to bring it back.
The line on the new horn pad
A visible line, imprint or cutout on the horn pad is the airbag tear seam. It's the part of the cover that splits open when the airbag deploys. It's normal, it's needed, and it's on every airbag cover.
