These are pictures of the 964 steering wheel, very similar to the 928 Airbag steering wheel.
Another DIY: Replacing your turn signal
assembly
--------------------------------------------------------------------------------
For some time now, my left turn signal has not automatically cancelled.
I decided to combine a replacement of the turn signal assembly with a change to
a new steering wheel (photos of that to come).
There a number of different turn signal assemblies available, depending on
options installed on the car (cruise, computer, etc). I purchased p/n
964.613.335.00 for my car (cruise/headlight washer/no computer) from
www.automotion.com .
Total time (including pictures and some confusion) for the swap was about 2
hours. I used Joey's excellent DIY as a starting point.
Step 1
--------------------------------------------------------------------------------
Disconnect the battery and wait a minimum of 20 minutes to be able to safely
remove the airbag.
Using a T-30 screwdriver, undo the two Torx screws behind both sides of the
steering wheel to remove the airbag.
The airbag the can be lifted out. Unplug the connector and safely store the
airbag facing upwards out of the reach of children and/or driver's of Honda's
with coffee-can exhaust systems.
Turn the steering wheel to centre the wheels and mark TDC using a permanent
marker on the end of the steering shaft.
Then undo the centre nut (pointed out in red below) using a 15/16" socket with
an extension. Remove the nut and washer then lift the steering wheel off of the
steering shaft.
Step 2
Pictured is the steering shaft and column
with the horn contact ring. The wire with the red plug is for the airbag.
The next step is to remove the plastic surround around the column. This requires
removing the 4 screws on the front (red arrows) and the 2 smaller screws (one on
each side - blue arrows).
Step 3
--------------------------------------------------------------------------------
With the screws removed, gently lift the upper surround off then wrestle the
lower one off. The lower one is tricky, especially around the cruise control
arm. It takes a little wrangling but it can be done - it was made easier by
pulling the cruise control stalk forwards slightly.
Step 4
--------------------------------------------------------------------------------
Pictured is the steering column with the plastic surround removed. Visible
better now is the horn contact ring and, behind that, the turn signal assembly.
Step 5
--------------------------------------------------------------------------------
Mark TDC on the white plastic ring of the horn contact ring using a permanent
marker.
To remove the horn contact ring, undo the two screws holding it in place (red
arrows) and then gently pry it forwards off the splines of the steering shaft
which it is press-fit around. Take your time doing this and use a wide
screwdriver - mine was very tight and I imagine it is very easy to snap this
piece.
Step 6
--------------------------------------------------------------------------------
Gently pull the wire from the bottom of the turn signal assembly forwards from
under the dash and unplug the keyed connector.
Step 7
--------------------------------------------------------------------------------
Here is the back of the horn contact ring - the catch to cancel a turn signal
can be seen. Mine was not broken or damaged which might have been a reason for
the turn signal to not cancel automatically.
Step 8
--------------------------------------------------------------------------------
The wires for the horn contact ring do not have to be disconnected
Step 9
--------------------------------------------------------------------------------
This just leaves the turn signal assembly.
Flipping the turn signal makes a small lever flip out near the steering shaft
and the catch on the back of the horn contact ring is supposed to flip it back
to cancel the signal. On mine, it would properly release turning right but would
stick when turning left -- hence, the problem I am trying to fix.
It might be possible to fix this but, since it is a sealed box that is riveted
together, I decided to just replace it -- I'll take it apart some day and post
pictures of the innards.
Step 10
--------------------------------------------------------------------------------
Using an 8 mm socket, loosen the bolt on the bottom of the turn signal assembly
that holds the assembly to the steering column. Unplug the two large keyed plugs
on the back of the turn signal assembly and pull it forwards and off the column.
Step 10
--------------------------------------------------------------------------------
Using an 8 mm socket, loosen the bolt on the bottom of the turn signal assembly
that holds the assembly to the steering column. Unplug the two large keyed plugs
on the back of the turn signal assembly and pull it forwards and off the column.
Step 12
--------------------------------------------------------------------------------
Here are views of the front and back of the turn signal assembly.
Step 13
--------------------------------------------------------------------------------
Re-installation is just the reverse of the above.
Slide the new turn signal assembly onto the steering column and plug the large
keyed plugs into the back of it. Position the assembly on the column leveled and
tighten the bolt on the bottom using the 8 mm socket - I could not find a torque
value for this so I just made sure it was tight.
Plug the wire from the assembly into the dash plug again and push the wires back
into the dashboard.
Put the horn contact ring back on, rotated so the mark for TDC is oriented
correctly (this makes sure the catch to cancel the turn signal assembly in the
right place). Secure the horn contact ring back in place using the two screws.
At this point, I made sure the new assembly worked by turning the key to the
first position to undo the steering lock and slipped the steering wheel back on.
I tried the turn signal for both left and right turns to make sure turning the
wheel cancelled it properly - it did.
Wrestle the lower plastic surround back on to the bottom and then top and secure
using the 6 screws (4 on the front, 2 on the sides).
Put the steering wheel back on with the washer and nut. Tighten to 33 ft.lb. DO
NOT tighten the bolt by pushing against the steering lock - hold the steering
wheel and tighten.
Lift the airbag back into place and plug it in. Secure the airbag using the T-30
torx bolts on the back of the steering wheel again.
Reconnect the battery and check for the airbag warning light - there should not
be one but if there is, you will need 5 minutes with a Bosch Hammer or a trip to
the dealer to get cancelled.
