SST for checking codes

Post by **clawnz** » Fri May 27, 2016 1:38 pm

Am I right in thinking SST = Special Service Tool.
Can someone tell me if this tool for checking diagnostic codes, is just a light bulb and two leads and probes.
It has to flash the codes, so assume it is a light bulb, but just checking before I do anything.
As shown on page SR-56 of the BGB.

The SST (yes Special Service Tool) for this is just a metal clip. Use a wire or paper clip in place of the SST.

We all do it.

For this it looks as though the red P/S light on the dashboard is the flashing light you will be looking for.

Thank You.
God I am dumb, It says on that page note the number of times the P/S light blinks.

I use a set of tweezers with a very fine point. Works well. But yeah a paperclip does the job too...

It's all good. I didn't even know the P/S light could blink as part of the diagnostic system. I thought only the orange CEL (Check Engine Light) would flash when doing any sort of wire jumping with the SST on the diagnostics box. Thanks to you I now know just a little bit more about these cars.

Next!
Ok so I have a BGB but not for Gen3.
According to what I make it, I am looking for what a code 13 means. could it be the same as 12 in the BGB I have?
And in the BGB I have there is no code 13.

Just reading this and it appears the code is for 'Abnormally High Voltage to Power Steering Pump'
http://www.imoc.co.uk/forums/viewtopic.php?p=1495153

However I don't have proof this is true. Maybe something is up with the pump causing more resistance to turn it on when cold. Maybe new fluid or another pump would fix this issue. Half the problem with any of these fixes is the cost and messing around trying to replace the parts. I'm sure someone else can say how hard or annoying this would be.

Have you checked what the battery voltage is when the car is running? An alternator that is overcharging is also possible.

Again thank you for your input.
I am moving towards 'Pump' It does make more noise than I have heard any other pump.
When it is working that is.
I am lucky in that I have good working spares and thinking change out pump and rack, while under there.

Just be aware that most stuff after November 1993 has different part numbers to stuff before that. I'm not sure if this will cause you issues but it's just something to be aware off.

A very valid point. I have to wonder if that is a double blind though.
Remember I have already plugged up both ECU's and relay. From a 1992 and no noticeable concerns. All responses were the same.
I am almost certain the pumps are the same. Don't know about the rack. But no sensors on that anyway, so change out pump and rack should (I hope) work.
Tomorrow I will drain the system and replace the oil. Nothing the loose doing that.
I am wondering if Jim could be right and a valve in the rack is giving trouble. Not sure there is any control valves in the pump.
Could a sticking valve put pressure on the pump motor causing the ECU to drop it out and throw the 13 code.

14.6volts this morning. On cold start up.
No pump running.
it's raining yet again so plans to drain and refill are on hold.
But did run up pump from the 92 and it runs almost silent. When I get the 96 pump to run I will try to record the noise it is making.
Sounds very suspect to me.
Thinking a bad pump could be drawing high current. Could the ECU reading that as high voltage!
