Peake fault codes info

[shogun]

For those who are interested to buy the PEAKE I just retyped :(
as an example the data which can be retrieved from a 1991 525 E34:

Funktions:
Fc= fault code read
cE = check engine reset= clears all faults and extinguishes the the check engine light
OL= oilservice reset
in= inspection reset
Fii = only applies 12 cylinder engines DME II)
Cii = only for 12 cylinder engines, same procedure as cE

1991 525i, Chart 10, all possible faults :

1:electrical fuel pump relay, 2:idle speed actuator (close).3: fuel injector cyl. # 1, 4:fuel injector cyl. # 3, 5:fuel injector cyl. # 3, 6: fuel injector, unknown, 8: check engine lamp, OC: throttle position sensor, 10:camshaft sensor, 12: output stage, group #1, 13: output stage, group #2. 17: ignition coil, cyl. # 2, 18: ihnition coil, cyl. # 3, 19: ignition coil, cyl. # 1, 1A: control unit supply, 1d: idle speed actuator (open), 1F: fuel injector, cyl. # 5, 20: fuel injector, cyl. # 6, 21: fuel injector, cyl. # 4, 24: evaporative purge control valve, 25: oxy sensor heating relay, 29: air mass sensor, 2E: output stage, 30: A/C compressor control, 32: ignition coil, cyl. # 4, 33: ignition control, cycl. # 6, 34: ignition coil, cyl. # 5, 36: battery voltage/DME main relay, 37: ignition output stage, 3E: EML signal, 3F: torque convertor clutch lock up, 40: ignition timing intervention, 43: crankshaft sensor, 46: oxy sensor, 49: veficle speed signal not present, 4C: idle CO ptentiometer, 4d: intake air tempareture, 4E: coolant temperature sensor, 51: DWA input, 52: engine drag torque control (MSR), 53: intervention, ASC, 55: A/C compressor, 64: output stage, C8: DME control unit, C9: lambda control, CA: fault code memory error, Cb: ignition circuit primary monitor, CC: stall protection.
----------------
How to use:
1) turn on key (DO NOT START ENGINE)
2) plug tool into diagnostic connector-tool is ready to use when it displays "FC".
3) use the "Select" button to select one of the functions.


A Note To NON-U.S. BMWS:
The above vehicle reference refers to US specification BMWs only, and does not include any non-US BMW variants. To best use the R5/FCX on your non-US-BMW, you will need to determine which of the above most closely matches your BMW. For instance a 1991 320i, is a e series, four cylinder, made for non-US markets: In this case the best chart for you to use would be chart 13, as the closest US spec car would be a 1991 318i (which alsois a 4 cylinder 3 series). This method does not always work, you may need to expermiment to find the correct chart.

There are additional optional adapters for newer BMW models, airbag light resetting etc.

Cars built earlier - like my 1988 750 - can get less fault codes, somthing around 20 in total.

This just for info in case you are intending to buy a tester.
I am recommending it.
Very handy, small, needs no battery, fits in glovebox compartment.

Awsome...so it looks like I can use this on both my e34 and my moms 00' 740i. Perfect.

[brodee]

I've had 2 of these and they have worked on 5 of the 6 BMW's I've had. The only one it didn't work on was my '87 325e since it had the earlier diagnostics port.

Definately worth the money. I take it to shows with me and run codes for friends and anyone else.

[Guapo]

Agreed. It was one of the first purchases I made after I bought my E34.

I also made a small laminated business sized card that fits in the Peake case that has the fault codes listed on it, so I don't need to refer to the Peake manual.

Shogun,

I bought a peake diagnostic tool which worked for the first few weeks in May 2005. In the last 6 months however, I get an error ("E") flashing each time I try to download fault codes from my DME ver. 3.3. I understand this means no communication between the ECU and the Diagnostic Port. I have tried all the hints from the tool manual without joy.

Any ideas on how to resolve? My tool is okay as I have used it recently to decode faults other Bimmers in my locality.

Regards
Isah.

Some weeks ago I had a similar case on my car, car was even running in limp mode = max. 1.500 RPM.
Turned out that 2 wires in the main engine harness connector (next to the diagnosis box) were lose from underneath. It could be that this is similar on your car. But as your engine is running, it could be a cable which goes into the diagnosis box.
Javier just posted these pins and where they go. Maybe you check that one out. Scroll down in this link

Thanks hugely, Shogun. Will check cables going into the Diagnostics Port. I hve noticed the Port moved freely each time I try to remove the cover.

Josh, I know it will work on your mom's 740, you will need an adapter if the OBD port is under the dash on the left hand side of the steering column. They changed the location from under the hood to under the dash sometime in 2000 or 2001, and I can't remember which year. The new under dash port is a 16 pin and the adapter works great. I use one on Lori's '01 525.

"Thanks hugely, Shogun. Will check cables going into the Diagnostics Port. I hve noticed the Port moved freely each time I try to remove the cover"

Shogun,

Checked and all cable connections look okay from the diagnostics port to the tranny computer or DME? The flashing "E" still persists. I wonder if it could be one of the switches or fuses downstream?

[shogun]

Hmmh,
just checked the manual, it says:
tool must be fully inserted in order to work properly. To check the full insertion, first observe the faint kine on the side of the connector on the R5/FCX. That line should be just even with the top of diagnostic box connector. If that line is more than 1/16th of an inch above the top of the diagnostic connector, the tool is not fully inserted.
--------------------------------------------
Going back to lose cables: I also did not see anything wrong, but only found out by measuring all pins.

Edit:
check for good and clean connections. You live in Nigeria, probably quite humid there. Try a good non-flammable electric/electronic contact spray for all connections, which sometimes helps a lot.

Thanks for your patience with me, Shogun. I have checked the insertion and sprayed a good electronic contact cleaner - still no joy! What I didn't do,however, was to "measure the pins" - how did you do that? Do you mean check for continuity?

Does this tool read any codes even when the check engine light is not lit? I am considering this purchase, after having used the SRS reader to fix my airbag problem this weekend.
