Using the paper clip trick to get to diagnostic mode.
I only got on code "H63". I know the H stands for "History" (old) but what's the 36 for? It was in Module 9 if that's important. My "Service ASR" light, "Service ABS" light, and "ABS Active" light are all lit right now (have been since I've bought the car). I know the ABS and ASR are tied into each other in a way but does my code have anything to do with the traction control? |

It's an "opti" code.

Hmm Well for one, what's that mean lol and two, I don't think I've had any trouble with that
I figured if the lights were on, there would be a code to go with it. Where are my codes!? lol My dad said he might have an OBDI scanner so I'm going to try that also tomorrow. |

I dont have a service manual for a 92, so im not sure what that code is yet. If its in module 9 its got nothing to do with the distributor i know that much. ABS/ASR is the antilock brakes and traction control. |

Burn the Chilton's manual. or use it for a wheel chock. The FSM will decipher the codes, and it provides a trouble shooting chart for locating the cause of the codes.

Or check this: C4 Guru - 1992/93: Reading CCM Codes
The H63 means "Valve Solenoid Circuit Error." Whatever that means. |

One question I had was I know the H means it's an "old" code. I was pretty sure I cleared it, drove around the block, and when I tried it again, it still showed up as an old code.

"old" code is nebulous at best. Basically, it is a "stored" code. The only way you can get a C code is if you are watching it happen with a scan tool.
I will dig out my helm and check that code. Gimmie a bit, I have to run some errands. |

CFI-EFI say everything best no matter how he says it. The man is very rarely incorrect, and this instance is no different. From what the code is, DTC 63 in module 9, which is as Bogus stated above, your going to require the REAL manual, which you can get from the link posted be CFI-EFI above, in order to have exactly what you need right there infront of you when you need it. Clear those DTCs using the method here: http://www.c4guru.com/articles/CCMCodePull.pdf (page 11 i believe) and see what occurs. Check all the connections and have a bit of a play with the wiring and then start'er up and go for a drive, see if it all works or same DTC. |

On the 92, almost everything will show up as an "H" except tha C12 (no codes). I think this happens when you shut off the key and any codes get stored.
In module 9, the H63 is Valve Solenoid Relay Fault ( Valve Solenoid Circuit Error on Andy's sheet, same thing). Yep, looks like that will trigger the ASR/ABS lites. When the ign is on, this realy provides voltage to activete the solenoids and provides a ground path for the "service abs" lamp. Service ABS and service ASR lites will be on and a code 63 will be set when the Valve Solenoid relay voltage falls to less that 5 volts. I'd first try and reset that code, go to 9.7 to reset, and see if it comes back and the lites go out. If not, BURN the Chilton. The diagnosis is on page 5E1-82 in the real manual. BTW, I want your wheels for my Black Rose. |

Like I said, I'm pretty sure I deleted the code the first time around, and the lights never went off. When I did the check again, the code either came back or was still there. Where is this Valve Solenoid at if I need to change it? |

I put my manuals back down in the shop and am feeling lazy right now. I'll try and check in the morning, it takea a while to find this chit in the manuals sometimes, the location isn't shown on the diagnosis page. But, Im betting it's behind the driver's seat in the ABS compartment. |

Yep, youve gotta do all that, and id have to say, if the codes were cleared, when the vehicle is started the MIL lamps should all go out, including the ABS and ASR lamps until you reach the 3mph test, if they are not going out, id say youve got some sort of a short to ground in there, or other electrical issue.

Couple of things: 1) I'm aware of the fact that there are a number of things that could cause the code to be thrown, but if I know where to look for the "valve solenoid" then I could maybe trace down a faulty wire or bad ground somewhere. 2) Maybe I'm not erasing the code the right way. I'm pretty sure I went to 9.7, got it to show three dashes, but then I turned the car off and pulled the paperclip out. Should I start the car after getting the dashes? Or what do you mean but "other electrical issue"? |

1: Its behind the driver seat in the rear compartment.
2: Just unplug the battery and leave it that way for a while, then come back, reconnect and test. The MILs should all light up on start up to show they are working, and they should then go out after 2-3 seconds. 3: If any of the MILs light up and dont go out when they vehicle is tunred on, youve got some sort of issue that the CCM can see wrong with module 9 before the car gets to the 3mph speed for the ABS self test. It should only be able to see wiring faults and/or comunication issues until the selftest. 4: Consider load testing the battery. |

You should see C-12 first, then it will cycle thru 1.0, 4.0 and 9.0, and should show 3 dashes at each one. I don't think starting the car is necessary for this particular problem. Unhooking the battery probably won't change anything but it's worth a shot. |

It does on mine, C12 shows there is no DTCs present in the CCM module (module 1). The other modules are only displayed through the CCM (module 4 being ECM, module 9 being ASR/ABS, and module A being air bag). |

I got a friend that printed me out a few sheets on the code from something called "Alldata"? He works at a repair shop so I'm assuming that's what they use. It has a step by step check thing too so I'm going to try to give that a go when I get a chance, hopefully tomorrow.

AllData is a "Chiltons" or "Haynes" type of service that shops subscribe to from Auto Zone. I haven't seen any of their trouble shooting charts, but just knowing the source makes me leery. Have you ever found an Auto Zone parts person that knew what they were talking about? I can see the economy for a shop. It would be impossible to keep a FSM for everything that might roll in off of the street. But for a hobbyist with only a couple of vehicles to be concerned with, why trust a second hand source of info?
