"Service ASR" & 'Service ABS" lights
My Z has started a strange habit of turning on the "Service ASR" & "Service ABS" lights on every so often. Its only while I am out driving it and it isn't every time. Upon initial start up the lights go through their normal check and then stay off until something goes funky and the come on.
Turn the car off and after restarting the lights are off. They don't always come on and havent been able to reproduce them coming on under controlled circumstances. Is this an indicator something is about to go out? I have a Genisys scan tool but honestly doesn't read the OBD 1 cars that well. need to save up for a Tech1. Have not pulled any codes as I haven't had the scan tool connected when the lights have come on. Anyone experience something similar? thanks |

Re: "Service ASR" & 'Service ABS" lights
yeah I looked at that too. I recently flushed all the lines when I put on the GS calipers, new pads & rotors. So the master cylinder is full.
And this just popped up, I had a few hundred miles on the new brake set up before the lights started coming on. unless I somehow have an air bubble that was hiding in the system that found its way to the abs controller.... that's why i find it slightly odd. |

Thats entirely possible (Air in the system) I suggest a good bled of the system again to just rule that out. Ive done your exact brake setup on my car and nary a problem.

Re: "Service ASR" & 'Service ABS" lights
Have you moved the Spark Plug Wires recently?
If they're mis-routed, they can emit EMI - same as a nuke, and solid state sensors and nukes don't get along. (me either - I'm fresh out of SPF nuclear strength)

Re: "Service ASR" & 'Service ABS" lights
these are all good tips. thx
I have not moved the spark plug wires recently. I did change the plugs but didn't put new wires on. and it appears all the OEM wire looms, etc are still in place. I will tinker with it this weekend and see if I can consistently recreate the problem. |

Re: "Service ASR" & 'Service ABS" lights
If the Service ASR and ABS lights are coming on, codes are stored in the EBTCM.
Your scanner will not read them so you need to look at this article to see how to get them. "Pull" the codes and report back.

Re: "Service ASR" & 'Service ABS" lights
Thanks everyone.
Hib - will read your article and report back. its strange to me that it is only under hard braking where the body pitches forward. still think i have air stuck somewhere in the system. the MC is full and clear. |

Re: "Service ASR" & 'Service ABS" lights
My gut feeling is what's turning those lights on is unrelated to brake hydraulics.
I'd get the codes then diagnose per the Service Manual. I'm going to guess there's a wires/connections problem somewhere. |

Re: "Service ASR" & 'Service ABS" lights
Ok. Finally got back and looked at the trouble codes. 77 ignition cycles ago it threw a code 71. 2 ignition cycles ago it threw a code 83.
71 is an internal malfunction of the EBTCM 83 is low brake fluid. My m/c is 1/2 way full. Will top it off. The code 71 is obviously much more of a concern. I will say the lights only come on during heavy braking or acceleration as I believe the body movement uncovers the fluid sensor in the m/c. Hopefully topping off the m/c will take care of it. .. Cleared all the codes. I am using a Tech 1a for reading them. How did I ever survive without one!? Definitely a "must have" item for diagnosis. Any additional advice/thoughts? |
