SYS light,,

[Toyvet1]

I am getting a SYS blinking three times and the range goes to 0. The speedo doesnt work and no SES light. How do I draw the codes out, I tried the grounding the a and g terminals with no luck.

Tomorrows project will be clean the terminals below the battery...any ideas

Okay, usually....and I stress usually that symptom is a bad battery. It goes along also with your other thread.

How old is the battery? Our cars are electric hogs because of the old er electronics. Not as power use efficient as the newer stuff on today's cars.

If the battery resting state voltage is below 12v, the "sys" light will flash when you try to start the car. Also, if the battery is too far into the 11v range the LCD does all kinds of strange things. Check the voltage as it's proly below the 12v mark.

Will no SES light, it could be the PROM ECM or burnt bulb.. I have an ECM you could check to see if SES works,

TomTom I replaced the battery when I had the battery drain problem this spring. Today it getting a good bench charge and will check it this evening when I get home.

Jeff Im getting SES with key on engine not running. Just no ses light when car is running. I was told ecm must be getting a signal for the vss if no ses light. CCM sends speedo , cruise and radio the vss signal.

Ill check battery tonight and clean conections like Pizza Bob suggested...

Ken,

Does SES light blink once when you first turn key to ON, not start? If it does, that's the ECM checking OK.

Guys he's getting SYS not SES.
SYS is usually a low or bad Battery.

I've had the same problem, bet your climate control doesn't work either. For some reason when the battery goes low, it blows the A/C fuse and you will be unable to pull any codes. There's a one liner in the FSM about not being able to pull the codes with that particular fuse blown. Charge up the battery, replace the fuse and I'll bet all will be good again.

Didnt have time to do much tonight. Charged the battery all day and was at 12.8v . Started the car and same problem. I did notice the ses light did not come on when key on engine off. Saturday I check the bulb and go from there.

Did check all the fuses and they were good.

We are all having gremlins in Illinois, I am getting my ASR and ABS lights coming on but no codes.

Lee,

When you "Key On", are you getting the SES blink once?
Are you currently running a chip piggybacked on stock chip using adapter.
I found out that my problem Sunday at Haibeck's was BOTH the stock chip and my Ostrich. I re-burned the chip and now it's running fine. Still trying to eliminate adapter from the issue.
I think Ostrich may be DOA although it uploads and downloads fine.
