Abs tcs light

[stcspiderman]

anyone know what is tripping these codes c0236 c0896 c0550

My abs and tcs light come on when driving, then my steering gets harder

I can park the car go out next morning or later in day light will be off after driving for a little bit comes back on.

Was wondering anyone has had same simler problem.



One thing I did was this plug I put one in from Pontiac grand prix 3100 engine there different My volt went crazy talking 15.7V or more little box shows car doors went blank then came back on. I only got abs tcs light after install of alt plug from 3100 engine. I have right one now.

I did a search found this write up on Stuff in bold

Could Of I damaged the ebcm? I would I know If I did?

DTC C0896: DEVICE VOLTAGE RANGE/PERFORMANCE
Circuit Description
EBCM is required to operate within a specified range of
voltage to function properly. During ABS and TCS operation, there are
current requirements that will cause voltage to drop. Because of this,
voltage is monitored out of ABS/TCS control to indicate a good
charging system condition, and also during ABS/TCS control when
voltage may drop significantly. PCM also monitors for high voltage
conditions which could damage EBCM.
DTC sets when EBCM operating voltage at terminal No. 8 (Pink
wire) drops to less than 9.4 volts out of ABS/TCS control, or 8.8
volts during ABS/TCS control, or EBCM operating voltage at terminal
No. 8 increases to greater than 17.4 volts. Condition must exist for
more than 500 milliseconds with vehicle speed above 3.6 MPH.

Sounds like your EBCM fried... ours are apparently notorious for taking more juice than they can handle - rebuilders solder in parts to keep this from happening. Do a search and you'll find plenty of info here from the past couple months.

As for your wiring... if your battery voltage is surging, you've got another problem entirely aside from your EBCM.
