Hi everybody.
I have been looking usin forum search egine, but could not find anything... is there a way to get error codes from ecu to dashboard display?
In my old Chevrolet Corsa Classic (Opel Corsa C), if you jumped ODB conectors 1 and 2, ecu displayed error codes to dashboard display, without a Scanner.
It is possible in my Aveo LT 2010 1.6?
OBD1 you could usually get the codes by a flashing engine light. With OBD2 you need a scan tool.
yeah, the cheapest route is to buy a cheap obd2 wire of ebay that comes with some cheap software that will gread you the codes, works well for $15, and other more advanced programs can be used with the same wire also
ok, an OBDII ELM 327 scanner tool will work?
How to get the ABS (chassis) DTC's on Chev Aveo using ELM327 based interface:
I found that the ABS CPU (address 28 ) doesn't always respond and the line
sometimes need to be re-initialized.

This is what the request and response message translates to:
>134000 //Mode $13—Request Diagnostic Trouble Code Information in group 40 (chassis)
8E F1 28 53 //the header
06 //there are 6 trouble codes
C1209 //Right Rear Wheel Speed Sensor Circuit Open or Shorted
C1206 //Left Rear Wheel Speed Sensor Circuit Open or Shorted
C1203 //Right Front Wheel Speed Sensor Circuit Open or Shorted
C1204 //Right Front Wheel Speed Excessive Variation
C2402 //Pump Motor Failure
C2112 //Valve Relay or Fuse Failure
37 //Checksum
Check out the ELM327 datasheet on page 31 to see how to interpret the trouble codes.
Also check out SAE J2190 on how to use mode $13 (and mode $14 if you want to clear the DTC's).
Hi Aveo.ELM
I have done as you did here with an ELM327 using the software called OBD 2007
