Help on brake Codes
Question:
Does anyone have a reference for brake codes on a 89 Gmc truck. I recieve the following codes from the flashing brake light on my console, 9 flashes then 1 stays on for about a second, and repeats. Any ideas… Thnks Ron
Response:
Code 9= open/short in speed signal circuit to ECU,intermittent speed signal voltage to ECU,faulty instrument cluster. Before you buy.
Response:
This page has some info: http://www.autosite.com/garage/encyclop/ency14l.asp For code 9 it says you’re supposed to read the voltage at some terminal, but you need the service manual info to interpret the results. — Robert Hancock Saskatoon, SK, Canada Home Page: http://members.home.net/hancockr
