I just replaced my systems monitor. Now I am getting boxes across the screen.
This readout isn't listed on the troubleshooting guide.
Help please...
I've replaced my systems monitor on the dash. Now I'm getting a data link failure alarm. I need to replace the coax but can't find the interface module. The only thing in the engine room is this photo on my firewall. Its not behind the electric panels downstairs.
What is this and where do I...
