Jimny diagnostics

This page really is about a holding area for sub-level topics as I’m increasingly seeing people needing help diagnosing things like wiring issues or blown fuses/circuits not working.

  • Onboard diagnostics info
    Everything you need to know about using onboard diagnostics for the Jimny; I will also attempt to catalogue diagnostic error codes although it’s quite a large task so might never be fully complete.
  • Wiring
    Where I’ll collect as much info on wiring and connectors as I can
  • Fuses and what they protect
    Complicated enough wiring that this is a useful thing to consolidate!
  • 4wd system
    Got an issue with the car’s 4wd system? Here’s a place to investigate it. Somewhat under development but trying to consolidate wiring, module, physical and vacuum system diagnostics all in one place.
  • Death wobble
    Is your car wobbling at speed? Here’s an article to go through some of the things to check, and some common issues that might cause this.
  • Cooling system
    Information on the cooling system and info to help diagnose cooling system issues
  • Case studies
    • Autonomous braking service warning: example 1
      SERVICE WARNING appeared on dashboard after every key on; entire dashboard orange and unable to be reset
    • Autonomous braking service warning: example 2
      SERVICE WARNING appeared on dashboard when braking; reset every time car was started and did not reoccur until some braking event of sufficient force.
    • Unstable at speed
      Owner described feeling like the car was horrifically unstable at highway speeds after a lift was installed. Caster correction was installed as part of the lift installation.
