I'm sure the answer to this applies to many models of Dodge and probably Chrysler, Jeep, and Plymouth, too.
I found the answer for newer (2001 Ram truck) vehicles but nothing I've found works on my van. The solutions I tried were:
- Press trip meter button to show trip mileage, then turn ignition on, off, on, off, on and leave it.
- Press trip meter button and hold for 10 seconds while ignition on then ignition off, on, off, on and leave it.
- Ignition on and wait, then ignition off, on, off, on and wait.
With all these solutions nothing is shown on the trip meter, no lights blink in anyway different then a normal ignition on without toggling on and off.
How do I get the P codes?
My check engine light is on (the malfunction indicator lamp/light or mil as some call it). The light remains on after starting and stays on while driving... it's always on when the ignition is on.
