'check engine' light bulb not working. Whats required to fix.
During routine smog check the inspector said the emmision passed but the check engine light is not working. This is a 1997 2500 ram conversion van with a 390 c.i. V6 automatic. Is there easy access to this bulb?

The smog check requires a visual inspection of your check engine light. It has to come on for a bulb check at startup to make sure it's working. But, the light must go out after starting the engine(it cannot stay on after the engine starts during a smog check). If the check engine light fails either of these two tests, the vehicle will fail the smog check inspection. You need to have the cause of your inoperative check engine light diagnosed and repaired.
No this is not right. If you remove the battery everything resets anyways. If they are talking about relearn procedure, it should only require 50 miles. But if the light is on than either they did something wrong, created another problem, or there was already another one existing. Have the code read and let me know what it is. I'm in Ca too and used to prep european cars for smog, so I do know what I'm looking for. How did the rest do? What were the readings(if possible)?
this should not effect your emmisions test.however if you recently changed your oil.there is a reset switch under the hood in the fuse panel unless you've changed the oil recently don't reset it .hope this helps
