Can anyone tell me where exactly the ecu is located on a 1999 Dodge Ram Van 1500? And also how can you tell if the computer is actually no good? I have a reprogram flash and was told it is due to the engine control unit.
Answer: The PCM or ECU is bolted to the firewall just above the engine.
The only way to diagnose it is on the van by verifying voltages to
sensors and things like that. I don’t know what you mean about you have a
reprogram flash. Flashing is reprogramming of the software’s RAM only a
dealer or someone with special computer tuning software can do.
