To clean the ECU (Engine Control Unit) of a 1999 Dodge Ram 1500, first disconnect the battery to ensure safety. Remove the ECU from its housing, typically located under the dashboard or near the engine compartment. Use a soft brush or compressed air to gently remove dust and debris from the unit's exterior and connectors. Avoid using any liquids directly on the ECU, as this can cause damage. Reinstall the ECU and reconnect the battery once cleaning is complete.

Why would your 1999 dodge ram 1500 die while driving with no warning and then when trying to restart it all the gauges come on and the odometer say no bus?

I have a 99 Dodge Ram 1500 5.2 4x4 and it was stalling for no apparent reason, I finally gave up and changed out the ecu (the computer). If your having the same issue a quick fix is to turn your ignition off, then back on and leave it on, disconnect the wiring harness from the ecu unit, then plug them back in.(The ecu unit is on the passenger side firewall under the hood). You will see your gauges come back on. If the gauges are not on, you have to redo the process. JWFryer

The Engine Control Unit (ECU) on a 1999 GMC Suburban 1500 with a 5.7L engine is typically located under the dashboard on the driver's side, near the steering column. You may need to remove the lower dash panel to access it. Additionally, the ECU is often mounted on or near the firewall, behind the passenger side of the engine compartment. Always consult a repair manual for specific instructions and safety precautions when working with vehicle electronics.
