1998 Dodge Ram Truck Cummins diesel ECM
1998 Ram Truck, Cummins diesel. Second-generation Ram. Magnum 5.2/5.9/8.0 V10 gas and 5.9 Cummins 12-valve / 24-valve diesels. OBD-II is in force. Diesel listings that say firewall sit up on the cowl. On the 1998 Dodge Ram Truck the ECM usually sits engine bay; second-gen diesel trucks often used a firewall-mounted controller, later trucks move it to the driver fender or beside the master cylinder.
On a 1998 Cummins Ram the injection is often still VP44. Check the door-jamb build date if you are on the 2002–2003 edge.
What we hear on these diesels
- crank-no-start after the truck sat in the rain with a leaking cowl
- odometer / cluster antics plus a stored P0601 or internal-control code
- dead pedal in a work zone — throttle goes to zero
- Cummins that white-smokes and will not build rail pressure
- no-comm on the CAN bus after a jump from a welder or charger
We program it to your VIN before it ships, including the immobilizer so the keys you already have are the ones the car expects. Lifetime warranty. Ground shipping is $14.95.
