How to Complete Dodge Ram Van Drive Cycle - Following the driving instructions below will allow your Dodge Ram Van to complete the emission monitors required to pass the smog inspection. Emission monitors (I/M readiness flags) are internal self tests which the ECU (engine control unit) performs to ensure all emission systems are functioning properly. Typically driving for a few hundred miles over the course of a week, in both highway and city conditions, is enough to set the emission monitors. However, due to different driving habits, the criteria required to run a monitor may not always be met; and a Dodge Ram Van drive cycle must be performed.
The drive cycle pattern below should make READY/COMPLETE the emission monitors needed to get van to pass the smog check. Follow the drive cycle carefully. Take extra caution when performing the drive cycle on public roadways. If you feel you will be unable to follow the Dodge Ram Van drive cycle safely, please seek assistance from an smog check repair station or Dodge dealership. They may be able to perform the drive cycle utilizing a dynamometer, and specialized scan tools. Prior to beginning the drive cycle ensure your Dodge van has between 15% to 85% fuel in the gas tank, and that the engine is cold; after a cold soak (basically this means starting the driving pattern in the morning).
All Monitor Drive Cycle - This drive trace is intended to make READY all the emission monitors listed below in one drive cycle. It is recommend to perform the driving pattern below at least two times. Due to the limited preconditions provided with this All Monitor Drive Trace, it is recommended to use the monitor specific drive traces for Dodge and Chrysler vehicles. Try the ALL Monitor drive cycle at least twice. If all monitors are not complete, complete individual monitors.
Pre-Conditioning Requirements
MIL (malfunction indicator lamp) must be off - Cold start (Best to start in the morning after the van has sat overnight)
Driving Procedure
1) Start and warm engine up for five minutes.
2) Drive, keeping a steady throttle, at a speeds between 40 and 60 mph for 8 minutes.
3) Stop and idle for 3 minutes.
4) Drive, keeping a steady throttle at speeds between 20 and 30 mph for 2 minutes.
5) Stop, turn key off and leave off for ten minutes. This will allow the O2 sensor heater monitor to run.
Catalyst Monitor Drive Cycle
Pre-Conditioning Requirements
MIL (malfunction indicator lamp) must be off. - No DTCs (diagnostic trouble codes) present. - Fuel level is between 15% and 85% full. - ECT (engine coolant temperature) above 70º F. - Engine must have been running for at least 90 seconds, and engine must be between 1,350 and 1,900 rpm during this driving pattern.
Driving Procedure
1) Idle your van for five minutes.
2) Drive with a steady speed between 30 and 45 mph for 2 minutes.
EGR System Monitor Drive Cycle - Vacuum Controlled
Pre-Conditioning Requirements
MIL must be off.
Driving Procedure
1) Idle your van for five minutes (to reach closed loop operation).
2) Drive with a steady speed between 40 & 60 mph for 8 minutes.
EGR System Monitor Drive Cycle - Electronic
Pre-Conditioning Requirements
MIL must be off. - Engine speed between 500-850 rpm. - ECT is above 180º F. - No misfire temporary or matured fault present. - A/C system and cooling fans must be either on or off, but can not change state.
Driving Procedure
1) Idle your van for five (5) minutes.
2) Drive with a steady vehicle speed between 40 & 60 mph for 2 minutes.
3) Idle your van for three (3) minutes.
Note: This monitor evaluates EGR flow based on a change of engine roughness (idle stability). Conditions causing un-stable idle will prevent this monitor from running.
