How to Set I/M Set for Chrysler Vehicles

This article show a guide on how to perform the I/M Set Procedures for Chrysler vehicle.For 1996 Chrysler vehicles do not maintain readiness after engine shutdown. The vehicles can be re-programmed to fix this problem, and may already have had a re-programming that addressed this issue. And for more about Chrysler,check here:Chrysler Repair Projects

 

All Monitor Drive Trace

Pre-Conditioning Requirements:

– MIL must be off

– Cold start (Note: cold start temperature is undefined)

Driving Procedure

1) Warm engine up for five minutes (must reach closed loop)

2) Drive (with steady throttle) at a speed between 40 and 60 mph for 8 minutes.

3) Stop and idle for 3 minutes.

4) Drive (with steady throttle) at a speed above 20 mph for 2 minutes.

5) Turn key off, leave off for ten minutes (to run O2 sensor heater monitor).

Note: Due to the limited preconditions provided with this drive trace, NCVECS recommends using the monitor specific drive traces for Chrysler vehicles.

 

Catalyst Monitor Drive Trace

Pre-Conditioning Requirements:

– MIL must be off.

– No DTCs present.

– Fuel level is between 15% and 85% full.

– ECT above 70º F.

– Engine must have run at least 90 seconds

– Engine between 1,350 & 1,900 rpm.

 

Procedure

1) Idle vehicle for five minutes (to reach closed loop operation).

2) Drive with a steady vehicle speed between 30 and 45 mph for 2 minutes.

EGR System Monitor Drive Trace – Vacuum controlled

Pre-Conditioning Requirements:

– MIL must be off.

 

Driving Procedure

1) Idle vehicle for five minutes (to reach closed loop operation).

2) Drive with a steady vehicle speed between 40 & 60 mph for 8 minutes.

EGR System Monitor Drive Trace – Electronic

Pre-Conditioning Requirements:

– MIL must be off.

– MAP must be between 0-60 KPa.

– Engine speed between 500-850 rpm.

– ECT is above 180º F (90º C).

– No misfire temporary (pending) or matured fault present.

– A/C clutch, PS Switch and Cooling fans do not change state (turn off).

 

Driving Procedure

1) Idle vehicle for five (5) minutes (to reach closed loop operation).

2) Drive with a steady vehicle speed between 40 & 60 mph for 2 minutes.

3) Idle vehicle 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.

 

Evaporative System Monitor Drive Trace

Trace 1: Standard Type

Pre-Conditioning Requirements:

– MIL must be off.

– No Evaporative DTCs present.

– Fuel level is between ½ and full.

(Note: monitor may still run with tank fill between 15% and 85%).

Driving Procedure

1) Idle vehicle for five minutes (to reach closed loop operation).

2) Drive with a steady vehicle speed between 30 and 45 mph for 2 minutes.

Trace 2: Leak Detection Pump

Pre-Conditioning Requirements:

– MIL must be off.

– No Evaporative DTCs present.

– Fuel level is between 30 & 85 % full.

Driving Procedure

1) Cold soak vehicle, start and idle vehicle for 4 minutes.

2) Drive in-town (stop and go) for 5 minutes, using smooth accelerations and decelerations.

3) Stop and idle vehicle for 4 minutes.

 

O2 Sensor Monitor Drive Trace

Pre-Conditioning Requirements:

– MIL must be off.

Driving Procedure

1) Idle vehicle for five minutes (to reach closed loop operation).

2) Drive with a steady vehicle speed above 25 mph for 2 minutes.

3) Stop and idle for 30 seconds.

Pre-Conditioning Requirements:

– MIL must be off.

Driving Procedure

1) Idle vehicle for five minutes (to reach closed loop operation).

2) Shut engine off and leave vehicle off for ten minutes.
