If Module is Slow to Calibrate

One or more of the following conditions may increase the length of time required to complete the learn procedure:

• Heavy traffic. Following too close behind vehicles for long periods of time (more than 40 minutes).
• Stop and go or very slow traffic.
• Mountain roads.
• Constant sharp curves in roadway.
• No traffic. If no traffic is available, the vehicle ahead may need to be added to support learning.
• Limited or no stationary structures on the side of the road. Structures such as street signs, guard rails, mail boxes and parked cars are needed to complete the learn procedure.
• Driving in tunnels.
