1. Check the condition of all EGR system hoses and tubes for leaks, blockages, cracks, kinks and hardening of rubber hoses. Repair and correct these conditions before performing any tests.
2. Be sure the hoses at both the EGR valve and EGR valve control are connected to the proper fittings.
3. Be sure the electrical connector is firmly connected at the valve control.
4. To check EGR system operation, connect the DRB scan tool to the 16-way data link connector. The data link connector is located on the lower edge of the instrument panel near the steering column.
Refer to the appropriate Powertrain Diagnostic Procedures service manual for operation of the DRB scan tool when diagnosing the EGR system.
5. After checking the system with the DRB scan tool, proceed to the following EGR Valve Leakage and EGR Valve Control Tests and repair as necessary.
