Figure 10 EGR Lamp (21/24EKOZD 60 Hz Models Only)
The EGR lamp is located on the side of the junction box for 21/24EKOZD 60 Hz models only. See Figure 10. Under normal
operation, the light illuminates for approximately 1 second at startup to indicate that power is available to the EGR and then, the
light goes out. If the light pulses more than one time, verify that the ECU module is properly connected and verify that the EGR
valve is properly connected. If all connections are good and the light continues to pulse, contact an authorized Kohler
distributor/dealer for service.
