WARNING: This page is about a different car, the 2007 GMC Yukon XL, 2007 GMC Yukon, 2007 Chevrolet Tahoe, 2007 Chevrolet Suburban, and 2007 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
- Turn the main function switch to the CODE position.
- If power is interrupted prior to the recording of the 7-character code, the code will be lost and the flow rate test will need to be repeated.
- The flow test must run for a minimum of 8-10 seconds and be above 0.5 gpm for a code to be generated.
- Record TESTED flow rate, temperature, cycle and seven-character flow code information on the repair order.
