Knock Retard

Scan Tool Range 0.0 degrees to 25.5 degrees. This indicates the amount of spark the PCM is removing from the IC spark advance in response to the signal from the knock sensors. The traction control system Desired Torque signal from the electronic brake and traction control module (EBTCM) may cause knock Retard to display a value greater than 0.0 degrees if traction control is active.
