INSERT 7C9539 - Caterpillar

Use this procedure to troubleshoot a detonation occurrence. Also, use this procedure if one of the following event codes is active or logged.Detonation occurrences will only limit the amount of gas that can be substituted in to the engine. The control system tries to reach the requested substitution level, but the primary focus is to protect the engine by reducing the actual amount of gas that is substituted when a detonation event occurs.
