PROBLEM
The current software in the ECM on certain 950G, 962G, 966G, 972G, and 980G Series II machines does not take the engine to low idle if the signal of the throttle position sensor is lost. This will cause loss of engine speed control, which could cause personal injury or death.AFFECTED PRODUCT

Dear Caterpillar Product Owner:
New engine software needs to be installed on the products listed below. The current software in the ECM on certain 950G, 962G, 966G, 972G, and 980G Series II machines does not take the engine to low idle if the signal of the throttle position sensor is lost. This will cause loss of engine speed control, which could cause personal injury or death. You will not be charged for the service performed.
Contact your local Caterpillar dealer immediately to schedule this service. The dealer will advise you of the time required to complete this service. Please refer the dealer to their Service Letter dated December 24, 2001 when scheduling this service.
We regret the inconvenience this may cause
you, but urge you to have this service performed for your added safety
and satisfaction.
