Mode F1 (Code History)
Mode displays trouble codes and description. See Figure. Ignition cycle information is useful in determining reason vehicle is in for service. If display indicates zero ignition cycles since code was set, fault is currently present.
EBCM keeps track of ignition cycles and will automatically erase any code information if no ABS faults are set in 50 cycles. This information is useful to determine if intermittent condition exists.
Vehicle speed information and BRAKE light switch information can be used to duplicate fault if an intermittent fault caused code to set.
ABS state information is useful in determining driving condition of vehicle when code was set.
