Code 24 is a ground speed sensor error. Ecu isn't getting a signal from it. the sensor is on the forward side of the transmission on the lower portion near the starter for the engine. Check the wiring coming out of the sensor & up to the main harness. If it's OK the sensor may need to be replaced.
Found the manual. The manual says the engine must be running above idle speed for the ECU to recognize the ground speed signal sensor. Maybe the ECU doesn't recognize the engine speed?
BTW, two long and one says the ECU is not getting the proper signal fro the MAP sensor.
thanks for the info. Do you know if there is a voltage reading I can take at the plug on the ground speed sensor to know if the ECU is recognizes it?
Thanks
