From the 2000-2001 Electrical Troubleshooting Manual
"The T.O.D. control unit receives an input from the ABS system, when active, to apply voltage to the clutch solenoid (transfer).
Are your ABS related fuses good? CB-13, CB-16, EB-17?
(CB-4 must be good if your ABS light is on.)
Is the Code 13 a reference to a P0713 code (Transmission Fluid Temperature - TFT) Sensor Circuit High Input?
