Toyota Tundra. Manual — part 2834

MONITOR DESCRIPTION

These DTCs indicate an open or short in the shift solenoid valve S4 circuit. When there is an open or short
circuit in any shift solenoid valve circuit, the ECM detects the problem, illuminates the MIL and stores the
DTC. When the shift solenoid valve S4 is ON, if its resistance is 8 ohms or less, the ECM determines there is a
short in the shift solenoid valve S4 circuit.

When the shift solenoid valve S4 is OFF, if its resistance is 100 kohms or more, the ECM determines there is an
open in the shift solenoid valve S4 circuit (see FAIL-SAFE TABLE ).
