monitor description monitor description

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

When the shift solenoid valve SR is OFF, if resistance is 100 kohms or more, the ECM determines that there is an open in the shift solenoid valve SR circuit (See DATA LIST / ACTIVE TEST ).
