Monitor Description
WARNING: This page is about a different car, the 2008 Lexus IS F. However, it is still accessible from the selected car via links, so may be relevant.
These DTCs indicate an open or short in the shift solenoid valve SR circuit. When there is an open or short circuit in any shift solenoid valve circuit, the TCM detects the problem, illuminates the MIL and stores the DTC When the shift solenoid valve SR is ON, if resistance is 8 Ω or less, the TCM determines there is a short in the shift solenoid valve SR circuit
When the shift solenoid valve SR is OFF, if resistance is 100 kΩ or more, the TCM determines there is an open in the shift solenoid valve SR circuit (See FAIL-SAFE CHART )
