Detection Condition

DTC is set when Powertrain Control Module (PCM) detects low voltage from Variable Tumble Control System (VTCS) solenoid valve with VTCS solenoid valve off. This is a continuous monitor (CCM). MIL illuminates if PCM detects malfunction condition in 2 consecutive drive cycles. Pending code is available if PCM detects malfunction conditions during first drive cycle. Freeze Frame Data is available and DTC is stored in the PCM memory.
