Shift Solenoid (B) Control Circuit Low

The Engine Control Module (ECM) commands gear shifts by turning the shift solenoid valves  ON/OFF . When there is an open or short circuit in any shift solenoid valve circuit, the ECM detects the problem and illuminates the engine light and stores the Diagnostic Trouble Code (DTC), and the ECM performs the fail-safe function and turns the other shift solenoids valves in good condition  ON/OFF .

Low transmission fluid level
Dirty transmission fluid
Faulty shift solenoid "B" valve
Shift solenoid "B" valve harness or connectors
Shift solenoid "B" valve circuit is open or shorted

Check engine light
