CVT Symptom Troubleshooting

These symptoms DO NOT trigger Diagnostic Trouble Codes (DTCs) or cause the [D] indicator to blink. If the Malfunction Indicator Lamp (MIL) was reported ON or the [D] indicator has been blinking, check for DTCs. But if the vehicle has one of the systems in the following chart, check the probable cause(s) for it, in the sequence listed, until you find the problem.

Symptom 
Probable cause(s) 
Notes 
When you turn the ignition switch ON (II), the D indicator comes on and stays on or never comes on at all 
A problem in the D indicator circuit 
Shift lever cannot be moved from P position while you're pushing on the brake pedal 
A Problem in the shift lock system (interlock system) 
Ignition key cannot be moved from ACC (I) position to LOCK (0) position, when you're pushing it with the shift lever in P position 
A Problem in the key interlock system (interlock system)
