I have let my kids drive the 06RL now that they are driving. It has become their car. My son has a habit of playing music in the school parking lot while waiting for class or skipping class. He has successfully killed his first battery. It was 4 years old so, time to replace anyway. Since replacing the battery with an AGM one, he still plays music, but he tries to reduce power consumption while doing so. He turns off the AC, dome lights, Nav display and powers the stereo in ACC mode. He STILL runs the battery low. I later found out he left the seat warmer in low. ANYWAY, he called with the great news that the check engine light came on. There were several low voltage codes that I cleared in various modules. I charged the car and drove it today. Two problems came back. The check engine light came back on and the driver's seat will not stay at the selected height. It sinks all the way to the floor. Here is a photo of the DTC code. Does anyone know what this one means? I can't find 162_18 in the service manual.



And, any help with the drivers seat? It will not stay at the memorized height. The motors work fine it just slowly sinks to the floor.

 

All I can tell you is that this car is infamous for displaying all kinds of squirrelly electrical demons that have driven owners and dealers nuts, only to discover that they were all caused by low voltage. Since you didn't have these problems until you had that one, be sure you no longer have low voltage before moving on to suspecting anything else. Also, kill your son and eat him. The young ones taste like veal.

 

yup, charge up the battery on a battery tender overnight, reset the codes and drive around to see if they show up again

 

Well it’s a new battery and charged up all night. Now I’m being told the VSA light has come on. Sounds like electrical gremlins. I’m thinking loose connection or bad battery. At least I hope so.

I’ve since cleared all codes and verified a good better but now the emissions DTC has appeared again. Can anyone tell me specifically what the code error means? Can I ignore it for the summer? Because the car will be out of my control for a few months.
