My 100 is a 2001 LC. For the past few weeks I’ve been getting the occasional VSC Trac and VSC Off lights illuminated on the dash. Turning the vehicle off and restarting usually clears them. If driving while illuminated the engine appears to stumble a bit on acceleration. However, the check engine light is not illuminated and there are no OBD II codes.
Using the jumper method with the under hood diagnostic port I’m getting code 53. FSM says it means ECM communication circuit malfunction.
I’m not quite sure where to go from here. Where is the ECM located and could water intrusion be a possibility? It’s been very wet here recently.
Any thoughts on what to check and where to go from here? I’ve tried doing a bunch of searching but haven’t found any solid answers.
