Main code 46 indicates that an overcurrent condition exists in one of the switches sending power to the
transmission control solenoids.
Active Indicator Clearing Procedure:
1. Probable cause is a wiring problem. A solenoid wire is probably shorted to ground or the solenoid
has a shorted coil which would cause an overcurrent condition. May also be an ECU problem.
2. Follow the troubleshooting steps for code 44 XX.
