Overview:
Fault Code 46 indicates an electrical failure of the solenoids that control the Splitter.
Detection:
Starting at key on and throughout operation, the Transmission Controller constantly measures this circuit. Depending on the reading, a failure mode of short to battery, short to ground, or open circuit is detected.
Fallback:
This fault causes a 9-speed fallback and the transmission stays in either a low split or high split.
Possible Causes:
1) Splitter Valve
2) Transmission Harness
3) Transmission Controller
Shop Talk:
Key on. If the fault is present, the system should automatically detect the problem and set the code. If the fault is not present at key on, operate the vehicle and attempt to duplicate the driving conditions that triggered the fault code. Possible triggers include heat, vibration.
