Trouble Symptom:
1.Car can start
2.Steering warning light on after car starting
Reasons:Steering column lock module usually damaged when battery replacement.
Trouble Diagnosis:
Use VW ODIS software to diagnose,it get the error code P305300
305300 starter activation return message terminal 50 short to ground/open circuit.
Use multimeter to measure the terminal 3,a bipolar junction transistor THQ33.And reoaur mechanic found THQ33 short circuit.
After TH133 bipolar junction transistor replacement,mechanic found the inner power supply was wrong.Finally,a 8 pins IC chip L4949ED damaged was found,it is low voltage power supply chip.
