1. I have a problem with My 1993 Honda Civic DX. It's A/T shift lever is stuck when its engine is starting and its stop light is on.
2. I have checked its neutral safety switch using a multimeter. The voltage is good at P, R, N and D4-1 positions with Key On, and the continuity is good too at all gear position when the neutral safety switch is disconnected from its connector.
3. There almost no voltage goes to the interlock solenoid with Key ON. The resistance of the interlock solenoid coil is about 30 Ohms when the solenoid is disconnected from its connector harness.
4. Could you tell me what reason causes this problem? Is the interlock control unit is default?
An emitter circuit in the control unit must give 12 V to the interlock control solenoid coil at Park position when the engine is starting and stop light is on at normal situation. I think it may be broken. To resolve this problem, the interlock controller should be replaced. What is your point?
Thank you for your attention and help

With Best Regards
