Toyota Repair Problems? Ask a Mechanic for Answers ASAP
After replacement of the battery this message is still displayed? "Transmission P lock mechanism is Abnormal"
This is a new battery correct?
Other than the warning message and the master warning light are there any other lights on? (Check engine light).
Can an audible click noise be heard when you select the park position( Noise of the park pawl engaging).
Have you driven this car long enough to charge up battery, in case it was weak( sitting on the dealer/store shelf to long)?
There is the shifter part of the system, which sends a signal to active the parking lock relay. Then there is the actuator side of the system, which is the 12v supply voltage which goes through the parking lock relay and engages actuator. A voltage test needs to be preformed at the control side of the relay plug terminal, when the park button is pushed there should be 12 volts at the control side of relay plug. If not suspect shifter or wires to it. The other side of the relay, the actuator side should always have 12 volts at one terminal and continuity to ground on the other. A simple jumper between these terminals would engage the park lock actuator, if not suspect wires going to it( since you already replaced lock actuator).
If they verified no signal at park button side of relay then yes I would probably suspect shifter.
I believe is the dashboard wiring harness that connects to it, I can check on this though.
I just reread your post, your talking about the shifter, as in the one in the car, the gear selector joystick? Right
Yes dash board wiring harness is what connects to it.
