I finally got round to investigating why the shift lock solenoid never worked on my 2.4 LN130. Every time I needed to shift out of Park, I had to press the red button.
Before anyone suggests a brake light had failed, I already checked
In the workshop manual, it showed the Shift Lock Computer (SLC) lived next to the shifter, under the trim. Removing the trim was easy, so I then checked all the inputs to the SLC as per the workshop manual. Everything measured fine.
The only thing it could be was the SLC itself.
Opening up the case revealed a fair amount of oily gunk covering the circuit board. After cleaning that off with some alcohol, I could see that the board was quite corroded in places.
One track was completely etched through, so I bridged it with a length of wire. I resoldered the most dodgy looking joints too.
Cleaned up quite nicely.
Plugged it all back in again, turned on the ignition, pressed the brake pedal and saw the solenoid operate
Another job jobbed
