Hello all,
I'm troubleshooting the cruise control on my 1994 Land Cruiser. I've searched the forum for great tips and am at the point where I have extracted the stored code in the cruise control ECU.
The stored code is a 12, which points to three possibilities according to the FSM:
1: the actuator itself. I have disassembled it and it looks great,. practically new. I've assembled and reinstalled it.
2: the stop switch. This is where I'm at currently. I've readjusted the stop switch several times in varying positions. I have removed it and removed the blue cover which is easily removed by bending two metal tabs. I blew compressed air through every crevice I could, reinstalled it, and still have an issue.
I'd hate to purchase a new brake light switch just to have the problem lie elsewhere. Has anyone disassembled the switch completely? It is held together by the metal casing having it's edges bent over the black plastic body. This seems more difficult to remove riskier. The black plastic body looks to be easily damaged.
3: if the above checks out okay when I figure out how to check it, the last step in the FSM is the cruise control ECU being he culprit. It is also very possible the the wiring between the ECU, actuator, and/or stop light switch is damaged as well and I will check that eventually too.
Anyone have any input as to completely disassembling the stop light switch?
Thanks,
Jon
