Suzuki 2000 df70 temp warning light turns on.

When you key on, temp lights up and disappears in self-diagnosis mode.
I don't know the cause.

Lamps were still telling you something about the error when you cranked the engine. Error code containes 2 sequnces. 1st sequence has at least 4 flashes as seen on the video. That leaves you with CKP sensors error or fuel injectors error. At least I think so. SM says that 'Check Engine' light blinking in a correct order tells you the problem, but here other lamps are blinking.
I pasted the link from the SM below so you or anybody else from forum can check and overturn my assumptions.

BTW: do you have an option to connect your engine to the PC with SDS? You should get the info much easier that way.
