Hyster H3.0FT:
Starter interlocked seat sensor

Hi everyone,

Working on a all new H3.O FT (P177BO2291N) !

I have check, of course, all the harness and connectors. Every thing seems to be ok. The 3 green LED on the Seat belt seq module are on. I am on the seat with the seat belt on too, but the message is still there.

I'm looking for the seat sensor voltage on the VSM (CPS9, pin 11).

With the Display and also with my DMM, i find 0,59 Volt... Is that correct ?

Any help will be appreciated.

Thank you.

this is the hyster internal option impact sensor
The impact sensor said starter interlock impact sensor, and it seemed to clear as soon as I had entered the password for service level and exited. I also have gone back through the truck general items setup, and tried with the impact sensor both activated and deactivated. A couple of times I had an error about not being able to write the hard impact settings. but after a few attempts that error did not return.
I also note that I have a greyed out setting for "BLM" in 'bank 1 fuel control" and bank 2 fuel control. (what does the "BLM" stand for, here?)
I am now also seeing that the second O2 sensor is "na" although it has one and changing it made no differences.
I am leaning to a messed up "hard" setting in the computer, but am about to start checking "pin to pin" from the ECU.

"it's not rocket surgery"
didn't it also say something about the hydraulic controls being out of spec or return to neutral? I get no other info.

I have had the mini lever board cause this (fingertip control)

I had that starter interlock truck disabled once when one of the transmission solenoids was stuck, but it also gave codes for pressures were incorrect.

How did you clear the impact lockout? I believe just disconnecting the sensor will not clear the truck to start.

I am having a similar problem with a no crank "starter interlock truck disabled message on a s50ft (f187v, 2.4 GM). I welcome any advice...
The service call started with an error about the impact sensor, cleared that and disabled the impact sensor.
starter cranks and truck runs if starter is jumpered to engage the starter solenoid. relays are tested on known good truck, and can engage starter from starter solenoid connection in pdc.

Problem solved!!

In fact, there is no problem here.

On this new generation of forklift, there is a "Seat belt sequence module". It's the little box with 3 green LED, near the VSM.

To start the engine, we have to sit on the seat first, then, to lock the seat belt, and only after we can start.

Fact of the week
The concept of Daylight Saving Time (DST) was first implemented in Port Arthur, Ontario, Canada in 1908. The first proposal for DST, however, came in 1895 from New Zealand entomologist George Hudson who valued extra daylight so that he could hunt bugs after work during the summer months. He suggested a two-hour daylight-saving shift.
