I wish i could sleep any time after 30 years of night shifts while my circadian rhythm was messed up bad

As a former long distance truck driver with timeslots to meet, I'm hearing ya.

I've slept in the back of an M113 (battle taxi) going through the bush

inputs.pdf inputs4.jpgSo all dcv valves tested the same at 102ms,seems strange they are all the same.i jumped the pins as suggested but didnt seem to make much difference 'there is 12.7v at pin 37.notice the inputs dont show pressure'and almost nil voltage[wonder were this is measured] and main relay is off despite being jumped.My next is i am going to have a look at the bottom of the fuse box not sure that pin 30 is looking all that healthy.any thing else i should look at.

Can someone confirm the centre bottom is the correct pin to jump 30 there dosnt seem to be contacts in it.

My apologies, i was carried away and forgot that those relays are that type, 30 - 87 are the two parallel ones above that emply slot, bridge those then you'll get full range readings cos as long as the relay's contact is not closed the ECU has no main feed so all the readings are irrelevant

you had me going there,63 year old eyesight didn't notice until i put theMagnifying glass on it,will try tomorrow.

test5.csv test5 jpg.jpghope this works.also tested the dash light by pulsing it flashed.cleared faults and it came right back.is pump pressure ok.seems an issue with upper decelerator were to start.

or perhaps it is the bottom sensor.this from the msv docs.

Upper lateral accelerometer/gravities: A capacitive acceleration sensor located on a bracket in the roof lining above the rear view mirror. It is driven by a 5.0Vdc supply from the ACE ECU on pin 18 of C0647 on a yellow / red wire. The buffered output is 0.25 -4.75Vdc which returns to the ACE ECU on pin 17 of C0647 on an orange / blue wire. The sensor can measure ± 1.14g. It is fed with earth from pin 34 of C0647 on a yellow / green wire. Its input is used for 'head toss' correction and fault detection in conjunction with the lower accelerometer. With the vehicle on level ground with all the doors closed, both accelerometers should read ± 0.01g after calibration: After normal usage, the difference between the upper and lower accelerometers could be as much as ± 0.15g.
Lower lateral accelerometer/gravities: A capacitive acceleration sensor located on a bracket attached to inner sill panel under RH front floor. It is driven by a 5.0Vdc supply from the ACE ECU on pin 12 of C0647 on a yellow / black wire. The buffered output is 0.25 -4.75Vdc which returns to the ACE ECU on pin 15 of C0647 on an orange / grey wire. The sensor can measure ± 1.14g. It is fed with earth from pin 34 of C0647 on a yellow / green wire. While two independent accelerometers are used, this is the primary sensor used to measure acceleration on the vehicle. The sensor's outputs are fed to separate A/D inputs of the ACE ECU's main microprocessor. With the vehicle on level ground with all the doors closed, both accelerometers should read ± 0.01g after calibration: After normal usage, the difference between the upper and lower accelerometers could be as much as ± 0.15g.
