What does this code mean SHT HI 14 103 on a 2007 Freightliner

not possible to answer as freight liners use 3 different engines and 3 different transmissions ( 3 different specific code lists) so unless you can supply all the information when asking a question , the best answer is to take it to a service dealer and have the codes read and explained to you

Do I have a proportional valve?

no (and yes) the car has ABS.
if zero fluid there, then the ABS modulator is real bad.
or its input bad called the master cylinder.
the MC has 2 parts inside, one can fail and other ok.
to finds this is easy, learn to crack lines.
means loosen the flared fittings. or the bleeds where found.
my guess you mean that both rear bleeds are dead.
so move forward and crack (loosen the fittings so they can leak)
person to pressure brake, key off is ok, brakes work with no key on.(manual brakes if no blockages)
so if the lines are dead on ABS MOD but good in front
the ABD mod is toast (rusted inside)
when did the brake work right, list week .last year, or?
the modulator is called in jeep the HCU
see those fittings? ccw is loose.

the fsm is free, read it yet,?
WK is same car.

posted over 300 times this free fsm link.

i only have questions.
1: did you remove any parts.?
2: did you attempt to bleed the brakes and not read the words in the FSM on how to do that first>
3: or say car was parked for 1 year.
then you found brakes in rear bad. or have ABS or Brake failure lamps glowing??????
or the scan tools show errors?
then decided to check for fluid pressure on rear of car using , stand methods.,
4: were both rear caliper lacking pressure, or just 1 side.
the post implies both..."brakes". but>>>>?????

as you can see , us knowing the full story,
is a win/win... the context of your work.

Check engine light came on

What do you mean "can't find code"? If the check engine light is on, there is a fault code stored in your onboard computer - that's the way it works. If you are using a generic OBD code reader, that is most likely the reason you cannot find any codes. You need to use a scanner that has the correct software to access your ENTIRE computer network, not just the "continuous memory" or "generic" side of your computer system.

The window problem is a seperate problem and must be diagnosed accordingly.

Have a 94 chevy blazer 4x4 with vortec eng. can keep it running it is getting spark and gas will start but only runs for a moment then shuts ofc, i have replaced the starter, plugs wires, cap and roter,...

Sounds like it could be the EGR Valve.If you can drive it and get up to 45-55 mph and it runs smooth then its the EGR valve that is stuck in the open position.I would take the EGR Valve off and clean the carbon out of it using a non-chlronated brake cleaner.

Vehicle is a resto-mod 1970 Challenger. Original front drum brakes replaced with ECI disk conversion package. After driving a short distance front brakes begin to drag, eventually remaining almost fully...


I doubt the problem is the calipers as I would not expect them both to be faulty.

I do not think it is the proportioning valve.

From the symptoms you have described it sounds very much like the master cylinder is faulty. If the car is a resto mod with upgraded brakes I assume the original master cylinder has been replaced with some late model unit, either new or used.

I could not comment further without inspecting and testing the car. Some resto mods are carried out by amateur car enthusiast (as you know) rather than professionals and amateurs frequently undertake brake modifications that should be left to the experts.

I would be taking the car to a competent brake specialist to check it out. especially as the braking system has been modified with an aftermarket kit. This is not a DIY task and I would advise you not to try fiddling with the braking system in an attempt to fix this problem yourself.

Hi, My 96 jeep cherokee is running rough at idol and backfires. I replaced the fuel pump, plugs ,cap, rotor, intake air contorl mod.and wires. I cand seem to find egr. valve. can you please help?

You have a vacuum line off somewhere, or the egr valve is leaking at idol, or you have manifold vacuum hooked up to the egr valve, make sure the vacuum line going to the egr valve has no vacuum at idol, only during acceleration.
