Answer= on the top of the differential there is a speed switch which . you can check the switch by unplugging it and put an ohm meter across the prongs on the switch if it reads infinity ( open) it is bad ( a good switch will read about 1.8 K ohms of resistance) and will cause the abs and brake lights on the dash to stay on it will also will cause the speedometer not to read below about 20 MPH. the switch is a dealer item - cost about 40 dollars. the switch is easy to change and take about 10 minutes.Answer
You might want to take a look at the speed switch - its a pickup switch used to monitor your speed
Had the same problem on my 1999 Dodge Ram 1500 4x4. ABS and BRAKE light on, no speedometer/odometer at lower speeds and the CHECK ENG light on. Used scanner at Auto Zone to download fault codes; fault code linked to malfunctioning speed sensor. Went to dealer and picked up new differential speed sensor ($45), installed it and presto, everything good to go. I chose not to disconnect the battery during sensor replacement so the CHECK ENG light remained on for a few trips before the PCM (computer) cleared the speed sensor fault from memory. The CHECK ENG light then extinguished.
frist the brake light looks like its on but its just the glow of the antilock light it is very bright. the antilock is on your rear axle needs replaceing.
Just connect it to one of the brake lights hot lead, and ground it to the truck.
need to make sure power is getting to the brake light switch and abs unit
2996 dodge Dakota ABS lightIf you notice the speedometer is also not accurate the problem is most likely the rear ABS speed sensor. This is located on the top of the rear differential housing of the truck. It is simple to change, and caost about $45.
A 2001 Dodge truck does not have a speedometer cable. The speed signal comes from the rear axle speed sensor. (the sensor on top of the center of the rear axle)
The speedometer does not have a cable on a 1994. It is run by a sesnor on the rear of the trans/t-case.
it means that you have a bulb out somewhere on your truck.... IE backup light, brake light, turn signal, running light.. etc etc..
likely thr rear abs speed sensor in the differential, usually costs about $35 at the Dodge dealer and takes 20 minutes to change yourself, then disconnect battery for 10 seconds and the system will reset
3rd brake light or rear brake lights?
The brake light switch relay for your 1997 Chevy truck is located beneath the drivers side dashboard. The brake light relay switch will be above the brake pedal.
There are dozens of possible reasons. I'd have to examine your truck's electrics, pedals and electronics to be sure. Take it to a mechanic.
If the abs light is on, then you might have a rear axle speed sensor issue. If not, then you have a cluster problem.
no, the offset around the brake caliper is different.
Where is the brake light switch for 2003 hd Chevy truck As far as I know, all brake switches are on the top of the brake pedal arm.
on the brake pedal
Why would my 1984 Dodge pick up truck stall at the light when I stop
If the grinding sound seems to be coming from the speedometer and grinds faster as your speed increases, the likely cause is the speedometer cable. At least some 1990 Dodge trucks (mine) have electric speedometers Len
bad brake light switch
check you brake fluid level.
how do you chage bracke pads on a 355 2004 dodge diesel truck
all brake light switches are connected to the brake pedal --- any car or truck or van
it could be the brake light switch that usually contacts the break pedal when you depress the brake pedal. check that out first.
The abs uses the brake fluid from the regular brake master cylinder.
