Speedometer and odometer have stopped working. I have replaced the VSS and they still do not work

Bad connection or failing Speed Sensor. Mentioned on the Suzuki Forums. An auto electrician can check in about 30 minutes.

..

did you connect any OBD2 scan tool and look.
the PCM will tell you if the VSS is dead. flat out tell you.
why no scan the PCM and not work blind./??
the tool is cheap to buy, rent or loan. (or any mech will just do it for free as good will. (no dealers here).

ok, Rodeo, 3.5 2004
3.5L is wrong, dead wrong, 3.2 is my guess.
see here, see country and engines, neither i can guess.

which engine ReALLY ?
Not the Rodeo SPORT , answers below are 3.2L non sport.

Speedo dead. what about Odometer.?????
is replace sensor a statement or a question?
replaced with a "d"
my guess it was a question. and guess.
step 1 and 2 all electrical problems.
1: test the fuses, related. Fuse #11?
2: battery fully charged, at 12.6vdc, not 10v, at 10 electronincs dont work right. fix battery. or charge system.

now how does the 04 work.?
the VSS sensor feed data to many things.
PCM (for fueling data)
Speedometer
Odometer
ABS
supension control unit.
cruise control
etc.

if the odometer works its not the VSS.
see?
the cluster is 100% electronic, ....

VSS is input to Speedo and the odometer is electronic inside
same, so if VSS is bad, both die.
fact.
if only the speedo is bad, then it is bad.

scan the PCM and not guess.
the PCM reports a bad VSS, with 100% assurance.

could be the VSS - vehicle speed sensor .
Speedometer and Odometer
The Vehicle Speed Sensor (VSS) is a gear driven permanent magnet generator. The vehicle transaxle houses the VSS. The VSS generates a sine wave output with a frequency proportional to the vehicle speed.
The Powertrain Control Module (PCM) converts the CKT 389 signal to an output that switches to ground at a frequency of 4000 pulses per mile. The CKT 389 signal drives the speedometer and the odometer. Various other vehicle components use the CKT 389 signal. Refer to Engine Controls.

These guys are breaking parts every time you go there. Would never have replaced the ecu. It was the crank sensor to begin with. Replace the vss yourself. It is easy.

Your vehicle does not have a traditional speedometer cable. Instead it uses a VSS (Vehicle Speed Sensor) to read speed of the vehicle below is a short test to help you determine if it is the VSS that has failed.

SPEEDOMETER VEHICLE SPEED SENSOR TEST

1. Press and release trip odometer button until function number 6 appears in display window.

2. Turn a front wheel and observe display (pulses are added to number in display. Check impulse signal for speedometer vehicle speed sensor. If 7 pulses are generated per wheel revolution, vehicle speed sensor is okay.

3. If specified number of pulses are not generated, check for open in wiring harness between speed sensor and instrument cluster. Repair wiring harness if necessary. If wiring harness is okay, replace speedometer vehicle speed sensor.

Usually the ABS computer knows what it is doing. You may want someone to hookup a scanner to the ABS test port.
When I had my speedometer and odometer act up, it turned out to be a bad alternator. You might want to check yours.

There is no Speedometer cable on a 2002 Jetta. You have a VSS (vehicle speed sensor) I would have someone check the codes on it and see if the VSS is the problem.

it is likely the VSS, vehicle speed sensor on the top rear of the trans. one 10 mm bolt, but often the VSS won't come out due to corrosion. spray with penetrating oil.

The VSS sends a signal to the speedo cluster. Cluster converts signal and sends it to speedo and odometer and also to engine computer.

If your cruise control also does not work, it is VSS.

Try prying back and forth at base after soaking.

I have a 99 accord and my speedometer and odometer did not work. The problem was the VSS vehicle speed sensor. The VSS is located on the transmission. Once I replaced it everything worked fine.

If all the connection and power supplies to instrument cluster are ok,I suspect that the speedometer or instrument cluster is faulty but before you replace it, make sure the gear inside the transmission that drives the VSS is in good.
