On my old Launch CRP123 OBD2 scanner I never got any other DTC's/Codes other than bank 1 manifold runner stuck (VCMA).

Sold it to pawnshop. Saw the Autel Maxicheck MX807 ODB2 Professional scanner at $200.00. More expensive from Autel site.

I factory reset, updated it then plugged it in my Kia OBD2 port.

Several minutes later got all these DTC's/codes.
▪︎B1324 weight classification system (WSC) communication error.
Supposed fixes: replace clock spring,seat airbag connections wires/harness, pins+connections, seat track rail sensors,

▪︎B1378 front driver side airbag (DSAB) resistance too high.
Supposed fixes:replace airbag modules.

▪︎B1382 front passenger side airbag (PSAB) resistance too high.
Supposed fixes: replace airbag module.

▪︎B1511 driver buckle switch circuit open or short to battery.
Supposed fixes: replace seat buckle.

▪︎B1513 passenger buckle switch circuit open or short to battery.
Supposed fixes: replace seat buckle

▪︎B2500 warning lamp failure.
Supposed fixes:
Burnt-out Air Bag Warning Lamp
Faulty Air Bag Warning Lamp
Air Bag Warning Lamp harness is open or shorted
Air Bag Warning Lamp circuit poor electrical connection
Faulty Supplemental Restraints System Control Module (SRSCM)

▪︎B1323 occupant classification system (WSC) failure defect.
Supposed fixes: replace seat occupant weight mat sensor (between foam) & or weight mat sensor module/module (underneath seat),check wires pins connectors, harness, check seat track rail sensors.

▪︎C1260 steering angle sensor (SAS) circuit signal.
Supposed fixes: Faulty Steering Angle Sensor, Steering Angle Sensor harness is open or shorted, Steering Angle Sensor circuit poor electrical
connection, inspect the related wiring harness & connectorss, check for damaged components,look for broken, bent, pushed out, corroded connector's male/female pins.

Not fun to take apart my car. It feel like I'm just looking for trouble on purpose & only gonna cause more bs. I swear if it has t*ts & wheels, it's gonna be a b*tch to deal with.

From the pics, I tried to take as many as I could with each possible DIY fix.

No occupant weight sensor mat? Looked for it. Couldn't locate it. My Autel scanner shows in (graph/ekg/speedometer & number) fluctuations non stop. Shows whenever I add weight of real time movement weight.

I checked all the possible areas that are related to the DTC's/codes. Connections connectors, wire harness, male.& female pins, rust, moisture, worn freyed broken, exposed, caught bonded overly bent stretched torqued wires/connectors. All looked good. I zip tied what was too loose or was getting caught on anything that would or might cause the problems. I made sure that the wires have plenty of wiggle room/play & slack during seat forward middle back, tilt of front Driver & passenger seats.

Driver seat doesn't have an occupant weight classification system module & an occupant weight sensor mat.

Passenger seat does have the occupant weight classification system module & no occupant weight sensor mat.

Rear seat/bench have no sensors, weight mats. It's just a plain foam. The car has never been in any collisions, hits, accidents at all. The carfax report stated no such incidents, reports or any repairs related from dealership or previous owners. I'm the 4th owner. The car wasn't with the other 3 for long. The longest was maybe 2yrs max. Shortest was maybe 4months. Cant remember.

After the best of my abilities I was able to clear all the DTC's/codes. But now I get the effing annoying seatbelt mil. It blinks & sounds off every few seconds for the entire time my Forte in forward motion/driving.

It seatbelt icon/mil/reminder & annoying effing ringing doesn't go off at all. It stays off 100%. It goes off the second I shift into drive/1st gear & thru all 6 gears at any speed.

I can sit in the drivers seat with engine idling & it's stays off. I've removed the front passenger seat 4 times. I'm just pissed off.

As for the runner stuck p2009 bank it was the VCMA. It was completely out. Went to my local junk/salvage got another VCMA for $50 & installed it. Code gone. I bech tested the old VCMA at pins 4&5 with a 9V batter. Didn't move at both polarities. Tested the junk/salvage yard (new to me) VCMA at pins 1&2 it moved counter & clockwise. No more code.

VCMA bench test with 9V battery & alligator clips/jump wires at 4&5. Check both polarities making sure the motor rotates clockwise & counterclockwise.
