Dtc codes p1820 - 2012 Kia Sportage Base 4dr SUV 2.4L 4-cyl. 6-speed Manual

The first thing to do would be to hook up a scan tool that can communicate with the Roof door module (RDM) an check for code's (DTC'S) . Can set a bunch of different code's

DTC BThe roof door module (RDM) checks the outer latch latched signal circuit, at least once every 200 milliseconds.
The folding top outer latch position switch is supplied with a constant ground source.
When the switch is active, the RDM will detect a switched ground signal on the folding top outer latch position switch latched signal circuit indicating that the latch is latched.

DTC B3685
Without a factory or professional scan tool you can't read these code's . Advance , auto zone , pep boy's etc .... can't read these code's . Your best bet take it to the Dealer or someother qualified repair shop.

u10140 ??? too many numbers, should only have 4 at most . U code's are GMLAN network code's . Do you know what a serial data communication network is ? All the modules , PCM/ECM , BCM , instrument cluster , ABS , SRS etc... all take to one another (share info.) on this data network . Computer talk. U code's can mean a module stopped talking or a problem with wiring etc... DTC U0020
DTC U0073 or U2100
DTC U0100-U0299
DTC U1500
DTC U1814
DTC U2099
DTC U2103
DTC U2104

Your best bet , take your vehicle to a qualified repair .

Engage solenoid in transfer case may have failed. Check wiring and try to hot wire solenoid to see if it works.

Where is nin Sensor located in 1az engine sienta

Have the codes checked ! Do you know what codes are ,What the light is for ? The light is to warn the driver that there is a problem in the ABS system . Have the codes checked before replacing parts ,the code will point you in the direction to go .This system can set numerous DTC'S
DTC C1211 DTC C1214 DTC C1217 DTC C1218 DTC C1221-C1235 DTC C1236 DTC C1237 DTC C1238 DTC C1242 or C1243 DTC C1248 DTC C1251 (w/F45) DTC C1254 DTC C1255 or C1256 DTC C1261-C1274 DTC C1276, P1644, or P1689 DTC C1277 or P1571 DTC C1278 DTC C1281, C1283, or C1286 DTC C1282 DTC C1284 or C1285 DTC C1287 or C1288 DTC C1291 or C1293 DTC C1294 DTC C1295 Maybe your best bet would be to take your vehicle to a ASE certified repair shop or the dealer

It needs a service.

Problem with 2001 Toyota 4Runner? right? USA CAR?????
what engine, what displacement, how many cylinders?
gasoline or diesel???????????

p1820 (P1 is a toyota only factory code so don't read about fords etc)

the FSM covers all that ,as does alldata.com
how it works is complex, as are the monitors.

did you pull that code with your tools or Autozoned."?
what tool?

my listing ends at 1780. (a bad source, i guess)
2 car pros same answer.
i cant find it , but do answer all questions in bold please.

the 1 millionth post now. for a bricked radio (or Nav head)
and not one person bothered to read the operators guide, its there.
you forgot to write down the radio codes day one. ooops.....

a trip to toyota or any key shop with special license ,solves this.
take radio serial number with you and proof you own the car.

There is no reset , if security light is lit there is a problem with the anti-theft system .Should have it checked for DTC'S - diagnostic trouble codes . Could have 8 different B - codes
DTC B0685 DTC B2955 DTC B2960 DTC B3031 DTC B3033 DTC P1626 DTC P1630 DTC P1631
You would need a professional type scan tool to read these type codes , not an OBD 2 code reader .

"The PCM controls the torque converter clutch (TCC) solenoid valve pulse width modulation (PWM). The solenoid controls the hydraulic fluid for TCC apply and release. When the TCC is applied, the engine is coupled directly to the transmission through the TCC. The TCC slip speed should be near 0.

If the PCM detects high torque converter slip when the TCC is commanded ON, then DTC P0741 sets. DTC P0741 is a type B DTC.

Conditions for Running the DTC
• No TP DTCs P0121, P0122 or P0123.

• No VSS DTCs P0502 or P0503.

• No AT ISS DTCs P0716 or P0717.

• No TCC stuck ON DTC P0742.

• No IMS DTCs P1820, P1822, P1823 or P1825.

• No TCC PWM solenoid valve DTC P1860.

• The engine run time is greater than 5 seconds.

• The time since the gear select lever change is greater than 6 seconds.

• The IMS indicates D2, D3 or D4.

• The transmission gear ratio indicates 2nd, 3rd or 4th gear.

• The transmission fluid temperature is 20-133°C (68-271°F).

• The TP angle is 10-50 percent.

• The engine torque is 43-215 N·m (32-159 lb ft).

• The TCC solenoid valve is commanded ON.

Conditions for Setting the DTC
TCC slip speed exceeds its limit for a given torque for 5 seconds.

Refer to Torque Converter Clutch Slip Speed .

Action Taken When the DTC Sets
• The PCM illuminates the malfunction indicator lamp (MIL) during the second consecutive trip in which the Conditions for Setting the DTC are met.

• The PCM inhibits 4th gear if the transmission is in hot mode.

• The PCM records the operating conditions when the Conditions for Setting the DTC are met. The PCM stores this information as Freeze Frame and Failure Records.

• The PCM stores DTC P0741 in PCM history during the second consecutive trip in which the Conditions for Setting the DTC are met.

Conditions for Clearing the MIL/DTC
• The PCM turns OFF the MIL during the third consecutive trip in which the diagnostic test runs and passes.

• A scan tool can clear the MIL/DTC.

• The PCM clears the DTC from PCM history if the vehicle completes 40 warm-up cycles without an emission-related diagnostic fault occurring.

• The PCM cancels the DTC default actions when the ignition switch is OFF long enough in order to power down the PCM.
