Where is the ABS/ESP control module located? My awd and lock light are both on all the time and I pulled codes
C1075
U0123
C1057
U1114
U114
U0126
U1021
from the awd control module. When I start the car I see no ABS light and when I hold the ESP button nothing happens. Before I bought this car someone else took the front end and some parts off and I'm assuming the ABS control module is gone!

ABS control module is part of the ABS pump. If thats missing, you have a bit of a problem. Its attached to the ABS unit and is damn difficult to get off. If it has been taken off, then a new ABS unit will be required, and it needs a factory scan tool, or a high end unit to program it to work on the car.

C1075 C1057 are solenoid codes
U0123 yaw sensor
U0126 steering angle sensor fail
U0114 4wd control module comms fail
U1114 Charging system voltage out of range? not sure on this one, depends on Suzuki model
U0126 Steering angle sensor loss of comms to ABS module
U1021 loss of comms to ABS module

I suggest you check the power supplies and grounds to the ABS unit, and make sure the plugs are ok and no pins are bent.
Check the ABS fuse under the hood in the engine bay fuse box, it could be that simple. All these codes point to no or part power at the ABS module.

Reply from 2013GV quite extensive. However, Josh128, some details seem to indicate you have the electric power steering...that we do not have in North AMerica. Can you fill up your profile with location and accurate details of your car.

electric or hydraulic assist is immaterial, SAS is "usually" on the column behind the steering wheel to sense said angle away from "straight ahead" to calculate braking required for stability control.

If the front section was messed with, the clock spring may be suspect...

... Philip
This is a 2009 Suzuki SX4 AWD Manual. It doesn't have electric power steering. Are you talking about the SRS clock spring behind the steering wheel airbag? There's nothing wrong with the airbags. The ABS is working actually, the light comes on when key switched to ON and I tested it on snow today. Nothing happens when I hold the ESP button because I forgot that the instrument cluster is from a automatic that wasn't equipped with ESP so no light.

Now my new question is where is the AWD control module located? I didn't see any fuses for it. With all those codes it seems like something isn't plugged in or a wiring issue.

ok...on models with esp then (Tech, JLX in canada) . Not used on mine (JX) . No ESP.

Steering angle sensor (SAS) not SRS wihich is Supplemental Restraint System (airbags in other words) is static on the column, "clock spring" is part of SRS and shouldn't affect it. This model should have plain hydraulic assisted power steering, not electric. This depends on location tho. Electric wasn't common in 2009 apart from the swifts i think.
yaw sensor is usually located near the handbrake lever, rear of gear shift, and is at the "rotational centre" of the car, this is so the one sensor can do X, Y and Z axis measurements. You may find the SRS ecu in the vicinity as well as this has its own internal "Yaw" sensor to detect rollovers.

Your last comment now makes sense, and if i suspect whats happened, these codes are all deriving from a faulty or mis-matched dash as someone by the sounds of things has fitted the auto one into a manual and hasn't reprogrammed things to recognise the different setup. Change a dash, its a reprogram. I'm surprised it started, most cars won't until its been loaded into the BCM, TCM 4WD and security modules. This would explain the "comms" codes, and the 4wd control module comms fail.

Check your fuses, 4WD is usually located near the BCM, don't ask why, Suzuki seem to do that, passenger floor outer side panel is the common spot.

yep, model specific. Some had ESP, most didn't back then in the dark ages. ;)

The instrument cluster, airbag control module, 2 front crash sensors, 2 front air bags, and seat belt pretensioners are from a 2007 SX4 AWD Auto not equipped with ESP. It's stuck in 2wd. So do you think these codes are caused by the instrument cluster not being programmed to the car?

well...not all are created equal. ESP on my other car is a total mistake and causes a lot of havoc in situations where is it not needed at all, like stalls in trafic circles at low speeds on dry surface and in tight cornering . It is a common thread on the related other forum. I've no idea how well it is perceived in the SX4 but the experience with KIA is a disaster. So....esp IS the dark era there....and happily, there is an OFF button!

I suspect theres a programming issue and it will be related to the dash and quite possibly additional wiring damage. Sounds like it was in an accident. usually if its bad enough to trigger air bags its enough to bend the chassis and the car should be taken off the road permanently. You need to see a suzuki specialist and have them diagnose it properly as they will have the genuine scan tool to reprogram things. (if its possible)

In most situations, Auto and Manual versions are not interchangeable and since the equipment you had installed was from a non ESP model then it may never work. This could also explain the lack of 4WD as it relies on the esp to trigger that into operation in auto mode.

No this car wasn't in an accident. Another SX4 was and parts were taken off this car to rebuild that one. Then parts were taken off another SX4 to rebuild this one. I don't think that the auto instrument cluster is the cause of those codes. This car does have ESP, just not an indicator light in the instrument cluster.

I'm pretty skeptical that ESP would make your car stall in traffic circles. I don't think it works at very low speeds. ABS doesn't work under about 5mph. ESP saves thousands of lives and shouldn't be turned off unless you have a good reason. It helps you regain control in over/under steer conditions.

and the instrument cluster ECU communicates via can bus to the 4WD, ABS/ESP, BCM and engine ECU modules. So, if the dash doesn't have ESP set up in its ECU, then the rest of the car won't enable it. You need to investigate the comms system and the fail safe tables in the service manual to see whats common to your issue. At present, its the dash.

I forgot to plug in the yaw sensor that's mounted directly above the airbag control module. Total retard moment. Then I started the car, the awd and lock lights went out. The drive mode switch works as intended. It's winter time here and the ABS definitely works. No airbag light. I don't think the instrument cluster needs reprogrammed. Since there's not an ESP light, I don't know if that works. I'm not going to test that on the road. I'm surprised one sensor caused all those problems, or at least the awd to not work. Thanks for your help

YAW sensor is common to all these, I didn't think you would have been near it, dumbass me
