Default Where is the ABS/ESP control module located?

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...

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.

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?
