Cruise Control

Suzuki Swift 2017
Symptoms
1.yellow triangle icon popup from dashboard
2. Few days later Cruise Control popup from dashboard
And here is DTCs >RBS(Radar Brake Support) C1618 > Sensor Misaligned
BCM B1104 > Luggage Antenna Circuit Malfunctions
BCM B150A Sunload Sensor Circuit High
I want tackle these DTC
Thanks

What is a Sunload sensor ????

Maybe somehow the radar brake support is also used by CC and the proximity sense is a cruise control function or something I don't know what I'm talking about that wish I had the schematic of circuit and maybe a module diagram I need to ask is your CC still operative and does your sensor still buzz

Sunload sensors are used for MVAC climate control. I can’t pull any diagrams for this vehicle, but for the sunload sensor it uses sunlight to determine how much resistance it will provide. It will be a 5V ref and the more sunlight (more resistance) it will lower the voltage. Using this logic, you can use something to cover the sensor to block the light and test it for voltage. See if once it’s covered if the voltage moves up closer to 5V.

No idea it show on diagnostic tool

Ok will check but main concern is cruise control and want tackle the issue. here is dashboard indicator, if there are no issue main screen illuminate in white color

Some vehicles always have the sunload sensor code, especially if scanned not in sunlight. I would ignore that one.

If your car is anything like Nissan's ADAS, your distance sensor may be out of adjustment. That's what the code sounds like to me. That could disable your cruise too. The sensor has to be dead nuts straight, like aligned using a target board and scan tool or else it will not work properly.

Does it still have warranty? Not many aftermarket shops seem to have gotten into that type of work yet.

How can I solve this DTCs
C1618 sensor misaligned
After couple days this DTC is shown( C1690 sensor not aligned and I have data streamed screen shots
Thank you in advance

If there is a issue with the abs to where a code is generated it will dissable cruise control. So you will need to fix the brake system issue.

So do I need to replace break shoes or break fluid??
Didn’t notice any issues in ABS and Break.

You need to have RBS & MFL sensors aligned once that is done your cruise control should work.
