GM Development programming system, aka DPS, is an in-house software that General Motors technicians use to develop software for GM vehicle electronic modules. DPS functions similarly to the GM SPS client. By itself, DPS can only perform the basic function of reading the ECU VIN and basic information. To program a module using DPS, you must acquire the corresponding calibration files and custom DPS scripts to complete any DPS programming. Only limited information, and no complete documentation, is available to the public on using DPS. All the information posted on this website about DPS was developed over time through a routine trial-and-error process. Note: You must have …

Hello, I have DTC error B0158 on instrument cluster. Symptom:05 Description: Ambient Air Temperature Sensor Circuit. It appeared after I replaced old IPC with new one from 2017 Camaro. Now on media display ambient air temperature is not displayed, there are only two minuses and sometimes correct temperature flashes and disapears. Has anyone idea if there is solution for this? Thanks a lot

Hello everyone, I am working on a full retrofit project for my Onix Joy and am looking for technical support regarding the calibration files (.bin/.vbf) to avoid manual HxD editing and minimize bricking risks. 1. BCM (K9) – Objectives and Data VIN: 9BGKL48U0KB211648 Part Number: 52119531 Features to enable: Trunk release (Remote + Physical actuator). Dimmer control (Rheostat via CAN). Light miles Need: I am looking for the original GM calibration files for these functions. I am aware these are not just isolated bits and bytes, and flashing via GM DPS would be the safest route. 2. IPC (Instrument Cluster) Swap Upgrade: Joy → Activ. Donor Cluster: VIN 9BGKC48V0KG244533. Nee…

Hey, I have the following problem. I'm trying to retrofit the Bose amplifier on an I06. Bose amplifier 39136620 Silver box 39132631 Connected to the MOSt ring, with GMLAN and MOST enabled. The MOST ring is also closed—at least the IPC, the HMI, and the radio are working. However, when the source is the HMI, I get a brief audio dropout every second. On my desk, I can access the Bose amplifier via VXDiag. In the car, though, I can’t. GMLAN is definitely connected. Pro

Hello everyone, I need to activate UJM on my 2011 Astra. I have a multi-line dashboard 13442459 installed, but unfortunately I don't have the correct calibrations for this dashboard. However, I have tried to edit calibration number 5 using the same method as with other dashboards. I have added a tire pressure tab, but the manual learning menu doesn't appear. I have also edited calibration 3 of the BCM, but I haven't been able to learn the sensors, even using diagnostic software. Then I tried to completely flash all the calibrations from the astra j gtc with the ujm option. And I was able to start the learning through gds2, but although the sensors were attached and showed…

Hi everyone, I’m curious if anyone here has successfully retrofitted or enabled the OEM Remote Start function on a GM/Opel vehicle that originally didn’t come with it from factory. I’d like to know: Which vehicle/platform did you do it on? What hardware was required (BCM, key fobs, etc.)? Any immobilizer / security challenges? What was the procedure for doing this? (step by step) Thanks in advance for sharing your setups and lessons learned.
