Hello everyone,
I’m trying to retrofit dTPMS on my 2019 XC90 T6 Inscription (Middle East / GCC spec) with Keyless Entry for all 4 doors. The car originally came with indirect TPMS (iTPMS) from the factory. I feel like I’ve hit a brick wall and could really use your expertise.
Hardware Setup:
I purchased Autel MX-Sensors (1-Sensor) and had a tire shop program them using an Autel tool. To make sure everything matches perfectly, they specifically programmed the sensors to match the "Recommended PN" shown in the OrBit Config Wizard, which is 31362304. The exact OEM file used on the Autel tool was Volvo -> XC90(EU) 2015/01-2022/12 (433MHz 31362304). They were installed and triggered properly.
OrBit CCF Changes:
I changed the following parameters:
[267] INDIRECT TPMS SYSTEM: 01 WITHOUT INDIRECT TYRE PRESSURE MONITORING SYSTEM
[019] TYRE PRESSURE MONITORING SYSTEM: Tried 05 TPMS WBL EU ALGORITHM (also tested 03 US ALGORITHM, and even WBA variants just in case).
[020] TPMS MENU FUNCTIONS: 08 WITH TPMS MENU, SHUT OFF/SHOW PRESSURE/RESET
The Issue:
After applying the CCF and doing a Module Reset for the CEM, IHU, and VCM, the new dTPMS UI appears on the Sensus screen. However, the "Calibrate" button is completely greyed out and unclickable. I drove the car at highway speeds (80-90 km/h) for over 20 minutes, but nothing changed.
Troubleshooting Done:
I completely reverted the CCF to factory (indirect), reset all modules, and then re-applied the dTPMS retrofit settings from scratch. Still greyed out.
I tried manually writing the Sensor IDs to the CEM to force the system to read them. I went to ECU Tools -> CEM -> 2812 TPMS Pre-learnt Wheel Unit IDs. I converted my Autel sensor IDs to Hex format.
With the car in Ignition Position II (engine off), every time I try to send the command, OrBit rejects it and returns:
Error Reason: Request out of range
Since the Calibrate button remains greyed out and the manual ID entry is blocked, I have two questions:
Has anyone experienced the greyed-out Calibrate button even with the exact matched PN?
Does this mean my ME-spec XC90 is physically missing the 433MHz TPMS receiver hardware (is it omitted from the RKE module in GCC specs?), or am I missing a specific step/parameter to wake up the system?
Any insights would be greatly appreciated!
