Hi All,
I have read almost all thread of seat retrofit, but unfurtunatly I ran into the wall. Short background:
I wanted to swap on 17 XC90 US version car with Momentum seats (Front Driver/Passenger heated) to Inscription (Heated + Ventilation + Side support + Massage).
Front seats:
What I did:
1. Wired positive wire from fuse box (#40) to each seat connector 15PIN.
2. Switched wire between seats on PSMD and PSMP wired 21PIN ground (Inscription seats were taken from right hand car);
3 Made configuration on Orbit:
179 Front seat ventilation > Enabled driver and passenger
180 Heated front seats > Enabled (It was already set up)
239 Massage front seat > Enabled
240 Lumbar support > 4 ways
241 Cushion Extension > Enabled Driver and passenger
243 Power Adjustable side support > Enabled driver and passenger
462 Heating Mat variants > Enabled cushion and backrest
244 Remote passenger seat control > Enabled
Additionally:
127 Seat Track sensor > Disabled. (Momentum seats (left/Right) had sensors; Inscription - no sensors on seats).
4. After programing made ECU reset. Closed and locked car for 5-10 minutes.
After doing this, I ran DTC and here I had faults:
PSMD:
U2300 - Central configuration - System programming failures - Invalid/ incompatible configuration;
SRS:
B00115 - Driver seat track position restraints sensor - general electrical failures - circuit opened.
B00125 - Passenger seat track position restraints sensor - general electrical failures - circuit opened.
Additionally, then I am moving seats via buttons on IHU I see different view between Driver and Passenger seat of possible functions (Added photo). Driver seats looks good, 4 features can be done (massage, Lumbar, side support, Cushion Extension). But on Passenger seat IHU shows only 3 options (Massage function, Lumbar support, Side support), missing Cushion extension option. However, if I go with button on seat down (thinking its same way control as driver seat), I can move on passenger seat cushion extension, but on IHU nothing is showing.
My concerns:
1. How to Deactivate driver/Passenger seat track sensors?
2. What configurations are made incorrect, that PSMD shows configuration fault?
3. What configurations should be made, that IHU will be showed cushion extension feature on passenger seat?
