SERVICE:
#1. If SWDL fails and HLCM is in “Not responding”, it is normal. HLCM is in silent mode and
therefore not listening to diagnostic commands.
Continue with the next SWDL attempt without any action.
#2. If SWDL fails due to Silent mode (picture VIDA1_EX90), follow this:
*• Check if HLCM is in fail safe mode under “Components” - “High- to Low-voltage Converter
Module (HLCM)” - “Diagnostic Sequences” - “Recovering HLCM from fail save mode”
•
Check VIUP (PGWM and PGWA) is in Default. If not, follow “Recover VIUP/D failed
SWDL” under point #3 below.
•
Check that HVBM is in Default.
a. If it is not in Default, perform a 12V reset with VIDA for more than 10 minutes.
b. If it is in Programming, perform a reload of HVBM.
•
Check that HVB SOC is above 2%. If not, charge the HVB.
*• If all of the above is okay and SWDL still fails due to Silent mode, open the VIDA diagnostic
sequence under “Service Functions” - “Disconnect Main Battery” and deactivate and
activate HLCM converting and try again.
If the issue still remains, contact RTS through a Support Needed vehicle report in TIE.
#3. If SWDL failed due to the VIUP/D being partly installed (picture VIDA2_EX90), follow this:
Check if VIUP/D is in Programming or Not responding.
a. If VIUP/D is in Programming:
aa. Perform a 12V reset with VIDA diagnostic sequence under “Service Function” “Disconnect Main Battery”, 30 minutes.
ab. Reload VIUP/D.
b. If VIUP/D is not responding:
ba. Perform a 12V reset with VIDA diagnostic sequence under “Service Function” “Disconnect Main Battery”, 30 minutes. (try at least 3 times).
bb. If we get VIUP/D in Programming, perform a reload.
bc. If VIUP/D is still in not responding, contact RTS through a Support Needed vehicle
report in TIE.
•
How to do a 12V hard reset if 12V reset with VIDA fails (step #2 & #3):
Alt a:
a1. Disconnect 12V batteries.
a2. VIDA => Software installation => Advanced test => Reset
*a3. Connect 12V batteries after more than 10 minutes. Ensure the main (rear) battery is
connected first. It is crucial to wait at least 30 seconds before mounting the redundant
(front) battery.
Alt b:
b1. Disconnect 12V batteries.
b2. Access the VCU in the front passenger compartment and disconnect connector (see
picture VCU1) on the VCU for more than 10 seconds.
*b3. Connect 12V batteries after more than 10 minutes. Ensure the main (rear) battery is
connected first. It is crucial to wait at least 30 seconds before mounting the redundant
(front) battery.

#4. If there is a VIDA message “Purchase Failed - StatusCode: 502 ServerCode: 10” (picture
VIDA3_EX90)
Contact RTS through a Support Needed vehicle report in TIE.
#5 Pairing of key tag:
a. Charge the key tag on the WPC.
If not charging, follow TJ 37030.
b. Pairing of key tag fails:
Car needs to be in status Available or higher => close and reopen driver door.
*Make sure that WPC is active and charging the key tag.
c. Pairing of key tag fails:
If you get message in VIDA, “...potential issue between key and Wireless Phone Charger...”
(picture WPC), perform a TCAM reload, “Yes” to replace hardware.
Then retry pairing.
d. Key tag pairing may be lost after SW download.
Check key tag pairing by removing the NFC card from the car, enter the car with the key tag
and check if it’s possible to put car in D or R.
If message “No Key found” appears - pairing is required via “Keyless vehicle key Appl” SWDL.
#6. PDS upgrade yellow message – not complete!
After PDS is done with yellow message “..SW installed needs verification..” (picture VIDA Yellow
message), perform the following steps:
1. Click “OK” or “Cancel” on the error message.
2. Revoke the software.
3. Re-download the PDS.
Check key tag pairing again.
#7. General VIDA warning messages:
a. General VIDA warning messages, example “no response HUD” (picture HUD) after PDS
upgrade:
If the warning message appears after PDS installation, please perform a reset of vehicle
under Advanced Test Option in VIDA and check if the ECU is in Default, if not repeat this
step 2 more times.
If problems still occur, contact RTS through a Support Needed vehicle report in TIE.
b. General VIDA warning message, example “Critical failure” (picture VIDA4_EX90)
If the warning message appears in the beginning of PDS installation follow below:
If usage mode is “Convenience” make sure that no one is seated in the car and try again.
If the problem still exists, turn off climate in CSD.
If problems still occur, contact RTS through a Support Needed vehicle report in TIE.
#8. If a vehicle readout is done and some nodes are Not Responding follow the steps below:
a. Generic method.
Perform reset 3 times under VIDA => Software installation => Advanced test => Reset.
If 3rd reset doesn’t set the ECUs to Default or Extended, then run VIDA “Service Function”
- “Disconnect Main Battery”.
If problems still occur, contact RTS through a Support Needed vehicle report in TIE.
