Symptoms
- The affected function (lighting, locking, windows, seats, climate or restraint) does not work or works intermittently
- Warning light or message on the instrument cluster
- Possible battery drain if a module stays awake
Common causes
- Blown fuse or no power supply to the No Communication to VICS Module (No Fitting of VICS)
- Poor ground for the module
- Damaged CAN/data bus wiring or connector
- Failed module
- Low battery voltage during cranking or after a jump start
How to diagnose
- Check which modules respond to a full system scan and which do not
- Verify fuses, power and ground at the No Communication to VICS Module (No Fitting of VICS) connector
- Measure CAN bus resistance between the two bus wires (about 60 ohms with the battery disconnected) and inspect the wiring
- Check battery voltage and charging system; low voltage causes many communication codes
- Replace or reprogram the module only after power, ground and bus wiring are confirmed
Frequently asked questions
Can I keep driving with B2202?
Yes. The fault does not affect safety or driveability, but it will keep the warning light on and may fail an inspection.
Will clearing B2202 fix it?
No. Clearing only erases the stored code; it returns as soon as the monitor runs again unless the cause is repaired.
