The B1000 code on your 2022 Chevrolet Equinox indicates a malfunction with the remote keyless entry (RKE) receiver. This code affects your Equinox's ability to receive signals from your key fob for locking, unlocking, and remote start functions.
Understanding B1000 on Chevrolet Equinox
The RKE receiver is an antenna/module that receives radio frequency signals from your key fob. Code B1000 indicates the body control module has detected a fault with this receiver - it may not be receiving signals, receiving corrupted data, or has lost communication entirely.
Common Symptoms
- Key fob doesn't lock/unlock doors
- Reduced key fob range
- Remote start not working
- Must use key blade or be close to vehicle
- Intermittent key fob response
- One fob works, other doesn't (if receiver works intermittently)
Primary Causes
- RKE receiver module failure
- Antenna damage or disconnection
- Wiring issue to receiver
- Interference from aftermarket device
- BCM communication fault
- Key fob battery issue (less likely if affects all fobs)
Diagnostic Procedure for 2022 Equinox
Try all key fobs - if none work, receiver is likely faulty. Using GM scan tool, access RKE system data. Check if receiver acknowledges fob transmissions. Test receiver antenna if accessible. Look for aftermarket devices that may cause RF interference. Verify wiring to RKE receiver. Check BCM communication with receiver.
Repair Solutions
Replace failed RKE receiver module. Repair damaged antenna or wiring. Remove aftermarket devices causing interference. Reprogram key fobs if needed after receiver replacement. Clear codes and verify reliable fob operation at normal range (typically 30-50 feet).
