I scanned my truck and code C1340 Anti-Lock Braking System popped up. Open circuit in center differential lock signal (during center differential lock ON). This has caused no issues other than that I cannot engage 4hi or 4lo. When I try to engage either, my 4hi light flashes. All of my ABS wires appear to be intact. Any ideas of what I should do?
