c1380 slip error abs warning

[sac602]

My slip error warning light keeps coming on at start, but goes away once I drive (usually within 1-2 minutes). Sometimes the abs also comes on for the same limited time period. I did have a revtec leveling kit installed at 4wparts, so thought maybe abs sensor wire. tested for continuity and both sides (both wires) have same resistance of 1.0-1.1 ohms.

Pulled codes using Carista and BT OBD2 and got c1380, c1422, and c1445. Cleared codes.

C1380 came back along with light. Hoping it is an abs wire or brake sensor, but dont want to start buying stuff needlessly.

also, seems to do it when started, or when in reverse only. moving forward clears the error lights.

TIA
Any ideas before I have to go to the dealer?
(I have searched extensively here and Tacoma forums with limited insight)

Google says ABS code C1380 is an ABS pump fault. If your individual sensors' wiring tests good, then you can probably rule out the individual sensors and replace the pump. I bet ABS pumps are not made by aftermarket manufacturers. You may try eBay or a junkyard - perhaps one off a same generation Tundra?
