This bulletin is to announce the opening of the Kelsey Hayes Technical Assistance Center (K-TAC). K-TAC will provide diagnostic and repair assistance on 4WAURWAL vehicles, and parts shipping (4WAL only) of the brake pressure modulator valve (BPMV), formerly called the electro-hydraulic control unit (EHCU).
FOR 4WAL, AN AUTHORIZATION CASE NUMBER FROM K-TAC IS REQUIRED BEFORE ANY BPMV (EHCU) WILL BE SHIPPED. ALL BPMVs WILL BE SHIPPED OVERNIGHT AND WILL BE INVOICED TO DEALERS VIA GM PARTS (GMSPO). A CORE CHARGE WILL BE INVOLVED. ALSO, INITIAL SHIPMENTS WILL NOT CONTAIN THE NECESSARY RETURN SHIPPING MATERIALS. THEY WILL BE PACKAGED SEPARATELY AND SENT THROUGH NORMAL GMSPO CHANNELS.
For RWAL, call K-TAC for diagnostic and repair assistance, but no parts authorization will be provided.
