No. An open circuit means the pump never runs. Without lubrication/cooling flow inside the transfer case, internal bearings and clutches will fail catastrophically ($3,000–$5,000 repair). Pro Tip from the Shop "I've seen 10 P1889-13 codes in the last year. Six were just the connector corroded from a leaking transfer case output seal. Always check the connector first. Don't sell a pump until you've probed it." Related Codes: P1889-14 (short to ground), P1889-11 (short to power), P1889-64 (signal plausibility error). This code relates to the motor circuit
