2.CHECK HARNESS (OPEN CIRCUIT). Using a tester, measure the resistance between the PRG CM connector and PRG auto closer connector. Connector & terminal (R423) No. 2 — (D153) No. 1: (R423) No. 3 — (D153) No. 2: (R422) No. 9 — (D153) No. 4:	Is the resistance less than 10 --	Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC B2526 AUTO CLOSER MOTOR CIRCUIT OPEN	Repair or replace the open circuit of harness.
3.CHECK HARNESS (GROUND SHORT CIRCUIT). Using a tester, measure the resistance between the PRG CM connector and chassis ground. Connector & terminal (R423) No. 2 — Chassis ground: (R423) No. 3 — Chassis ground:	Is the resistance 1 M- or more-	Replace the PRG CM.
