Disconnect the solenoid connector. C Measure resistance between the solenoid connector and solenoid body. OK Resistance: 10 — 16 . C Connect positive × lead to terminal of solenoid connector, negative ⊕ lead to solenoid body. OK The solenoid makes an operating noise. Mechanical Check P 1. Remove the oil pan. 2. Remove the No.1 and No.2 solenoid valves. C 1. Applying 490 kPa (5 kgf/cm², 71 psi) of compressed air, check that the solenoid valves do not leak air. 2. When battery positive voltage is supplied to the solenoid valves, check that the solenoid valves open. AT5530 AT5531 AT5628 Air Battery OK NG Replace solenoid valve. 2 Check harness and connector between ECM and solenoid (See page IN–30). OK NG Repair or replace harness or connector.
