SYSTEM TEST
Start engine, and warm to operating temperature. Check idle speed. If idle speed is excessive, disconnect IAC valve harness connector. Idle speed should drop. If idle speed does not drop, check IAC valve and related circuits. See DTC P0505: IDLE AIR CONTROL (IAC) in appropriate TESTS W/CODES article.
START SIGNAL SYSTEM TEST
- Turn ignition switch to START position. Measure voltage between ground and ECM harness connector terminal No. 20. See START CIRCUIT WIRE COLOR & ECM TERMINAL IDENTIFICATION table for wire color. (Схема №1) Battery voltage should be present in START position ONLY. Zero volts should be present in any other ignition switch position.
- If voltage is not as specified, check 7.5 amp fuse in fuse block. If fuse is okay, repair circuit between ECM and fuse block. If voltage is as specified, check ECM terminals, harness, and connector terminals for damage or corrosion. Repair as necessary.
