Check idle adjustment screw for seizure. Start engine. Adjust ignition timing with "WORK SUPPORT" showing on display. Check to ensure engine is set to specified idle speed using idle adjustment screw. Idle speed: M/T 650 ± 50 rpm; N.CVT 750 ± 50 rpm; M/T + L.S.D. 750 ± 50 rpm; M/T (for North Europe) 750 ± 50 rpm; M/T + L.S.D. (for North Europe) 850 ± 50 rpm. (Place select lever in "N" on N.CVT models during idle adjustment.) (Without CONSULT: Start engine. Disconnect throttle sensor. Check to ensure engine is set to specified idle speed using idle adjustment screw. Idle speed: M/T 650 ± 50 rpm; N.CVT 750 ± 50 rpm; M/T + L.S.D. 750 ± 50 rpm; M/T (for North Europe) 750 ± 50 rpm; M/T + L.S.D. (for North Europe) 850 ± 50 rpm.)
N.G.
Check A.A.C. valve and throttle valve for seizure.

Check compression pressure. Standard value: 1,324 kPa (13.24 bar, 13.5 kg/cm2, 192 psi)/350 rpm. Minimum: 1,128 kPa (11.28 bar, 11.5 kg/cm2, 164 psi)/350 rpm. Pressure difference tolerance among cylinders: 98 kPa (0.98 bar, 1.0 kg/cm2, 14 psi)/350 rpm.
N.G.
Check piston, piston rings, valves, valve seats and cylinder head gasket.

Check E.C.U. harness connector. Check E.C.U pin terminals and harness connector for poor contact or damage.
N.G.
Repair or replace.
