2) Check to make sure that fast idle cam and cam follower lever are not in contact with each other. If they are, check fast idle control system.
3) Loosen TP sensor screws.
4) When SUZUKI scan tool and cartridge are available, set them to DLC with ignition switch OFF.

0.50 ± 0.15 V

Tightening torque
TP sensor screw (a): 2.5 Nm (0.25 kgf-m, 1.8 lbf-ft)

6) Check to make sure that TP sensor voltage is specified value when throttle is fully open.

TP sensor voltage when throttle is fully open
4.0 ± 0.5 V

7) Install ECM if removed.
8) With ignition switch OFF, disconnect battery negative cable from battery for 5 minutes or more.
