fuse fuse
Voltage of battery → fuse FB29 → fuse FB15 ： one line supplies to the K15 pin of
Circuit of the Front Engine Compartment Fuse Box → supply power to EMS ； another line
supply to EMS Relay → EM S ， when the EMS Relay coil get electricity ， the contact
p oint close ， voltage of battery → fuse FB29 → fuse SB1 → EMS Relay contact point, and
then the power supply is as f ollow:
② FB3 → the L10 pin of Circuit of the F ront En gine Co mpartme nt Fuse
B ox → Inst rument/ ISU/DL C 。
③ F Fb1 → the K7 p in of Circuit of the Front Engine Compartment Fus e Box →
ABS Mod ule 。
④ F FB2 → the L19 pin of Circuit of the F ront En gine Co mpartme nt Fuse
B ox → Power Rear View M irror 。
⑤ F FB5 → the K8 p in of Cir cuit of the Front Engine C ompartment Fuse Box →
EMS 。
⑥ F FB7 → the G20 pin of Circuit of the F ront En gine Co mpartment Fuse
B ox → Air Conditioner 。
（ 3 ） The 50 th line Ignition s witch → t he G13 pin of Circuit of the Fron t Engine
Compartment Fuse Box → Starter Relay coil get electricity ：
Voltage of battery → FB29 → SB2 → Starter Relay contact poin t-the J8
p in of Cir cuit of th e Front Engine Compartment Fuse Box → Starter
9 ．
① fuse FB8 → the K18 pin of Circuit of the Front Engine Compartment Fuse Box →
Front Oxygen Sensor Warmer 。
② fuse FB9 → the K17 pin of Circuit of the Front Engine Compartment Fuse
Box → Rear Oxygen Sensor Warmer 。
③ The J10 p in of Circuit of the Front Engine Compartment Fuse Box → EMS 。
④ The J9 pi n of Circu it of the Front En gine Compartmen t Fuse Box → Electronic
Fan
⑤ Fuel Pump Relay → the K1 0 pin of Circuit of the Front Engine Compartment
Fuse Box → EMS. When Fu el Pump Relay get electricity ， the contact point cl ose ，
voltage of battery → fuse FB29 → fuse FB16 → Fuel Pump Rel ay contact → the C7 pin
of Circuit of the Front Engine Comp artment Fuse Box → Fuel Pump
⑥ A/C Clutch Relay → the K9 pin of Circuit of the Fron t Engine Compartment
Fuse Box → EMS.When A/ C Clutch Relay get electricity ， th e contact point cl ose ，
voltage of battery → fuse Fb29 → fuse FB20 → A/C Clutch Relay contact → the P8 pin
of Circuit of the Front Engine Comp artment Fuse Box → Air Conditioner Clutch
