5 Inspect 

EAS 

Coil 

 

(a) Disconnect electronic Anti-theft 

coil harness connector. 

(b) Use multimeter to measure 

resistance of coil. 

Standard Resistance Value: 5 Ω at 
room temperature 20°C(68 ºF) 

Is EAS coil resistance specified value?

Replace electronic Anti-theft coil. 

(a)  Refer to 2.5.8.1 “Replacement of EAS coil” to replace the EAS coil. 

Can the vehicle start? 

 

7 

Inspect circuit between EAS coil harness connector and engine anti-theft system 
control module harness connector. 

(a)  Measure the resistance between the anti-theft coil harness connector IP43 terminal No.2 and 

engine anti-theft system control module wiring harness connector IP25 terminal No.2 with a 
multimeter to determine circuit continuity. 

Standard Resistance: Less than 1 Ω 

(b)  Measure the resistance between the anti-theft coil harness connector IP43 terminal No.5 and 

engine anti-theft system control module wiring harness connector IP25 terminal No.1 with a 
multimeter to determine circuit continuity. 

Standard Resistance: Less than 1 Ω 

Whether resistance meet standard or not?

Repair circuit between EAS coil harness connector and engine anti-theft system 
control module harness connector. 

(a)  Repair the open circuit fault between the electric anti-theft coil wiring harness connector IP43 

terminals No.2 and engine control module wiring harness connector IP25 terminal No.2 to 
determine circuit continuity. 

(b)  Repair the open circuit fault between the electric anti-theft coil wiring harness connector IP43 

terminals No.5 and engine control module wiring harness connector IP25 terminal No.1 to 
determine circuit continuity. 

Can the vehicle start? 

 

9 

Inspect the serial communication circuit between the engine anti-theft system control 
module and engine control module. 

(a)  Inspect the serial communication circuit open between engine anti-theft system control 

module wiring harness connector IP24 terminals No.5 and engine control module harness 
connector EM01 terminal No.46, to determine the continuity. 

Standard Resistance: Less than 1 Ω 

(a)  Inspect the serial communication circuit open between engine anti-theft system control 

module wiring harness connector IP24 terminals No.8 and engine control module harness 
connector EM01 terminal No.75, to determine the continuity. 

Standard Resistance: Less than 1 Ω 

Does the resistance conform to standard value? 

 

10 

Repair serial communication circuit between engine anti-theft system control module 
and engine control module. 

(a)  Repair the serial communication open circuit between engine anti-theft system control 

module connector IP24 terminal No.5 and the engine control module connector EEM01 
terminal No.46. 

(b)  Repair serial communication circuit open resistance between engine anti-theft system control 

module wiring harness connector P24 terminals No.8 and engine control module harness 
connector EM01 terminal No.75. 

Can the vehicle start?
