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

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?

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?
