INSPECTION

PROCEDURE

1. INSPECT ELECTRIC PARKING BRAKE SWITCH ASSEMBLY

(a) Inspect EV mode switch (electric parking brake switch assembly)

(1) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
G24-14 (S) - G24-16 (GND1)	EV mode switch (electric parking brake switch assembly) being pushed and held	Below 1 Ω
G24-14 (S) - G24-16 (GND1)	EV mode switch (electric parking brake switch assembly) not pushed	10 kΩ or higher

If the result is not as specified, replace the EV mode switch (electric parking brake switch assembly).

*a	Component without harness connected (EV Mode Switch (Electric Parking Brake Switch Assembly))

(b) Inspect NORMAL mode switch (electric parking brake switch assembly)

(1) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
G24-13 (B) - G24-16 (GND1)	NORMAL mode switch (electric parking brake switch assembly) being pushed and held	Below 1 Ω
G24-13 (B) - G24-16 (GND1)	NORMAL mode switch (electric parking brake switch assembly) not pushed	10 kΩ or higher

If the result is not as specified, replace the NORMAL mode switch (electric parking brake switch assembly).

*a	Component without harness connected (NORMAL Mode Switch (Electric Parking Brake Switch Assembly))

(1) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
G24-12 (P) - G24-16 (GND1)	SPORT mode switch (electric parking brake switch assembly) being pushed and held	Below 1 Ω
G24-12 (P) - G24-16 (GND1)	SPORT mode switch (electric parking brake switch assembly) not pushed	10 kΩ or higher

If the result is not as specified, replace the SPORT mode switch (electric parking brake switch assembly).

*a	Component without harness connected (SPORT Mode Switch (Electric Parking Brake Switch Assembly))
