INSPECTION

PROCEDURE

1. INSPECT ELECTRIC PARKING BRAKE SWITCH ASSEMBLY

(a) Check the resistance.

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

Standard Resistance:

Tester Connection	Condition	Specified Condition
7 (SWI1) - 8 (SWO1)	OFF (Release)	100 kΩ or higher
7 (SWI1) - 8 (SWO1)	ON (Lock)	10 Ω or less
7 (SWI1) - 8 (SWO1)	Switch not operated	100 kΩ or higher
7 (SWI1) - 1 (SWI2)	OFF (Release)	10 Ω or less
7 (SWI1) - 1 (SWI2)	ON (Lock)	10 Ω or less
7 (SWI1) - 1 (SWI2)	Switch not operated	100 kΩ or higher
7 (SWI1) - 2 (SWO2)	OFF (Release)	10 Ω or less
7 (SWI1) - 2 (SWO2)	ON (Lock)	100 kΩ or higher
7 (SWI1) - 2 (SWO2)	Switch not operated	10 Ω or less
1 (SWI2) - 8 (SWO1)	OFF (Release)	100 kΩ or higher
1 (SWI2) - 8 (SWO1)	ON (Lock)	10 Ω or less
1 (SWI2) - 8 (SWO1)	Switch not operated	10 Ω or less
1 (SWI2) - 2 (SWO2)	OFF (Release)	10 Ω or less
1 (SWI2) - 2 (SWO2)	ON (Lock)	100 kΩ or higher
1 (SWI2) - 2 (SWO2)	Switch not operated	100 kΩ or higher

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

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

(b) Check the Illumination.

(1) Apply auxiliary battery voltage to the electric parking brake switch assembly and check that the switch illuminates.

OK:

Ignition Circuit

DESCRIPTION A direct ignition system is used on this vehicle. The direct ignition system is a 1 cylinder ignition system which ignites one cylinder with one ignition coil. In the 1 cylinder ignition system, one spark plug is connected to the end of the secondary winding. High voltage is generated in

ECU Power Source Circuit

DESCRIPTION If the ignition switch is ON, the hybrid vehicle control ECU applies current to the MREL terminal to turn the IGCT relay on. This supplies power to the +B1 terminal. WIRING DIAGRAM CAUTION / NOTICE / HINT NOTICE: After the ignition switch is turned off, there may be a waitin
