INSPECTION

PROCEDURE

1. INSPECT EV DRIVE MODE SWITCH (COMBINATION 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

I61-8 (S) - I61-5 (E)

EV drive mode switch (combination switch assembly) being pushed and held

Below 50 Ω

EV drive mode switch (combination switch assembly) not pushed

10 kΩ or higher

If the result is not as specified, replace the EV drive mode switch (combination switch assembly).

*a

Component without harness connected

(EV Drive Mode Switch (Combination Switch Assembly))

(b) Check illumination.

(1) Apply auxiliary battery voltage between the terminals of the switch, and check the illumination condition of the EV drive mode switch (combination switch assembly).

Standard:

Measurement Condition

Specified Condition

Auxiliary battery positive (+) → I61-4 (ILL+)

Auxiliary battery negative (-) → I61-1 (ILL-)

Illuminates

If the result is not as specified, replace the EV drive mode switch (combination switch assembly).
