Repair the open circuit fault between the terminal No. 1 the brake lamp switch wire
harness connector IP56 and the fuse IF03.

(a) Make sure that open-circuit fault between brake lamp switch wire harness connector IP56

terminal No. 1 and fuse IF03 is repaired.

Confirm whether the brake lamp works normally.

7 Check

brake

switch

(a) Disconnect brake lamp switch harness connector, stepped down brake pedal, measure

resistance between brake switch terminal No. 1 and 2

Standard Resistance: less than 1 Ω

Confirm if the resistance conforms to standard value.

8

Inspect the circuit between the brake lamp switch wire harness connector IP56 and the
terminal No. 1 of the brake lamp wire harness connector SO31/24/46.

(a) Disconnect harness connector SO31, SO24, SO46.

(b) Measure resistance value between Brake lamp switch harness connector IP56 terminal No. 2

and rear combination harness connector SO31/24 terminal No.1.

(c) Measure resistance between brake lamp switch harness connector IP56 terminal No. 2 and

high mounted brake lamp harness SO46 terminal

Standard Resistance: less than 1 Ω

Confirm if the resistance conforms to standard value.

9

Inspect the circuit among the combination lamp wire harness connectors SO31/24 and
SO46 and the body grounding.

Overhaul fuseIF27 circuit

(a) Check short circuit of fuse IF27 circuit

(b) Repair the circuits. Confirm that there are no short circuits.

(c) Replace the fuses with rated current.

Confirm whether the reverse lamps are working properly.

5

Measure the voltage of terminal No. 1 of the harness connector EN22 of the reverse gear
switch.

(a) Use multimeter to measure

terminal voltage of reversing
lamp switch wire harness
connector EN22 terminal.

Standard voltage: 11-14 V
