DI - 220 Diagnosis - Diagnosis-fault diagnosis of electronic and electrical parts

d. Take a multimeter voltage gear to measure the voltage
between No.2 terminal of the left front grouped lamp
connector B004 and grounding, and the voltage between
No.2 terminal of the right front grouped lamp connector
B070 and grounding.
Standard voltage:

Multimeter connecting terminal Standard value

B004(2)-grounding Storage battery voltage

B070(2)-grounding Storage battery voltage

Check if the result is ok?
Yes>go to Step 5.
NO>repair or replace the open harness between the low beam lamp relay to left front combination lamp

5. Check the light combination switch
a. Ignition switch:LOCK.

b. Disconnect the connector B034 of light combination switch
c. Light combination switch is set to "low beam" gear.

d. Take a multimeter resistance gear to measure the
continuity between the No. 2 and No. 4 terminals of the
light combination switch connector B034.
Standard resistance:
Multimeter connecting terminal Standard value

B034(2)-B034(3) Conduction

Check if the result is ok?
Yes>go to Step 6.

NO>replace the light combination switch
6. Check ground circuit of low beam

a. Ignition switch:LOCK.
b. Disconnect the connector B004 of left front combination lamp and the connector B070 of right front
combination lamp
