DI - 230 Diagnosis - Diagnosis-fault diagnosis of electronic and electrical parts

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

B034(2)-B034(4) No breakdown

Check if the result is ok?
Yes>go to Step 3.
NO>replace the light combination switch

3. Check the low beam harness short-to-power
a. Ignition switch:LOCK.

b. Disconnect the connector B004 of left front combination lamp
c. Disconnect the connector B070 of right front combination lamp

d. Light combination switch is set to "low beam" gear, the ignition switch: ON.
e. Take a multimeter voltage gear to measure the voltage
between No.2 terminal of B004 and grounding, and the
voltage between No.2 terminal of B070 and grounding.
Standard voltage:

Multimeter connecting terminal Standard value

B004(2)-grounding 0V

B070(2)-grounding 0V

Check if the result is ok?
Yes> Repair or replace the harness of the low beam power supply short to power.
NO>retest the above steps
