Testing the headlight range control switch
1. Remove the switch panel from the instrument panel.
2. Disconnect the 5-pin connector from the switch.
3. Press the switch from behind the panel and remove it.
1. 5-PIN CONNECTOR
2. SWITCH PANEL
3. HEADLIGHT CORRECTION SWITCH
4. Not used
5. Not used
4. Measure the resistance between contacts No.1 and No.3, then measure the resistance between contacts No.3 and No.5 at positions 0, 1, 2 and 3 by moving the handle.
Between contacts #1 and #3: About 4.7 kOhm
Between contacts #3 and #5:
| Handle position | 0 | 1 | 2 | 3 |
| Resistance, kOhm (approximately) | 3,9 | 3,5 | 2,8 | 2,4 |
5. If the resistance is different from the specified value, replace the switch.
1. ELECTRIC HEADLIGHT CORRECTOR UNIT
2. 3-PIN CONNECTOR
3. BLACK AND YELLOW
4. BLACK
5. BLUE-YELLOW
6. Female connector on the harness side
2. Check for continuity between contact #3 (BLACK WIRE) and ground. There should be continuity.
- If there is no conductivity, check:
- Is there a break in the BLACK wire?.
- Poor grounding (G201, G202, G301).
- If there is conductivity, proceed to step 3.
3. Check the voltage between terminal #1 (BLACK/YELLOW WIRE) and ground when the ignition switch is in the ON (II) position. There should be battery voltage.
- If there is no battery voltage, check for a break in the BLACK/YELLOW wire.
- If there is battery voltage, proceed to step 4.
4. Check for continuity between contact #2 (BLUE-YELLOW WIRE) and ground in all switch positions. There should be continuity.
- If there is no conductivity, check:
- If there is conductivity, proceed to step 5.
- Is there a break in the BLUE-YELLOW wire?.
- Is the headlight range control switch working properly?.
- If there is conductivity, proceed to step 5.
5. If all checks show normal, but the electric headlight corrector does not work, check whether the electric headlight corrector unit is frozen, stuck, or installed correctly. If the mechanical part is normal, replace the electric headlight corrector unit.
6. After installation, retest the system.
