Thirty-seventh, there is no high-end indicator, can't walk
Cause Analysis:
1, Transfer case The steering cylinder pusher is not adjusted in place;
2, Transfer case There is a fault in the high-end switch;
3, front axis access switch joint welding;
4, long distance control switch or harness plug welding;
5. Long-distance operation control buzzer damage or wire harness joint welding;
6, long distance control control relay damage or model is wrong;
As shown in Figure 7, the air switch is damaged or the circuit is.
8, the clutch switch is damaged or the circuit is not available;
9, five sets of solenoid valve beams fall off;
As shown in FIG. 10, a five-set electromagnetic valve gas path is not available.

Method of exclusion:
1. First check the harness contact of the remote manipulation relay;
2. Check if the control line (blue yellow) on the relay is electric, if no electricity. The description of the clutch switch is damaged or poor contact; if there is electricity, and the other black line is in powerless, indicating the airline switching. Or adverse contact between the line segments;
3. If the blue and black lines on the relay are electricity, green and red dedication headquarters are not electricity, indicating that the relay is damaged;
4. Check if the green line on the remote operation control switch is electricity, if it is not possible, indicating that the filament is damaged or poor contact;
5. If the green line on the switch is powered, the blue line is not electrified, the switch is damaged;
6. If the blue line on the switch is electricity, the buzzer does not ring, indicating the buzzer damage;
7. Check whether the harness on the front bridge is detached;
8. Check whether the wire harness plug on the high-end switch is dropped;
9. Check if the white line on the switch is electricity, if there is no power, Transfer case switch is damaged;
10. Check whether the five-set electromagnetic valve intake pipe is gas or whether the pressure is standard;
11. If the five sets of solenoid valve intake pipes are gases. If the firth firt fulunture is a gas on the five sets of solenoid valves. If there is no gas, check whether the internal coil of the five sets of solenoid valve body is welded. Whether it is welded for each cable;
12. Adjust Transfer case to manipulate the cylinder pusher to the correct position.

Thirty-eight, there is no low-end indication, but the car can drive
Cause Analysis:
1. Low-level indicator light bulb rupture;
2, Transfer case The use of cylinder solenoid valve beam joints fall off or deprive;
3. The right side harness joint of the cab is dropped.
Method of exclusion:
1. Check if the right side harness connector before the cab is dropped;
2, check Transfer case Whether the solenoid valve harness joint is detached or welded in the internal connector of the solenoid valve;
3. Check if the low-level indicator light bulb is burned.
