Dongfeng 162 protective vehicle - fault and exclude meter electrical failure and exclusion (2)

Coolant is too low alarm light

1. Check whether the liquid level of the anti-rust antifreeze of the expansion tank is too low, which supplements the same model and rust-free antifreeze brand as the specified liquid level, the coolant is too low, and the error is released;

2. If the liquid level is normal, the alarm sensor socket is too low, the cooling liquid is too low, the liquid level is too low alarm sensor damage, replace the liquid level too low alarm sensor, cooling liquid plane excessive alarm is turned off, fault freed;

3. If the liquid level is normal, disconnect the liquid level too low alarm sensor, the coolant is too low, warning is still, internal fault, replacement meter assembly, fault release.

Instrument regulatory lamp is not bright

1. ignition lock \\\"\\\" slide adjustment light switch, instrument background light, air conditioning panel light, etc.

2. Ignition lock in the \\\ slide meter regulating light switch, the instrument background light is not bright, the air conditioning panel light is bright, check if the instrument plug is connected to connect, the line has a broken circuit, repair the fault point, fault release;

3. ignition lock \\\"\\\" slide adjustment light switch, instrument background light, air conditioning panel lighting, etc. Check whether the distribution box 83 # output is normal, if not normal, the central distribution box is damaged, replace the central distribution box, fault release;

4. If the 83 # output is normal, the line breaks through, check the line, fault release;

5. If the central distribution box inductor melt instrument, the oil battery valve is ablated, disconnect the instrument to adjust the lamp switch, if insurance is no longer ablated, check the air-conditioning panel lighting, cigarette lighter, meter background light line, find Short circuit;

6. Disconnect the instrument regulatory light switch, if insurance is still ablation, then check the oil-free battery valve, oil-based battery valve, replace parts damage, repair the fault point, fault release.

Insurance ablation in the central distribution box

1. Check if the fuel tank conversion valve switch is normal, if the fuel tank conversion valve switch is short-circuited, replace the fuel tank conversion valve switch, sequential working fuel tank conversion valve switch, wiper part, central charge, and discharge gas part, if attachment insurance is not After ablation, the fault is released;

2. If the fuel tank conversion valve switch is normal, please check if the windshield is normal, such as annex insurance ablation, disconnection of the windshow squeegee motor, attachment insurance is no longer fusion, remove the windshow squeegee motor to check if the wind window is scraping The server link mechanism is usually operated, if there is pin, paralbial, deformed, etc., adjust or replace the window sweater link mechanism, make it normal, and check if the windshield scraper motor is burning, if you burnt, please replace the window sweater if attachment insurance Failure will be released without ablation;

3. If the fuel tank conversion valve switch is normal, check if the windshield wiper is normal, if the accessory insurance abuses, disconnect the windshow squeegee motor insert, the auxiliary insurance is still ablation, then the window water line beam short circuit, find a short road point, Accessories are no longer ablation, troubleshooting;

4. If the wind window is working properly, check the window cleaning / scraping section, if the window window, the window cleaning motor is inserted, if the attachment insurance is still ablation, it is the windmill motor damage, replace the windows Washing motor, fault freed.

5. If the fuel tank conversion valve switch is normal, the wiper component is normal, check the central filling system, disconnect the electrical pump power supply, the accessory insurance is no longer ablated, the electrical pump part is broken, check whether the electrical air pump is short-circuited or burning, repair Or replace the electrical pump, accessories insurance is no longer ablation, troubleshooting;

6. Disconnect the electrical pump power supply, the accessory insurance is still ablation, check if it is charged, the deflated solenoid valve and charging and the electric pipe have a short road point. Replace the damaged part and repair the short path. The attachment no longer ablates, troubleshooting.
