Complete Guide for ACURA TLX 2015-2020 Electronic Fan Testing with HDS Diagnostic Instrument
preparation
I. Device connection:
Connect the HDS diagnostic instrument to the vehicle via the 16 pin OBD-II interface (located under the driver's dashboard)
Ensure that the ignition switch is in the ON position (the engine can be turned off)
Use wired connection to ensure signal stability
II. Environmental Inspection:
Ensure good ventilation in the engine compartment
Check that the coolant level is between MIN-MAX
Remove debris around the electronic fan
III. Software startup:
Start the HDS software and select the "2015-2020 ACURA TLX" model
Enter the "Engine Control System" module
Detailed explanation of testing steps
Step 1: Enter the electronic fan test menu
1. Select "Special Features" from the main menu
2. Select the "Electronic Fan Test" submenu
3. The system will display the following test mode options:
|
Test mode |
Function Description |
Applicable scenarios |
|
Low speed mode (30% duty cycle) |
Activate the electronic fan to run at low speed (about 1500rpm) |
Check the low-speed circuit and relay function |
|
High speed mode (70% duty cycle) |
Activate the electronic fan to run at high speed (approximately 2500rpm) |
Check the high-speed circuit and relay function |
|
Air conditioning linkage mode |
Simulate fan operation under high pressure of air conditioning |
Check the linkage function of the air conditioning system |
Step 2: Conduct testing
1. Confirm execution after selecting the desired testing mode
2. Observe the actual operation of the electronic fan:
Start response time (normally within 2 seconds)
Smooth operation (no abnormal vibration or noise)
Speed stability (no significant fluctuations)
3. Use HDS data stream function to monitor:
Fan control signal voltage (normal range 12-14V)
Duty cycle of PWM signal output by ECU (should match the selected mode)
Related temperature sensor data (to ensure normal system temperature)
Testing precautions
Security Warning:
Do not place your hands or tools near the rotating fan blades during testing
Avoid prolonged testing in high temperature environments to prevent overheating
If any abnormalities are found during the testing process, they should be stopped immediately
Key points for electrical inspection:
Confirm that the main fuse (40A) is intact before testing
The resistance of the relay coil should be within the range of 60-120 Ω
Measure the control signal from the ECU to the relay, which should be 12V when the ignition is turned on
System status monitoring:
Pay attention to the water temperature indicator on the dashboard
If the water temperature exceeds 105 ° C, the test should be stopped immediately
After testing, wait for the system to cool down before proceeding with other operations
Repair suggestions
Accessory replacement:
Use original fan motor to ensure resistance parameter matching
Ensure the correct position of the rubber shock absorber pad during installation
The wiring harness should avoid high temperature areas
Maintenance cycle:
Clean the dust accumulation on the fan blades every 2 years
Check the motor bearing clearance every 3 years
Test the high and low speed functions before summer every year
