Mazda rain sensing wipers not working

Spread open the rain sensor cover in the direction of the arrows 1 and disengage tabs A to remove it. Slide rain sensor tabs B in the direction of the arrow 3 shown in the figure, detach the engagement, and pull tab B in the direction of the arrow 4. If the rain sensor is replaced, the auto light system may not operate normally because the auto light sensitivity setting is initialized.

If the rain sensor is replaced, perform the auto light sensitivity setting. If the auto light sensitivity setting before replacing the rain sensor was "Medium", and the following sensitivity setting procedure is not performed, the sensor will be unable to detect the illumination level correctly and the auto light system will not operate normally. If the rain sensor is replaced, perform the following sensitivity setting procedure. If the rate at which the rain sensor reflects or transmits infrared light between the rain sensor and the windshield, or through the protective sheet is changed, the rain sensor will determine that there is a malfunction in the rain detection function and stop auto wiper system control.

Manuals New Top Sitemap Search. Rain Sensor Outline The rain sensor detects the amount of rainfall and calculates the wiper operation speed, and outputs a windshield wiper control signal to the front body control module FBCM to p Other materials: Outer Mirror Glass Installation 1.Using radiator antifreeze as washer fluid is dangerous.

If sprayed on the windshield, it will dirty the windshield, affect your visibility, and could result in an accident. Only use windshield washer fluid mixed with anti-freeze protection in freezing weather conditions:.

Using windshield washer fluid without anti-freeze protection in freezing weather conditions is dangerous as it could freeze on the windshield and block your vision which could cause an accident. In addition, make sure the windshield is sufficiently warmed using the defroster before spraying the washer fluid. Because heavy ice and snow can jam the wiper blades, the wiper motor is protected from motor breakdown, overheating and possible fire by a circuit breaker.

This mechanism will automatically stop operation of the blades, but only for about 5 minutes. If this happens, turn off the wiper switch and park off the right-of-way, and remove the snow and ice. After 5 minutes, turn on the switch and the blades should operate normally. If they do not resume functioning, consult an Authorized Mazda Dealer as soon as possible. Drive to the side of the road and park off the right-ofway.

Set the lever to the intermittent position and choose the interval timing by rotating the ring. From the center position normalrotate the switch downward for higher sensitivity faster response or rotate it upward for less sensitivity slower response.

Otherwise the rain sensor will not operate correctly. Keep hands and scrapers clear of the windshield when the wiper lever is in the AUTO position and the ignition is switched ON as fingers could be pinched or the wipers and wiper blades damaged when the wipers activate automatically.

However, if the wipers cannot remove this ice, dirt or foreign matter, the auto-wiper control will stop operation. In this case, set the wiper lever to the low speed position or high speed position for manual operation, or remove the ice, dirt or foreign matter by hand to restore the auto-wiper operation.

It is recommended that the auto-wiper lever be switched to the position other than when driving the vehicle under rainy conditions. Refer to Personalization Features on. If the washer does not work, inspect the fluid level. If it's normal, consult an Authorized Mazda Dealer. Cargo Compartment Light Inspection 1.

Disconnect the negative battery cable. Remove the cargo compartment light. Verify that the continuity between the cargo compartment light terminals is as indicated in the table.The rain sensor detects the amount of rainfall and calculates the wiper operation speed, and outputs a windshield wiper control signal to the front body control module FBCM to perform automatic wiper operation auto wiper system according to the amount of rainfall.

If the windshield is under any of the following conditions, the rain sensor cannot detect the amount of rainfall correctly and the windshield wipers operate incorrectly. Stickers or labels are adhered to the rain sensor detection area in the upper part of the windshield. The rain sensor emits infrared light from the internal LED, and the infrared light is reflected off the windshield via the lens and received by the photodiode in the rain sensor. If the rate of reflected infrared light is reduced, it is determined that rain is contacting the windshield, and the amount of rainfall is calculated based on the reduction level of the reflection rate.

The calculated amount of rainfall is used for operating the wipers at the optimal speed. When the ignition is switched ON engine off or onthe rain sensor detects and records the transparency of the windshield surface, which varies depending on wear and accumulation of dust.

While the auto wiper is operating, sensitivity of the rain sensor can be optionally adjusted by operating the sensitivity adjustment volume on the wiper and washer switch which changes the volume signal input to the front body control module FBCM.

Sensitivity of the rain sensor can be adjusted between 1 low sensitivity and 5 high sensitivity by operating the sensitivity adjustment volume according to the conditions such as rain intensity.

While the auto wiper is operating, the sensitivity of the rain sensor is adjusted automatically according to the vehicle signal sent from the PCM via the front body control module FBCM. While the auto wiper is operating, the rain sensor auto light sensor detects the illumination level above and in front of the vehicle.

When the rain sensor detects an illumination level higher than a level required for turning on the TNS, the sensitivity of the rain sensor increases. The rain sensor performs on-board diagnostics when the ignition is switched ON engine off or on. If a malfunction is detected in the rain sensor, an error signal is sent to the front body control module FBCM. The infrared light reflected off the windshield is received by the photodiode in the rain sensor.

When the photodiode receives the light, the microcomputer in the rain sensor calculates the rainfall amount from the reflection rate, and sends a windshield wiper control signal to the front body control module FBCM.

Emitted infrared light goes through the windshield and penetrates the rain drops on the windshield. The infrared light which cannot penetrate is reflected off the windshield and is received by the photodiode in the rain sensor.

When the photodiode receives the light, the microcomputer in the rain sensor calculates the rainfall amount from the reflection rate, converts this to an electrical signal and sends a windshield wiper control signal to the front body control module FBCM.

Thread starter Stevespim Start date Dec 1, So, if I set the wipers to the 'auto' setting, are they supposed to stay off until rain hits the sensor at the top of the windscreen? If that's the case, they don't work, they just keep going, as per the interval set under the Auto function.

I've followed the owner's manual and also YouTube videos and set them as instructed, but even in no rain they just keep going. It's worth mentioning that my CX-5 GT is brand new and the windshield is perfectly clean and there are no obstructions over the sensor. This has to be user error. What am I doing wrong? In the info screen under settings, do you have the rain sensing wipers activated or de-activated?
