• Preventive maintenance works: regular fluid checks and following the service interval keep the all-wheel drive system healthy and the warning lights off.
• Reset the light correctly: clear the codes with a scanner, then drive to verify the repair. If the light returns, the root cause is still present.
• When in doubt, seek help: complex issues like a failed ABS module or wiring harness damage are best handled by a qualified technician.

Why the 2017 Journey AWD Service Light and Traction Control Light On?

When both the AWD service light and the traction control light turn on, it means the vehicle’s computer has detected a fault. The 2017 Journey AWD service light and traction control light on alert is designed to protect you, but it doesn’t always mean a catastrophic failure. Often, it’s a minor sensor issue that can be fixed in an afternoon.

What Each Light Means

The AWD service light looks like a car with skid marks. It indicates a problem with the all-wheel drive system. The traction control light shows a car sliding. It means the system that prevents wheel spin is disabled. When both are on, the vehicle may still drive, but you lose some stability features.

Common Triggers for Both Lights

Several things can cause both lights to appear at once:

• A faulty wheel speed sensor
• Low transmission fluid
• A bad ABS module
• Wiring issues in the rear axle
• An electronic stability control fault
• A failed transfer case motor

Each of these triggers sends a trouble code to the engine control module. The module then turns on both lights to warn you.

Step-by-Step Diagnosis: Finding the Root Cause

Before you replace parts, you need to know the exact cause. A proper diagnosis saves time and money. Here’s how to find the root cause of the 2017 Journey AWD service light and traction control light on condition.

Using an OBD-II Scanner

Plug an OBD-II scanner into the port under the steering column. Turn the key to the “On” position without starting the engine. Read the diagnostic trouble codes (DTCs). Write down every code. Common codes for this issue include C0035 (left front wheel speed sensor), C0040 (right front), and U0100 (lost communication with ECM).

Quick Tips: If you don’t have a scanner, many auto parts stores will read codes for free. Write them down exactly as they appear.

Checking the ABS Wheel Speed Sensors

The wheel speed sensors are the most common culprit. They sit near the rear wheels and the front hubs. Over time, they get covered in road grime or the tone ring becomes damaged. A dirty sensor gives a weak signal, which triggers the AWD and traction control lights.

To check them, locate the sensor connector behind the rear wheels. Unplug it and inspect the wiring. Look for frayed wires or corrosion. Use a multimeter to test resistance. A healthy sensor usually reads between 800 and 1200 ohms.

Inspecting the Transfer Case and Rear Differential

The transfer case distributes power to the front and rear axles. If the transfer case motor fails, the AWD system can’t engage. The rear differential also has sensors that can fail. Check the fluid level in both. Dark, burnt-smelling fluid means it’s time for a change. Low fluid can cause erratic behavior and warning lights.

Expert Insights: Many mechanics skip the transfer case fluid check. On the 2017 Journey, the transfer case uses the same fluid as the transmission. If the transmission fluid is low, the transfer case is likely low too.

Top Fixes for the 2017 Journey AWD Service Light

Once you know the cause, you can apply the right fix. Here are the most effective solutions for the 2017 Journey AWD service light and traction control light on problem.

Resetting the Service Light

Sometimes the light stays on even after you fix the issue. You need to reset the service light manually. Use the OBD-II scanner to clear the codes. Then drive the vehicle for a few minutes. If the fault is truly gone, the light will not return. If it comes back, the problem is not fully solved.

Replacing Faulty Wheel Speed Sensors

If the scanner shows a wheel speed sensor code, replace the sensor. The part is affordable, usually under $50. You’ll need a 10mm socket and a wrench. Remove the old sensor, clean the mounting area, and install the new one. Plug the connector back in. Clear the code and test drive.

Fixing Wiring and Electrical Issues

Damaged wiring is a sneaky cause. A rodent might chew a wire near the rear axle. Or a connector might corrode. Inspect all wiring harnesses from the ABS module to the sensors. Repair any broken wires with solder and heat shrink tubing. A loose ground strap can also cause both lights to stay on.

Common Mistakes: Don’t just replace the sensor without checking the wiring. A new sensor won’t fix a broken wire. Always inspect the connector pins for bent or pushed-back pins.

Common Cause	Typical Fix	Cost (Parts Only)	Difficulty
Dirty wheel speed sensor	Clean or replace sensor	$20–$50	Easy
Low transfer case fluid	Top up or change fluid	$30–$60	Easy
Faulty ABS module	Replace or reprogram module	$200–$500	Hard
Wiring harness damage	Repair or replace wires	$15–$100	Medium
Failed transfer case motor	Replace motor	$150–$300	Medium

Traction Control Light On: What Drivers Need to Know

The traction control light on means your vehicle’s traction control system is disabled. This system works with the ABS and electronic stability control to keep the car stable on slippery roads. When the light is on, you lose that extra layer of safety.

How the Traction Control System Works

The system uses wheel speed sensors to detect when a wheel is spinning faster than the others. If it finds one, it applies the brake to that wheel and reduces engine power. This helps the car maintain grip on ice, rain, or gravel. When the light is on, this protection is gone.

When to Drive and When to Stop

If the traction control light is on but the AWD service light is off, you can usually drive carefully to a shop. If both lights are on, avoid highway driving and sharp turns. The car might not respond correctly in an emergency. Have the vehicle towed if you notice any vibration or loss of power.

Quick Tips: In rainy or snowy conditions, drive slowly and leave extra following distance. The traction control system can’t help you if it’s turned off.

Preventive Maintenance to Avoid Future Warning Lights

Regular maintenance keeps the AWD system healthy and prevents the 2017 Journey AWD service light and traction control light on from returning. A few simple habits can save you hundreds of dollars.

Follow the Service Interval

Dodge recommends checking the all-wheel drive system at every oil change. The service light often comes on because the system is due for maintenance. Keeping up with the service schedule resets the light and ensures all components are lubricated.

Fluid Checks and Software Updates

Check the transmission fluid every 30,000 miles. Dark or burnt fluid can damage the transfer case. Also, ask your dealer about software updates for the ABS module. Chrysler has released updates that improve communication between the traction control module and the engine control unit.

Expert Insights: Many owners ignore the service light until it becomes a red flashing light. By then, a minor issue has become a major repair. A simple fluid change at the right interval can prevent this.

Common Mistakes and Expert Insights

Even well-meaning owners make mistakes when the AWD service light comes on. Here are the top errors to avoid, plus expert advice.

Common Mistakes

• Ignoring the light and hoping it goes away
• Replacing parts without reading the diagnostic codes
• Using the wrong fluid in the transfer case
• Clearing codes without fixing the root cause
• Driving aggressively with both lights on

Expert Insights

Experienced technicians say the first thing to check is the rear wheel speed sensors. On the 2017 Journey, these sensors are exposed to road spray and dirt. A simple cleaning with brake cleaner often fixes the issue. If cleaning doesn’t work, replace the sensor. Also, always check the fuse box under the hood. A blown fuse in the ABS circuit can mimic a sensor failure.

Key Takeaways: The AWD service light and traction control light on is usually caused by a sensor or fluid issue. A systematic diagnosis saves money. Regular maintenance prevents most problems.

Conclusion

The 2017 Journey AWD service light and traction control light on can be stressful, but it’s rarely a sign of a total breakdown. Most often, it’s a sensor, a fluid level, or a wiring issue that you can fix yourself. Use an OBD-II scanner to read the codes, inspect the wheel speed sensors, and keep up with fluid changes. If you follow the steps in this guide, you’ll save money and keep your Journey running safely. Don’t wait—tackle the warning lights today and enjoy peace of mind on the road.
