What Does This Indicator Mean?
The Jetour Yellow Adaptive Cruise Control ACC Error Light indicates that the vehicle’s advanced driver assistance system has detected a fault, calibration drift, or communication failure within its primary radar, LiDAR, or optical camera network. Specifically engineered for Jetour models such as the X70 and X90 series, the adaptive cruise control subsystem relies heavily on a front bumper-mounted radar transceiver and a windshield-mounted multi-purpose camera module. When the Powertrain Control Module (PCM) or the Advanced Driver Assistance System (ADAS) gateway control unit registers obstructed signals, corrupted CAN bus data packets, or voltage anomalies from these sensors, it triggers this yellow warning light to alert the operator that automated speed regulation and distance-keeping features are temporarily disabled.
Can I Still Drive with This Light On?
Yes, you can still drive the vehicle, but with significant operational limitations. Because the severity color rating is yellow, this indicates a non-critical advisory fault rather than an immediate powertrain or catastrophic braking failure. The standard mechanical braking, steering, and engine throttle functions remain fully operational under direct manual driver control. However, your Adaptive Cruise Control, Forward Collision Warning (FCW), and potentially Automatic Emergency Braking (AEB) systems will be completely deactivated. Do not rely on the vehicle to maintain distance from traffic ahead, and exercise heightened manual driving vigilance until the system is properly diagnosed and repaired.
Common Causes of the Warning
- Radar and Camera Obstruction: Accumulated mud, heavy snow, ice, stubborn insect residue, or an improper vinyl wrap directly over the front bumper radar module or upper windshield camera zone blocks the line of sight required for proper sensor operation.
- Sensor Misalignment: Minor front-end collisions, parking lot bumps, or chassis vibrations can physically shift the radar bracket or optical camera alignment outside of allowable factory calibration tolerances.
- CAN Bus Communication Faults: Electrical resistance anomalies, water intrusion in harness connectors, or corrupted data packets traveling along the Controller Area Network bus can interrupt the continuous signal exchange between the ADAS module and the Engine Control Module.
How to Diagnose and Reset It
Begin your diagnostic procedure by thoroughly inspecting the exterior front bumper fascia and the interior upper windshield glass surrounding the rear-view mirror to ensure the sensor lenses are completely clean and free of debris. Next, use an advanced OBD2 diagnostic scanner capable of reading manufacturer-specific chassis and body control modules (C and U codes) to query the ADAS or radar control unit for active fault codes. Inspect the wiring harness and electrical connector plugged into the back of the front radar unit for signs of corrosion, bent pins, or chaffed wires. If no physical damage or obstruction is present, the warning light may require a professional static or dynamic sensor recalibration performed using specialized Jetour diagnostic software at a certified service center. Once the root mechanical or electrical cause is resolved, clear the diagnostic trouble codes through the scan tool to reset the dashboard indicator.
