JAC T6 owners often report sudden warning lights such as the check-engine light, ABS light, o r traction control light. The causes are typically related to sensitive sensors o r electrical inconsistencies.

Common Causes

Sensitive o r Low-Quality Sensors:
Some sensors O2 sensor, ABS sensor, MAF sensor are sensitive and can trigger warnings due to minor faults o r dirt buildup.

Weak Electrical Wiring o r Connectors:
Loose plugs, poor connectors, o r wiring exposed to moisture can create false sensor readings.

Battery & Voltage Issues:
A weak battery o r unstable voltage can trigger random dashboard warnings.

ECU Calibration Problems:
The ECU on some units is very sensitive and may flash warnings over small irregularities.

Dirty Air Intake Components:
Dusty conditions cause the MAF sensor and throttle body to get dirty quickly, triggering check-engine lights.

ABS Sensor Exposure:
Because the pickup is often used on rough roads, mud and stones can damage o r block the ABS sensor.

Possible Solutions

Clean the MAF sensor and throttle body regularly

Ensure battery voltage is stable and terminals are tight

Check wheel sensors for mud, damage, o r loose connections

Use a scanner to read codes instead of guessing the problem

Seal o r secure wiring connectors that are exposed to water o r dust

Perform periodic ECU resets after repairs

Proper diagnosis with an OBD scanner often solves these issues quickly.
