Loading IAR content
Results are grouped by useful content—not by paid placement or guessed parts. Describe the symptom naturally; IAR recognizes common alternate wording while keeping exact codes and vehicle details precise.
Your available vehicle context is included where the destination supports it. AI guidance stays separate from verified IAR source records.
The lamp may indicate an applied parking brake, low fluid, hydraulic concern, or another vehicle-specific brake-system condition. The symbol alone cannot prove the brakes are safe.
Stop and assessThe anti-lock braking system has reported a fault or has been disabled. Base braking may behave differently, and the exact effect depends on the vehicle and any other warning lamps.
Assess promptlyA pedal that suddenly feels hard or requires much more effort can indicate loss of brake assist, a vacuum/electrical control concern, or another braking fault. Secure the vehicle and verify the exact assist system before driving or replacing parts.
professional recommendedA soft, spongy, low, or sinking pedal can reflect hydraulic leakage or air, master-cylinder or control faults, mechanical adjustment or flex, and other foundation-brake concerns. Braking safety comes before diagnosis.
professional recommendedReduced braking, unusually long stopping, or a vehicle that will not stop normally is a stop-driving condition. Secure the vehicle first, then separate hydraulic, assist, friction, mechanical, and control-system evidence with qualified service information.
professional recommendedUse when and where the vibration is felt to separate brake torque variation from wheel, hub, tire, steering, and suspension causes.
intermediateBrake squeal can come from friction-surface behavior, hardware contact, contamination, temperature, or a dragging component. Separate an intermittent noise from signs of unsafe braking before choosing a repair.
intermediateA wheel that locks, a brake that stays applied, or a vehicle that pulls with heat or odor can become a control and fire hazard. Stop driving and separate friction, hydraulic, parking-brake, mechanical, and control evidence with the exact vehicle procedure.
professional recommendedGrinding or scraping during braking can indicate friction-material, hardware, rotor/drum, shield, bearing, or debris concerns. Braking performance and heat determine whether the vehicle should be driven at all.
professional recommendedThe generic EVAP monitor reported a system-level malfunction. The code identifies the monitored emissions system, not a failed cap, valve, hose, canister, sensor, or other specific part.
Generic codeThe control system reached a lean-condition diagnostic threshold for Bank 1. The data does not by itself prove a vacuum leak, MAF sensor, or fuel pump.
Generic codeThe control system reached a lean-condition diagnostic threshold for Bank 2. The data does not by itself prove a vacuum leak, MAF sensor, oxygen sensor, or fuel-delivery failure.
Generic codeThe control system reached a rich-condition diagnostic threshold for Bank 1. The data does not by itself prove an injector, fuel-pressure, MAF sensor, or oxygen-sensor failure.
Generic codeThe control system reached a rich-condition diagnostic threshold for Bank 2. The data does not by itself prove an injector, fuel-pressure, MAF sensor, or oxygen-sensor failure.
Generic codeThe control module detected cooling-system temperature behavior outside its expected performance range. The code does not by itself identify a thermostat, coolant-temperature sensor, fan, coolant level, radiator, water pump, or other failed part.
Generic codeThe generic EVAP monitor detected purge-flow behavior outside its expected strategy. The code does not prove the purge valve itself is failed; the flow path, sealing, sensing, electrical control, and vehicle-specific monitor conditions still have to be tested.
Generic codeThe catalyst monitor determined that Bank 1 oxygen-storage performance was below its calibrated threshold. The code alone does not prove the converter is the original cause.
Generic codeThe catalyst monitor determined that Bank 2 oxygen-storage performance was below its calibrated threshold. The code alone does not prove the converter is the original cause.
Generic codeThe generic DTC identifies a purge-control valve circuit condition. It does not prove the purge valve itself is mechanically or electrically failed; wiring, connectors, power/ground, driver control, and exact circuit design must be tested.
Generic codeThe generic DTC identifies an open-circuit condition in the purge-control valve circuit. It narrows the electrical fault type, but it still does not prove the purge valve itself is the failed part.
Generic codeThe generic DTC identifies a short-circuit condition in the purge-control valve circuit. It does not establish whether the short is in the device, harness, connector, supply/control path, or module driver.
Generic codeThe generic DTC identifies a vent-control circuit malfunction. It does not identify whether the fault is the vent device, wiring, connector, power/ground, control driver, or another exact-vehicle circuit condition.
Generic codeThe generic DTC identifies an open-circuit condition in the EVAP vent-control circuit. It does not prove the vent valve or solenoid itself is failed.
Generic codeThe generic DTC identifies a short-circuit condition in the EVAP vent-control circuit. It does not identify the exact location of the short or prove the vent device itself is the cause.
Generic codeThe generic DTC identifies a malfunction in the EVAP vent valve or solenoid control circuit. It is a circuit-level finding, not proof that the vent valve or solenoid should be replaced.
Generic codeThe EVAP monitor detected a small-leak or sealing condition. The code does not identify the physical leak location or prove which component failed.
Generic codeThe EVAP monitor detected a very small leak or inability to maintain the expected seal. The code does not identify the leak location or prove a specific valve, cap, hose, or canister failed.
Generic codeThe EVAP monitor detected a large-leak or inability-to-seal condition. It does not identify where the leak or control fault is located.
Generic codeThe engine did not reach the expected temperature behavior under the monitor’s conditions. The thermostat is one possibility, not the only one.
Generic codeThe control module detected coolant-temperature sensor behavior outside the expected range or performance relationship. The code does not by itself prove the sensor, wiring, connector, actual engine temperature, or control strategy as the cause.
Generic codeThe control module detected a coolant-temperature sensor circuit signal in a low range for the vehicle’s monitoring strategy. The code does not by itself prove the sensor, wiring, connector, or engine temperature is the cause.
Generic codeThe control module detected a coolant-temperature sensor circuit signal in a high range for the vehicle’s monitoring strategy. The code does not by itself prove the sensor, wiring, connector, or engine temperature is the cause.
Generic codeThe control module reported a vehicle-speed-signal condition. The standardized code identifies the monitored speed-signal category; it does not prove which sensor, wheel-speed source, wiring path, module, or communication path is responsible.
Generic codeThe control module reported vehicle-speed-signal behavior outside its expected relationship. The standardized code identifies the monitored speed-signal category; it does not prove which sensor, wheel-speed source, wiring path, module, or communication path is responsible.
Generic codeThe control module detected a vehicle-speed-signal input below the range expected by its monitoring strategy. The generic code does not prove which sensor, wheel-speed source, wiring path, module, or communication path is responsible.
Generic codeThe control module detected intermittent, implausible, or high vehicle-speed-signal behavior. The generic code does not prove which sensor, wheel-speed source, wiring path, module, or communication path is responsible.
Generic codeApplies controlled pressure to a cool system for leak inspection. Never exceed the specified test pressure.
