Adaptive Cruise Control (ACC) Unit

DTC 83: Adaptive cruise control (ACC)/LKAS indicator does not come on

Performance of the millimeter wave radar unit is not stable (Driving behind a target vehicle that caused unstable reception).

DTC 84: Adaptive cruise control (ACC)/LKAS indicator does not come on

Target vehicle comes closer than the millimeter wave radar unit detecting limits (The target vehicle brakes suddenly, etc.).

DTC 85: Adaptive cruise control (ACC)/LKAS indicator does not come on

Extensive driving on a rough road or a winding road, or VSA system detects problem. Check the VSA system.

DTC 86: Adaptive cruise control (ACC)/LKAS indicator does not come on

Abnormal tyre pressure, flat tyre.
(The tyre into which air pressure fell memorizes DTC.)
Check the all tyres and blow out, then make sure that the same tyres are installed.

DTC 87: Adaptive cruise control (ACC)/LKAS indicator does not come on

Adaptive cruise control (ACC) brake works continuously, or adaptive cruise control (ACC) brake control is temporarily prohibited by a communication line error detected between the adaptive cruise control (ACC) unit and VSA modulator-control unit.

DTC 88: Adaptive cruise control (ACC)/LKAS indicator does not come on

Millimeter wave radar unit temperature is high, millimeter wave radar unit supply voltage is low, or out of detection area.

DTC 89: Adaptive cruise control (ACC)/LKAS indicator does not come on

Front wheel spin

DTC 91: Adaptive cruise control (ACC)/LKAS indicator does not come on

Vehicle skidded, spun out, or abrupt steering wheel movements.

DTC 93: Adaptive cruise control (ACC)/LKAS indicator does not come on

Front tyre problem (different diameter of tyres, flat tyre, or large air pressure differential).
Check the tyre pressure and fix the blow out.

DTC 94: Adaptive cruise control (ACC)/LKAS indicator does not come on

Rear tyre problem (different diameter of tyres, flat tyre, or large air pressure differential).
Check the tyre pressure and fix the blow out.

DTC 95: Adaptive cruise control (ACC)/LKAS indicator does not come on

Power supply voltage is too high. Check the charging system.

DTC 96: Adaptive cruise control (ACC)/LKAS indicator does not come on

Power supply voltage is too low. Check the battery and charging system.

DTC 99: Adaptive cruise control (ACC)/LKAS indicator does not come on

Detects acceleration or deceleration that is out of the normal system operating range.

DTC 101: Adaptive cruise control (ACC)/LKAS indicator does not come on

Rear wheel locked (driving with the parking brake applied, or the parking brake stuck).

DTC 107: Adaptive cruise control (ACC)/LKAS indicator comes on

Millimeter wave radar unit aiming is incomplete.
Perform the re-aiming.
