Hazard
In the electronic control unit for the transfer case of four-wheel-drive vehicles, the power supply circuit of the signal converter is inadequate when a speed limiter is retrofitted. As a result, momentary overcurrent flows through the transfer case electronic control unit during key switch operation, and repetition of this can damage internal circuits, potentially causing the transfer case, speed limiter, and speedometer to become inoperative.

４輪駆動車の副変速機用電子制御装置において、速度抑制装置（スピードリミッター）を後付けした際の信号変換器の電源供給回路が不適切なものがある。 そのため、キースイッチ操作時に副変速機用電子制御装置に瞬間的な過電流が流れ、その繰返しによって内部回路が損傷し、副変速機、速度抑制装置及び速度計が不作動となるおそれがある。
Remedy
All vehicles: Replace the signal converter power supply circuit and transfer case electronic control unit with corrective parts.
