Vehicle Speed Sensor Circuit (C1AA3)
DESCRIPTION
The forward recognition camera receives vehicle speed signals from the skid control
ECU. If the skid control ECU receives a vehicle speed sensor malfunction signal,
it informs the forward recognition camera via CAN communication, and DTC C1AA3 is
stored.
DTC No.
