Automatic high beam switch off

10 kΩ or higher

Automatic high beam switch on

Below 1 Ω

If the result is not as specified, replace the turn signal switch.

HINT:

  • The left turn or right turn condition indicates a condition in which the turn signal switch will return to the neutral position after releasing your hand from the turn signal switch (turn signal switch is operated approximately 6.3°).
  • The full left turn or full right turn condition indicates a condition in which the turn signal switch will not return to the neutral position after releasing your hand from the turn signal switch (turn signal switch is operated 10.5°).

 Abnormal Zero Point of Steering Angle Sensor (C1290)

DESCRIPTION The skid control ECU (brake booster with master cylinder assembly) acquires the steering angle sensor zero point every time the power switch on (READY) and the vehicle is driven at 35 km/h (22 mph) or more for approximately 5 seconds. The skid control ECU (brake booster with master cylin

 ECM Power Source Circuit

DESCRIPTION When the engine switch is turned on (IG), the battery voltage is applied to the IGSW terminal of the ECM. The output signal from the MREL terminal of the ECM causes a current to flow to the coil of the EFI-MAIN NO. 1 relay, closing the contacts and supplying power to terminals +B and +B2
