• Result:

• Result	Proceed to
  DTC is not output	A
  DTC is output	B

Disconnect the A14 skid control ECU with actuator connector.

Disconnect the A28 AFS ECU connector.

Measure the resistance according to the value(s) in the table below.

• Standard resistance:

• Tester Connection	Condition	Specified Condition
  A14-37 (FRO) - A28-7 (SPDR)	Always	Below 1 Ω
  A14-38 (FLO) - A28-6 (SPDL)	Always	Below 1 Ω
  A28-7 (SPDR) - Body ground	Always	10 kΩ or higher
  A28-6 (SPDL) - Body ground	Always	10 kΩ or higher

Disconnect the A28 AFS ECU connector.

Measure the voltage according to the value(s) in the table below.

• Standard voltage:

• Tester Connection	Condition	Specified Voltage
  A28-6 (SPDL) - Body ground	Vehicle is driving at approx. 30 km/h (19 mph)	0 to 5 V Pulse generation (see waveform 1)
  A28-7 (SPDR) - Body ground	Vehicle is driving at approx. 30 km/h (19 mph)	0 to 5 V Pulse generation (see waveform 1)
