P
DTC C1280, C1730, C1951, C1952, C1959 Combine sensor
DETECTION
CONDITION
• C1280:
— Yaw rate sensor part 0-point correction value is 3 or more, or 2 or less.
— Output voltage value from yaw rate sensor part remains absolutely unchanged.
— Difference between estimated yaw rate value, calculated from wheel speed-sensor, lateral-G
sensor, steering angle sensor, and the value output from yaw rate sensor exceeds specification.
• C1730
— Voltage to combine sensor is detected out of range.
• C1952:
— Voltage of yaw rate sensor monitor is detected at 3.5 V or less.
• C1951:
— Monitor voltage of lateral-G sensor is detected at 4.5 V or more, or 0.5 V or less.
— Monitor voltage difference of 1.25 V or more, within 1 cycle is detected 8 times in 1 second.
• C1959:
— Lateral-G sensor part 0-point correction value is 3 or more, or 2 or less.
— Output voltage value from lateral-G sensor part remains absolutely unchanged.
— Difference between estimated lateral-G force calculated from steering angle sensor, and the value
output from lateral-G sensor exceeds specification.
POSSIBLE
CAUSE
• Open circuit in harness between combine sensor terminal C and DSC HU/CM terminal P
• Open, short to power, or short to ground circuit in harness between DSC HU/CM terminal T and
Combine sensor terminal D
• Open circuit, short to power, or short to ground in harness between DSC HU/CM terminal O and
combine sensor terminal B
• Open circuit in harness between combine sensor terminal E and DSC HU/CM terminal Y
• Open circuit, short to power, or short to ground in harness between DSC HU/CM terminal S and
combine sensor terminal F
• Malfunction of combine sensor
