18 C1304 -
01
Steering Torque
Sensor -
General
Electrical Failure
1) Internal electrical failure
in torque sensor
1) Do an ignition Off-On. If the error
still persists replace the steering
column.
19 C1305 -
01
Steering Rotor
Position Sensor
- General
Electrical Failure
1) Internal electrical
(internally senor damaged)
failure in rotor position
sensor.
1) Do an ignition Off-On. If the error
still persists replace the steering
column.
20 C1305 -
02
Steering Rotor
Position Sensor
- General signal
failure
1) Internal signal (signal out
of range) failure in rotor
position sensor.
1) Do an ignition Off-On. If the error
still persists replace the steering
column.
21 C1312 -
62
Rotor Position
Sensor Signal
"A" to "B" -
signal compare
failure
1) Values from both signals
output from sensor are not
coherent to each other
(Faulty sensor)
1) Reset the ECU. Remove the power
plug from ECU and reconnect after
about 5 minutes, If error still persists
replace the steering column.
22 C1314 -
19
Drive Motor “A”
Phase Current -
circuit current
above threshold
1) Motor current
consumption above the max
limit for a time interval.
1) Check wiring Connections &
connectors of power supply if
damaged than Replace the vehicle
wiring harness or connector.
2) Remove the power supply
connector and check the voltage (+12
V at connector which is directly from
the battery). If connector Voltage <
9V, check the battery.
If error still persists replace the ECU
23 C1314 -
01
Drive Motor “A”
Phase Current -
General
Electrical Failure
1) Internal ECU motor driver
circuit failure
1) Check wiring Connections &
connectors of power supply if
damaged than Replace the vehicle
wiring harness or connector.
2) Remove the power supply
connector and check the voltage (+12
V at connector which is directly from
the battery). If connector Voltage <
9V, check the battery.
If error still persists replace the ECU
24 C1314 -
13
Drive Motor “A”
Phase Current -
circuit open
1) Any motor supply cable
(U phase, V phase, W
phase) is open circuit
1) Check wiring Connections &
connectors of power supply if
damaged than Replace the vehicle
wiring harness or connector.
2) Remove the power supply
connector and check the voltage (+12
V at connector which is directly from
the battery). If connector Voltage <
9V, check the battery.
If error still persists replace the ECU /
Steering Column
