C1A14 ECM

C1A14 ECM

Description

INFOID:0000000000965425

• ECM transmits the accelerator pedal position signal, ICC brake switch signal, stop lamp switch signal and

ICC steering switch signal, etc. to the ICC sensor integrated unit with CAN communication. 

• ECM controls the electronic control throttle based on the engine torque demand received from the ICC sen-

sor integrated unit with CAN communication. 

NOTE:
If DTC C1A14 is detected along with DTC U1000, first diagnose the DTC U1000. Refer to 

CCS-78,

"Diagnosis Procedure"

.

C1A15 GEAR POSITION

C1A15 GEAR POSITION

Description

INFOID:0000000000965428

ICC sensor integrated unit judges gear positions according to the following signals.
• A/T turbine revolution signal transmitted from TCM with CAN communication. 
• Gear ratio calculated from current gear position signal transmitted from TCM with CAN communication.
• Gear ratio calculated from vehicle speed signal transmitted from ABS actuator and electronic unit (control

unit) with CAN communication

NOTE:
If DTC C1A15 is detected along with DTC U1000, C1A03 or C1A04, first diagnose the DTC U1000, C1A03 or
