DTC P1616 Communication Error from ECM to Distance Control ECU
DTC U0100 Lost Communication with ECM/PCM "A"
DESCRIPTION
The ECM receives signals from each sensor and ECU, then sends signals such as A/T signals, cruise control operation signals, low speed operation signals, brake control operation signals, and laser light emission prohibiting signals, to the distance control ECU. The ECM is the only component that has a function to record and output the DTCs in the dynamic laser cruise control system. Therefore, if the distance control ECU detects a communication error from the ECM, it sends a malfunction signal back to the ECM.

U0100 |
While the dynamic laser cruise control is either preparing for operation or operating, if the ECM continuously receives a communication cut off signal from the distance control ECU for more than a specific amount of time, the ECM records this communication cut off code |

Idle Control System Malfunction
DESCRIPTION
The idling speed is controlled by the ETCS (Electronic Throttle Control
System). The ETCS is comprised
of: 1) the one valve type throttle body; 2) the throttle actuator, which
operates the throttle valve; 3) the
Throttle Position (TP) sensor, which detects the opening angle of ...
