The ECM continuously monitors its main and sub CPUs. This self-check ensures that the ECM is functioning properly. If outputs from the CPUs are different and deviate from the standard, the ECM will illuminate the MIL and store the DTC.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| P160700 | Cruise Control Input Processor | When prohibited by the sub-CPU, the cruise control system operates for 0.3 seconds or more. | ECM |
The ECM receives signals from each sensor to control all functions of the cruise control system. When a malfunction is detected, the fail-safe function operates until the ignition switch is turned off.
Clear the DTCs.
