The distance sensing cruise control module (DSCC) communicates with the radar forward looking sensor (FLS) via controller area network (CAN) serial data. When there is an internal fault in the FLS, this DTC will set in the DSCC.
The DSCC runs the program to detect a fault when power up is commanded.
The module has detected a fault with the FLS while cruise is engaged or attempted to be engaged.
• | The malfunction indicator lamp (MIL) will not illuminate. |
• | The adaptive cruise control (ACC) is disabled. |
• | The cruise control system is disabled. |
• | Service Radar Cruise message is displayed in the driver information center (DIC). |
• | The condition responsible for setting the DTC no longer exists. |
• | A history DTC will clear after 40 malfunction-free ignition cycles have occurred. |
An FLS radar out of alignment condition may be as a result of tampering with the DSCC module mounting structures/brackets or the adjuster settings. An out of alignment condition may also be a result of damage to the front section of the ACC equipped vehicle or the DSCC module.
