Note
When replacing the combination meter assembly, make sure to replace it with a new one.
When replacing the pre-crash safety city sensor, replace it with a new one. If an ECU which was installed to another vehicle is used, the information stored in the pre-crash safety city sensor will not match the information from the vehicle and, as a result, a DTC may be output.
Tech Tips
Use the table below to help determine the cause of problem symptoms. If multiple suspected areas are listed, the potential causes of the symptoms are listed in order of probability in the "Suspected Area" column of the table.
Check each symptom by checking the suspected areas in the order they are listed. Replace parts as necessary.
| Symptom | Suspected Area | See page |
|---|---|---|
| "CHECK PRE-CRASH SAFETY." is displayed and PCS warning light is blinking. (for Multi-information Display [Monochrome Type]) | Pre-crash safety city sensor | |
| Combination meter assembly | ||
| "Check Pre-Crash Safety." is displayed and PCS warning light is blinking. (for Multi-information Display [Color Type]) | Pre-crash safety city sensor | |
| Combination meter assembly | ||
| "FRONT SENSOR SYSTEMS ARE TEMP. UNAVAILABLE DUE TO INAPPROPRIATE TEMPERATURE. WAIT A MOMENT." is displayed and PCS warning light is illuminating. (for Multi-information Display [Monochrome Type]) | The pre-crash safety city sensor temperature is extremely high or low and the system does not operate. When the temperature returns to normal, normal control returns (high or low temperature history can be checked using the Data List). | - |

| "FRONT SENSOR SYSTEMS ARE TEMP. UNAVAILABLE DUE TO BLOCKED VISION. CLEAN WINDSHIELD." is displayed and PCS warning light is illuminating. (for Multi-information Display [Monochrome Type]) | The pre-crash safety city sensor is determined to be unable to detect obstacles due to dirt. When dirt is removed, normal control returns (radar dirt history can be checked using the Data List). | - |
