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 and be sure to perform initialization. If a pre-crash safety city sensor 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 stored.
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 | Link |
|---|---|---|
| "Check Pre-Crash Safety." is displayed and PCS OFF warning light is blinking | Pre-crash safety city sensor | |
| Combination meter assembly | ||
| "Front sensor systems are temporarily unavailable due to inappropriate temp. Wait a moment." is displayed and PCS OFF warning light is blinking or illuminated | The pre-crash safety city sensor temperature is extremely high and the system will not operate. When the temperature returns to normal, normal control will return (Check History of High or Low Temperature). | |

| "Front sensor systems are temporarily unavailable due to blocked vision. Clean windshield." is displayed and PCS OFF warning light is blinking or illuminated | The pre-crash safety city sensor cannot detect obstacles due to dirt. When dirt is removed, normal control will return (Check History of Blockage). | |
