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 initialize the settings. 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 |
|---|---|---|
| PCS warning light (PCS OFF indicator) is blinking or illuminuting. | The pre-crash safety city sensor temperature is extremely high and the system will not operate. When the temperature return to normal, normal control will return (Check High or Low Temperature Status). | |
| The pre-crash safety city sensor cannot detect obstacles due to dirt. When dirt is removed, normal control will return (Check Lider Blockage Status). | ||
| The pre-crash safety system does not operate due to abnormal pre-crash safety city sensor voltage | ||

| Although there is possibility of collision, pre-crash control (all front collision controls) do not operate. (when PCS warning light [PCS OFF indicator] does not illuminate) | Vehicle condition/environment does not match pre-crash control operation conditions. (Confirm control operation conditions) | |
