Problem Symptoms Table [09/2014 - 10/2015]
HINT:
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.
PRE-COLLISION SYSTEM
| Symptom | Suspected Area | Reference |
|---|---|---|
| "Check PCS system" is displayed | Seat belt control ECU | Refer to REMOVAL [09/2014 - 10/2015] |
| Combination meter assembly | Refer to REMOVAL [09/2014 - ] | |
| Driving support ECU | Refer to REMOVAL [09/2014 - 10/2015] | |
| "PCS temporarily not available" is displayed | System determines that obstacles cannot be detected due to front millimeter wave radar sensor or radiator grille being dirty. If dirt is removed, normal control returns (dirt history can be checked using Data List). | - |
| System determines that obstacles cannot be detected due to rear millimeter wave radar sensor or rear bumper cover being dirty. If dirt is removed, normal control returns (dirt history can be checked using Data List). | - | |
| System determines that millimeter wave radar sensor assembly cannot detect obstacles due to bad weather. If weather recovers, normal control returns (bad weather history can be checked using Data List). | - | |
| When seat belt is retracted a certain number of times, overheating prevention fail-safe function of seat belt control ECU operates. If ECU temperature drops, normal control returns. | - | |
| Millimeter wave radar sensor assembly | Refer to REMOVAL [09/2014 - 10/2015] | |
| Seat belt control ECU | Refer to REMOVAL [09/2014 - 10/2015] | |
| Driving support ECU | Refer to REMOVAL [09/2014 - 10/2015] | |
| Driver monitor camera | Refer to REMOVAL [09/2014 - 10/2015] | |
| Although there is possibility of collision, pre-collision control (all front collision controls) does not operate ("PCS temporarily not available" is not displayed) | Vehicle condition/environment does not match pre-collision control operation conditions (confirm control operation conditions) | - |
| Check installation condition of millimeter wave radar sensor assembly | Refer to INSTALLATION [09/2014 - 10/2015] | |
| Perform millimeter wave radar sensor assembly adjustment | Refer to ADJUSTMENT [09/2014 - 10/2015] | |
| Millimeter wave radar sensor assembly | Refer to REMOVAL [09/2014 - 10/2015] | |
| Driving support ECU | Refer to REMOVAL [09/2014 - 10/2015] | |
| Although there is no possibility of collision, pre-collision control (all front collision controls) operates | Check installation condition of millimeter wave radar sensor | Refer to INSTALLATION [09/2014 - 10/2015] |
| Perform millimeter wave radar sensor adjustment | Refer to ADJUSTMENT [09/2014 - 10/2015] | |
| Millimeter wave radar sensor assembly | Refer to REMOVAL [09/2014 - 10/2015] | |
| Driving support ECU | Refer to REMOVAL [09/2014 - 10/2015] | |
| Only pre-collision seat belt does not operate | Buckle switch error (malfunction in which DTC is not output, such as when buckle switch is stuck ON or OFF) | - |
| Seat belt control ECU | Refer to REMOVAL [09/2014 - 10/2015] | |
| Pre-collision system cannot be canceled (pre-collision warning indicator does not blink) | Combination meter assembly (check if indicator illuminates using Active Test) | Refer to DATA LIST / ACTIVE TEST [09/2014 - 10/2015] |
| Inspect pre-collision system cancel switch assembly | Refer to REMOVAL [09/2014 - 10/2015] | |
| Wire harness between pre-collision system cancel switch and driving support ECU | - | |
| Driving support ECU | Refer to REMOVAL [09/2014 - 10/2015] |
