| 4. | CHECK FOR DTCs* |
(a) Using the Techstream, Check for DTCs.
Chassis > Front Recognition Camera > Trouble Codes(b) Make a note of the output DTCs.
| Result | Proceed to |
|---|---|
| DTCs are not output | A |
| DTC C1AA800 is output | B |
| DTC other than C1AA800 is output | C |
| B | | GO TO DTC CHART (C1AA800) |
| C | | GO TO STEP 7 |
|
| 5. | CHECK VEHICLE CONTROL HISTORY* |
(a) Using the Techstream, check for vehicle control history (RoB).
Chassis > Front Recognition Camera > Utility| Tester Display |
|---|
| Vehicle Control History (RoB) |
(b) Make a note of the output vehicle control history (RoB).
| Result | Proceed to |
|---|---|
| Vehicle control history (RoB) is not output | A |
| Vehicle control history (RoB) other than X2015 and X201C is output | |
| Vehicle control history (RoB) X2015 or X201C is output | B |
| B | | GO TO VEHICLE CONTROL HISTORY (X2015 or X201C) |
|
| 6. | RECONFIRM VEHICLE CONTROL HISTORY* |
(a) Using the Techstream, clear the vehicle control history (RoB).
Chassis > Front Recognition Camera > Utility| Tester Display |
|---|
| Vehicle Control History (RoB) |
(b) Using the Techstream, check for vehicle control history (RoB).
Chassis > Front Recognition Camera > Utility| Tester Display |
|---|
| Vehicle Control History (RoB) |
| Result | Proceed to |
|---|---|
| Vehicle control history (RoB) is not output | A |
| Vehicle control history (RoB) is output | B |
| A | | GO TO SYMPTOM SIMULATION |
| B | | GO TO VEHICLE CONTROL HISTORY |
| 7. | RECONFIRM DTC OUTPUT* |
(a) Using the Techstream, Clear the DTCs.
Chassis > Front Recognition Camera > Clear DTCs(b) Reproduce the vehicle conditions that were present when the DTCs that were noted were stored.
HINT:
Refer to each corresponding DTC for details on the detection conditions.
