| 1 | Front wiper | LO for 5 seconds --> HI for 5 seconds |
| 2 | Parking lamp License plate lamp Tail lamp Front fog lamp | 10 seconds |
| 3 | Headlamp | LO for 10 seconds -->HI ON <==> OFF 5 times |

Scheme 80: Concept of Auto Active Test
- IPDM E/R starts the auto active test with the door switch signals transmitted by BCM via CAN communication. Therefore, the CAN communication line between IPDM E/R and BCM is considered normal if the auto active test starts successfully.
- The auto active test facilitates troubleshooting if any systems controlled by IPDM E/R cannot be operated.

Note. The details of time display are as follows. CRNT: A malfunction is detected now. PAST: A malfunction was detected in the past. IGN counter is displayed on FFD (Freeze Frame data). The number is 0 when is detected now. The number increases like 1 --> 2... 38 --> 39 after returning to the normal condition whenever IGN OFF --> ON. The number is fixed to 39 until the self-diagnosis results are erased if it is over 39.
