Inspection In Auto Active Test Mode
When auto active test mode is actuated, the following six steps are repeated three times.
(A): Oil pressure warning lamp is blinking when the auto active test is operating.
| Item Number | Test Item | Operation Time/Frequency |
|---|---|---|
| 1 | Rear window defogger | 10 seconds |
| 2 | Front wipers | LOW 5 seconds then HIGH 5 seconds |
| 3 | Daytime light system (Canada only) | 10 seconds |
| 3 | Tail, license, and parking lamps | 10 seconds |

| 4 | Headlamps (low) | 10 seconds |
| 4 | Headlamps (high) | ON-OFF 5 times |
| 5 | A/C compressor (magnet clutch) | ON-OFF 5 times |
| 6 | Cooling fan | LOW 2 seconds, MID 2 seconds, HIGH 2 seconds, MID 2 seconds, LOW 2 seconds |
Concept of Auto Active Test
- IPDM E/R actuates auto active test mode when it receives door switch signal from BCM via CAN communication line. Therefore, when auto active test mode is activated successfully, CAN communication between IPDM E/R and BCM is normal.
- If any of the systems controlled by IPDM E/R cannot be operated, possible cause can be easily diagnosed using auto active test.
