Inspection in Auto Active Test

When auto active test is actuated, the following operation sequence is repeated 3 times.

Operation sequenceInspection locationOperation
1Front wiperLO for 5 seconds --> HI for 5 seconds
2Parking lamp License plate lamp Tail lamp Front fog lamp10 seconds
3HeadlampLO for 10 seconds -->HI ON <==> OFF 5 times
4A/C compressor (magnet clutch)ON <==> OFF 5 times
5Cooling fanLO for 5 seconds --> MID for 3 seconds --> HI for 2 seconds

Scheme 186: Concept of Auto Active Test
Scheme 186: Concept of Auto Active Test
  1. 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.
  2. The auto active test facilitates troubleshooting if any systems controlled by IPDM E/R cannot be operated.
