DIAGNOSIS SYSTEM (IPDM E/R)
Diagnosis DescriptionINFOID:0000000006368066
AUTO ACTIVE TEST
Description
In auto active test, the IPDM E/R sends a drive signal to the following systems to check their operation.
 Oil pressure warning lamp
 Rear window defogger
 Front wiper (LO, HI)
 Parking lamp
 License plate lamp
 Tail lamp
 Side marker lamp
 Front fog lamp
 Headlamp (LO, HI)
 A/C compressor (magnet clutch)
Operation Procedure
CAUTION:
Never perform auto active test in the following conditions.
 Engine is running.
 CONSULT-III is connected.
1. Close the hood and lift the wiper arms from the windshield. (Prevent windshield damage due to wiper
operation)
