• Make sure the following fusible links or IPDM E/R fuses are not blown.
  FUSIBLE LINK IDENTIFICATION
  
  

  Terminal No.	Signal Name	Fuse, Fusible Link No.
  1,2	Battery Power	F/L-C, F/L-E, Fuse No. 71, 78

OK or NG 

1. OK: GO TO 2.
2. NG: Replace fuse or fusible link.

1. Turn ignition switch OFF.
2. Disconnect IPDM E/R harness connector E3.
3. Check voltage between IPDM E/R harness connector E3 terminals 1 (W/R), 2 (W/L) and ground.
   1. 1 (W/R), 2 (W/L) - Ground: Battery voltage should exist 

OK or NG 

1. OK: GO TO 3.
2. NG: Replace IPDM E/R power supply circuit harness.
