Test I

PINPOINT TEST I: THE POWER SUPPLY RELAY IS INOPERATIVE - SWITCHED SYSTEM POWER (SSP) 3

Test I1-I2:

Test I2-I3:

Normal Operation
Battery voltage is supplied to the SSP3 relay through battery junction box (BJB) fuse 24 (30A). Ground for the relay coil is controlled by the front electronic module (FEM) and rear electronic module (REM) through circuit 31S-DG55 (BK/RD). When the SSP3 relay is energized, battery voltage is switched form the BJB to circuit 30S-DB15 (RD/OG).

Possible Causes
- circuit 30S-DB15 (RD/OG) open
- circuit 30-DG55 (RD/BK) open
- circuit 30-DG56 (RD/WH) open
- circuit 31S-DG55 (BK/RD) open
- BJB
- SSP3 relay
