Test J
PINPOINT TEST J: THE POWER SUPPLY RELAY IS INOPERATIVE - SWITCHED SYSTEM POWER (SSP)4Test J1:
Test J2-J3:
Normal Operation
Battery voltage is supplied to the SSP4 relay through battery junction box (BJB) fuse 23 (30A). Ground for the relay coil is controlled by the front electronic module (FEM) and rear electronic module (REM) through circuit 31S-DG57 (BK/YE). When the SSP4 relay is energized, battery voltage is switched from the BJB to circuit 30S-DB16 (RD/GN).
Possible Causes
- circuit 31S-DG57 (BK/YE) open
- circuit 30S-DB16 (RD/GN) open
- BJB
- SSP4 relay
