Check the relay for short-circuiting between #30(1) and #86(2).

HINT: When the relay is not drawn, there shall be open circuit between the system relay's #30(1) and #86(2). If not open circuit, the relay is damaged.

Check the signal cable between the system relay's socket #85(4) and Engine Control Module (ECM) #B16 (#C16) for short-circuiting to ground.

HINT: The system relay winding #86(2) is connected to kl:30 and #85(4) is connected to Engine Control Module (ECM) #B16 (#C6) and actively low.

Remedy as necessary.
