Pinpoint Test H: The Power Supply Relay Is Inoperative - Switched System Power (SSP) 2

WARNING: This page is about a different car, the 2004 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: The ignition switch must be cycled from OFF to ON to enable the SSP feature.

NOTE: Refer to EXTERIOR LIGHTING and the SSP Relay Index for complete details of SSP 1 powered features.

H1 CHECK THE BATTERY JUNCTION BOX (BJB)
- Key of OFF position.
- Disconnect SSP2 Relay C442.
- Measure the voltage between the SSP2 relay C442-86, circuit 30-DG53 (RD/OG), harness side and ground; and between the SSP2 relay C442-30, circuit 30-DG54 (RD/GN), harness side and ground.

- Are the voltages greater than 10 volts?
1. Yes : GO to H2.
2. No : REPAIR or INSTALL a new BJB. TEST the system for normal operation.
H2 CHECK CIRCUIT 31S-DG53 (BK/OG) FOR AN OPEN
- Key in ON position.
- Measure the resistance between the SSP2 relay C442-85, circuit 31S -DG53 (BK/OG), harness side and ground.

- Is the resistance less than 5 ohms?
1. Yes : GO to H3.
2. No : REPAIR the circuit. TEST the system for normal operation.
H3 CHECK THE SSP2 RELAY
- Carry out the SSP2 relay component test.
  Refer to COMPONENT TESTING .
- Is the SSP2 relay OK?
1. Yes : REPAIR circuit 30-DD2 (RD/BU).
2. No : INSTALL a new SSP2 relay. TEST the system for normal operation.
