3. FUSED IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT OPEN NOTE: Check the related fuses to the Fused Ignition Switch Output (Run-Start) circuit. If the fuse is found Disconnect the SKREEM harness connector. Turn the ignition on. Using a 12 volt test light connected to ground, probe the Fused Ignition Switch Output (Run-Start) circuit in the Does the test light illuminate brightly? Yes >> Go to 4 No >> Repair the Fused Ignition Switch Output (Run-Start) circuit for an open. Perform SKREEM VERIFICATION TEST. 4. FUSED (B+) CIRCUIT OPEN Turn the ignition off. Using a 12 volt test light connected to ground, probe the Fused (B+) circuit in the SKREEM harness connector. Does the test light illuminate brightly? Yes >> Go to 5 No >> Repair the Fused (B+) circuit for an open. Perform SKREEM VERIFICATION TEST. 5. SKREEM NOTE: Repeat the below procedure for both the Fused Ignition Switch Output (Run-Start) circuit and the NOTE: A dirty (partial) ground can cause abnormal conditions within a system. Ensure the module has a Reconnect the SKREEM connector. Back probe the Fused Ignition Switch Output (Run-Start) circuit and then the Fused (B+) circuit. Start the engine. Using the scan tool, view battery voltage under Data Display in the Engine category. Compare the voltage on the scan tool to the voltage reading on the voltmeter. Is the voltage on the scan tool equal to the voltmeter reading +/- .5 volt? Yes >> Replace and program the SKREEM in accordance with the Service Information. Perform SKREEM VERIFICATION TEST. No >> Repair the circuit(s) that indicated the incorrect voltage. Perform SKREEM VERIFICATION TEST. 8Q - 88 VEHICLE THEFT SECURITY - ELECTRICAL DIAGNOSTICS LX |
