3E Ignition Run 2 Short

3E-IGNITION RUN 2 SHORT







- When Monitored:
With the ignition on.

- Set Condition:
When the output is active and the BCM detects the Ignition 1 circuit is low for at least 10 seconds.





1. COMPONENT OR MODULE SHORT TO GROUND

NOTE: Repeat this test until either the DTC is no longer present or all of the components are disconnected from the Fused Ignition Switch Output (Run) circuit and the DTC is still present.

1. Turn the ignition off.
2. This DTC may set with the component or the Fused Ignition Switch Output (Run) circuit to any of the following:
- Blower Motor Relay (In PDC)
- Rear Window Defogger Relay (In PDC)
- Back- Up Lamp Switch
- Right and Left Back- Up Lamps (Back- Up Lamp Switch Output circuit)

NOTE: For the result of this test to be valid, disconnect only one component at time and then verify if the DTC is still present.

3. Using the wiring diagram/schematic as a guide, disconnect the harness connector with the Fused Ignition Switch Output (Run) circuit from one component identified above.
4. Turn the ignition on.
5. With the scan tool in Body Computer, erase BCM DTCs.
6. Cycle the ignition from On to Off.
7. Turn the ignition on.
8. With the scan tool, read DTCs.

Does the scan tool display IGNITION RUN 2 OUTPUT SHORT?

Yes

- Go To 2

No

- Replace the module or the component that when disconnected, allowed this DTC to clear.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. (F20) FUSED IGNITION SWITCH OUTPUT (RUN) CIRCUIT SHORT TO GROUND

NOTE: All components identified in Test Number 1 must be disconnected from the BCM's Fused Ignition Switch Output (Run) circuit and the DTC must still be present for the result of the test to be valid.

1. Turn the ignition off.
2. Disconnect the BCM C3 harness connector.
3. Measure the resistance between ground and the (F20) Fused Ignition Switch Output (Run) circuits in the BCM C3 harness connector.
4. Using the wiring diagram/schematic as a guide, disconnect the appropriate component harness connector.

Is the resistance below 10k Ohms on any of the circuits?

Yes

- Repair the Fused Ignition Switch Output (Run) circuit for a short to ground.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Replace and program the Body Control Module.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
