Diagnostic Test

WARNING: This page is about a different car, the 2006 Dodge Magnum, 2006 Dodge Charger, and 2006 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

1) ACTIVE DTC
Ignition on, engine not running.

With a scan tool, read DTC.

Is the DTC active at this time?

Yes
1. Go To 2).
No
1. Refer to INTERMITTENT CONDITION .
2. Perform POWERTRAIN VERIFICATION TEST .
2) SHORT RUNNER VALVE SOLENOID OPERATION
Turn the ignition off.

Disconnect the SRV Solenoid harness connector.

Ignition on, engine not running.

Using a 12-volt test light, connect one end to the (K236) SRV Control circuit and the other end the (Z904) Ground circuit in the SRV Solenoid harness connector.

With the scan tool, actuate (Toggle) the SRV Solenoid.

Does the test light illuminate brightly and flash on and off?

Yes
1. Replace the Short Runner Valve Solenoid.
2. Perform POWERTRAIN VERIFICATION TEST .
No
1. Go To 3).
3) (K343) FUSED AUTO SHUT DOWN RELAY OUTPUT2 CIRCUIT OPEN

Turn the ignition off.

Disconnect the Short Runner Valve Solenoid harness connector.

Turn the ignition on.

Using the scan tool, actuate (Toggle) the ASD Relay.

Using a 12-volt test light connected ground, probe the Fused ASD Relay Output circuit in the SRV Solenoid harness connector.

Does the test light illuminate brightly and flash on and off?

Yes
1. Go To 4).
No
1. Repair the (K343) Fused ASD Relay Output circuit.
2. Perform POWERTRAIN VERIFICATION TEST .
4) (K236) SRV CONTROL CIRCUIT SHORT TO BATTERY VOLTAGE

Turn the ignition off

Disconnect the PCM harness connectors.

Turn the ignition on.

Measure the voltage of the (K236) SRV Control circuit in the SRV Solenoid harness connector.

Does the voltage indicate voltage present?

Yes
1. Repair the short to voltage in the SRV Control circuit.
2. Perform POWERTRAIN VERIFICATION TEST .
No
1. Go To 5).
5) (K236) SRV CONTROL CIRCUIT SHORT TO GROUND

Turn the ignition off.

Measure the resistance between the (K236) SRV Control circuit in the SRV Solenoid harness connector and ground.

Is the resistance below 100 ohms?

Yes
1. Repair the short to ground in the (K236) SRV Control circuit.
2. Perform POWERTRAIN VERIFICATION TEST .
No
1. Go To 6).
6) (K236) SRV CONTROL CIRCUIT OPEN

CAUTION: Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal to pin connection. Install Miller Special Tool #8815 to perform diagnosis.

Measure the resistance of the (K236) SRV Control circuit between from the SRV Solenoid harness connector to the appropriate terminal of the special tool.

Is the resistance below 5.0 ohms?

Yes
1. Go To 7).
No
1. Repair the open in the (K236) SRV Control circuit.
2. Perform POWERTRAIN VERIFICATION TEST .
7) PCM
NOTE: Before continuing, check the PCM harness connector terminals for corrosion, damage, or terminal push out. Repair as necessary.

Using the schematics as a guide, inspect the wire harness and connectors. Pay particular attention to all Power and Ground circuits.

Were there any problems found?

Yes
1. Repair as necessary.
2. Perform POWERTRAIN VERIFICATION TEST .
No
1. Replace and program the Powertrain Control Module per Service Information.
2. Perform POWERTRAIN VERIFICATION TEST .
