Perform «*BODY VERIFICATION TEST»(/chrysler/crossfire/i-final-2008-2008/remont/communication-devices/#electronic-control-modules-electrical-diagnostics__body-verification-test) . No Repair the SCI Transmit circuit for a short to ground. Perform «*BODY VERIFICATION TEST»(/chrysler/crossfire/i-final-2008-2008/remont/communication-devices/#electronic-control-modules-electrical-diagnostics__body-verification-test) .

1. 1) MEASURE THE VOLTAGE OF THE DLC POWER CIRCUIT NOTE: If the LEDs do not light or no sound is emitted at start up, check for loose cable connections or a bad cable. Check the vehicle battery voltage (data link 16-way connector cavity 16). A minimum of 11 volts is required to adequately power the scan tool. Check for a proper ground at DLC cavity 4. If all connections are proper between the scan tool and the vehicle or other devices and the vehicle battery is fully charged, an inoperative scan tool may be the result of a faulty cable. Turn the ignition off. Measure the voltage of the Fused B(+) circuit at cavity 16 of the Data Link Connector. Is the voltage above 11 volts? Yes Go to step 2) . No System voltage must be above 11 volts. Check Fuse 14 in the Underhood Accessory Fuse Block. Repair the voltage concern as necessary. Perform «*BODY VERIFICATION TEST»(/chrysler/crossfire/i-final-2008-2008/remont/communication-devices/#electronic-control-modules-electrical-diagnostics__body-verification-test) .
2. 2) MEASURE THE RESISTANCE OF THE DLC GROUND CIRCUIT Measure the resistance between ground the Ground circuit at cavity 4 of the Data Link Connector. Is the resistance below 5.0 ohms? Yes Inspect the scan tool for a possible malfunction. Perform «*BODY VERIFICATION TEST»(/chrysler/crossfire/i-final-2008-2008/remont/communication-devices/#electronic-control-modules-electrical-diagnostics__body-verification-test) . No Repair the DLC Ground circuit for an open. Perform «*BODY VERIFICATION TEST»(/chrysler/crossfire/i-final-2008-2008/remont/communication-devices/#electronic-control-modules-electrical-diagnostics__body-verification-test) .

*BODY VERIFICATION TEST

Turn the ignition off.

Disconnect all jumper wires and reconnect all previously disconnected components and connectors.

Note. If the SKREEM or the PCM was replaced, refer to the service information for proper programming procedures.

If the Body Control Module was replaced, turn the ignition on for 15 seconds (to allow the new BCM to learn VIN) or engine may not start.

Program all RKE transmitters and other options as necessary.

With the scan tool, erase all Diagnostic Trouble Codes (DTCs) from ALL modules. Start the engine and allow it to run for 2 minutes. Operate all functions of the system that caused the original complaint.

Ensure that all accessories are turned off and the battery is fully charged.

Turn the ignition off and wait 5 seconds. Turn the ignition on and using the scan tool, read DTCs from ALL modules.

Are any DTCs present or is the original complaint still present?

Are any DTCs present?

YES

1. Repair is not complete, refer to appropriate symptom.

NO

1. Repair is complete.
