- Input the SC code to the diagnostic tester;
- Perform erase all key procedure.

 Erase key X

- Input the SC code to the diagnostic tester;
- Perform erase key X (X = 1, 2, 3, 4, 5) procedure.

Diagnostic Help

1. Connect X-431 3G diagnostic tester (the latest version) to the Data Link Connector (DLC), and make it

communicate with the vehicle electronic module by the data network.

2. Confirm that malfunction is current, and carry out the diagnostic test and repair procedures.
3. If DTC cannot be deleted, the malfunction is current.
4. Only use a digital multimeter to measure the voltage of the electrical system.
5. Refer to any Technical Bulletin that may apply to the malfunction.
6. Visually check related wire harness.
7. Check and clean all the immobilizer control module ground related to the current DTC.
8. If multiple trouble codes were set, use the circuit diagrams and look for any common ground circuit or

power supply circuit applied to the DTC.

CAUTION

 Add the old key (

See page 37-9

) after programming immobilizer control module.

 If both ECM and immobilizer control module are replaced at the same time, there are two cases, one, if

the immobilizer control module has no communication problem, replace the ECM first, and then perform
the ECM programming and match with immobilizer control module that need to be replaced, after that,
replace the immobilizer control module and programming the IMMO, and finally, immobilizer control
module matches the old key, there is no need to replace a new key. Two, if the immobilizer control
module has communication problem, replace the ECM, immobilizer control module and key with now
one and perform match all the systems.

Intermittent DTC Troubleshooting

If the malfunction is intermittent, perform the following:
 Check if connectors are loose.
 Check if wire harnesses are worn, pierced, pinched or partially broken.
 Monitor the X-431 3G diagnostic tester (the latest version) data that is related to this circuit.
 Wiggle related wire harness and connector and observe if the signal is interrupt in the related circuit.
 If possible, try to duplicate the conditions under which the DTC was set.
 Look for data that has changed or the DTC to reset during the wiggle test.
 Look for broken, bent, protruded or corroded terminals.
 Inspect sensor and mounting areas for damage, foreign matter, etc. that will cause incorrect signals.
 A data recorder and/or oscilloscope can be helpful in diagnosing the intermittent malfunction.

Ground Inspection

Groundings are very important to the proper operation of the electrical equipment and circuits. Groundings are
often exposed to moisture, dirt and corrosive elements. Corrosion (rust) may form additional resistance. This
additional resistance will change the way in which a circuit works.
Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can affect
the electronically controlled circuit. Perform the following operations when checking the groundings:
1. Remove the ground bolt or nut.
2. Check all the contact surfaces for tarnish, dirt, rust, etc.
3. Clean as necessary to ensure that the contacting is in a good condition.
4. Reinstall the bolt or nut securely.
5. Check for the accessories which may interfere with the ground circuit.
6. If several wires are crimped into one ground terminal, check for proper crimps. Make sure that all the wire

harnesses are clean, securely fastened and good contacted without crimping any excessive insulation
coat.
