B2206: Diagnosis and Testing

B2206 - Current VIN Missing/Mismatch

For a complete wiring diagram, refer to.

• When Monitored: With the ignition ON.

• Set Condition: The totally integrated power module will receive and monitor the VIN message from the PCM and record the VIN if different from the last VIN.






Test Step 1 - Test For Active DTCs

• With the scan tool, read the active DTCs.

• Cycle the ignition switch from OFF to ON at least 5 times, leaving the ignition ON for a minimum of 90 seconds per cycle.

• With the scan tool, read the active DTCs.

Does the scan tool display this DTC as active?

Yes

• Go to Test Step 2.

No

• If the DTC is stored, test for an intermittent condition. Visually inspect the related wiring harness connectors. Look for broken, bent, pushed out, or corroded terminals.

Test Step 2 - Test VIN in PCM

• With the scan tool compare the VIN that is programmed into the PCM to the VIN on the vehicle.

Does the VIN programmed into the PCM match the vehicles VIN?

Yes

• Inspect the wiring and connectors for damage or shorted circuits. If OK, replace and program the totally integrated power module.

• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior

No

• Program the correct VIN in the PCM and retest.
