Circuit/System Testing

WARNING: This page is about a different car, the 2012 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:

The vehicle may be equipped with sectioned coax. Test each section and replace only the faulty section, not the entire length of coax.

  1. Ignition OFF, disconnect the GPS and cellular coax cable connector at the VCIM.
  2. Using the EL-49903  kit (EL-49903-5  adapter and EL-49903-4  coax cable), connect the EL-49903  kit to the VCIM.
  3. Clear the DTCs and operate the vehicle within the conditions for running the DTC. Verify DTC B2470 does not set.
    • If the DTC sets, replace the VCIM.
  4. Ignition OFF, disconnect the EL-49903  kit from the VCIM and perform the coax cable test on the coax cable between the VCIM and the cellular phone antenna.
    • If the coax cable does not pass the test, replace the coax cable.
  5. If all circuits test normal, replace the cellular phone antenna.
