Circuit/System Verification

NOTE: Because of normal system communications between the BCM and ECM, any immobilizer B-codes must be diagnosed prior to the diagnosis of P-codes. Refer to the appropriate DTC.

If the DTC is set, perform the Immobilizer Relearn procedure. Refer to Immobilizer System Component Programming . If the DTC resets, replace the K20 Engine Control Module (ECM).
