2006 Chevrolet Suburban C1500, 5.3 ZSECTION Circuit/System Testing
WARNING: This page is about a different car, the 2007 GMC Sierra and 2007 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.

B1517 03, B1517 07

  1. If the DTC is history, refer to Charging System Test .
  2. Ignition On, record the voltage at the battery terminals. Observe the scan tool BCM battery positive voltage parameter. The battery terminal and BCM parameter should not differ by more than 2 volts.
    • If not within the specified range, test the B+ circuits of the BCM C3 terminal 3 and C4 terminal 10 to ground circuit C4 terminal 9.
    • If not within the specified range, test the B+ circuits for a short to ground or an open/high resistance and the ground circuit for an open/high resistance.
  3. If all the circuits test normal, test or replace the BCM.
IMPORTANT: Poor or intermittent connections at G108 and G102 may cause this DTC to set.

B1517 5A

  1. Verify ground connections at G108 and G102 are clean and tight. Refer to Power and Grounding Component Views .
  2. Ignition OFF, disconnect the harness connectors C3 and C4 from the BCM.
  3. Ignition OFF, test for less than 1.0 ohm of resistance between the ground circuit C4 terminal 9 and ground.
    • If not within the specified range, test the circuit for an open/high resistance.
  4. Ignition On, test the B+ circuits C3 terminal 3 and C4 terminal 10 to the ground circuit C4 terminal 9. The B+ circuits should not differ by more than 2 volts.
    • If not within the specified range, test the circuit for a short to ground or an open/high resistance.
  5. If all circuits test normal, replace the BCM.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
