The service flash corrects the following conditions:
Fault Codes: B1606-95, B16AF-15, B16B3-15, B1632-15, and B1636-15
Trunk Lamps turn off after 30 seconds on the first time out delay after the ignition is cycled to OFF (A reduced time out delay after the first time out
is normal behavior. The ignition must be cycled before a full ten minute delay may be observed again).
Passive Entry response time seems slow. User will typically complain of having to pull the handle twice to get it to work.
If the vehicle operator describes any of the above Symptom/Condition, perform the Repair Procedure.
Install a battery charger to ensure battery voltage does not drop below 13.2 volts. Do not allow the charging voltage to climb above 13.5 volts during
the flash process.
If this flash process is interrupted/aborted, the flash should be restarted.
1. Verify that the Body Control Module is functioning as designed. If DTC's other then those listed are present, record them on the repair order and
repair as necessary before proceeding further.
The ignition must be in the OFF position in order to flash reprogram the BCM on Powernet vehicles.
2. Using the wiTECH Diagnostic Application for flashing Front Door Control Modules is made available through the wiTECH Diagnostic Application.
