SYMPTOM/CONDITION:
The service flash corrects the following conditions:
^ Intermittent no start
^ Intermittent RKE function
The above conditions may be caused by a software lockup in the module. The lockup condition may be cleared by removing and reinserting fuse M27.
Flash reprogramming the WIN will correct these conditions.
DIAGNOSIS:
Verify that the Wireless Ignition Node is functioning as designed. If DTC's are present, record them on the repair order and repair as necessary before proceeding further.
If a customer's VIN is listed in VIP or your RRT VIN list, perform the repair. For all other customers that describe the symptom/condition, perform the Repair Procedure.
REPAIR PROCEDURE:
WARNING:**If this flash process is interrupted/aborted, Do NOT cycle the ignition. The diagnostic session requires the WIN to report the ignition position and with a failed/aborted flash the WIN can not report the ignition position. Cycling the key will result in a vehicle off road condition and Technical Advisor intervention and/or WIN replacement will be required.**
NOTE:
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.
NOTE:
If this flash process is interrupted/aborted, the flash should be restarted.
