Wireless Ignition Node (WIN)
B210E-BATTERY VOLTAGE HIGH
For a complete wiring diagram, refer to the Wiring Information Electrical Diagrams.
- When Monitored:
With the ignition switch on.
- Set Condition:
The Wireless Ignition Node (WIN) has detected the Fused (B+) input voltage above a calibrated value.
1. DETERMINING IF DTC IS CURRENT
NOTE: Diagnose any related Powertrain DTCs before continuing.
1. With a scan tool, read and record DTCs.
2. With the scan tool, clear DTCs.
3. Perform 5 ignition cycles, leaving the ignition switch on for a minimum of 90 seconds per cycle.
4. Using the scan tool, read DTCs.
Does the DTC reset?
Yes
- Go To 3
No
- Go To 2
2. INTERMITTENT CONDITION
NOTE: Check for any of the follow conditions:
- Poor wire to terminal connection
- Corroded terminals
- Backed out or loose terminals
- Broken wire internal to the insulation
- Dirty (partial) module ground
1. With the ignition on, wiggle the related wires.
2. Using a scan tool, read DTCs.
Does the DTC reset?
Yes
- Repair the wiring as necessary.
- Perform the WIN VERIFICATION TEST. Vehicle Theft Security Verification Tests
No
- DTC is not active at this time. Test complete.
3. WIRELESS IGNITION NODE
NOTE: A dirty (partial) ground can cause abnormal conditions with a system. Make sure the module has a good ground before continuing.
1. Turn the ignition off.
2. Back probe the Fused (B+) circuit in the WIN harness connector.
3. Start the engine.
4. Using a scan tool, view the battery voltage under Data Display in the Engine category.
5. Compare the voltage on the scan tool to the voltage reading on the voltmeter.
Is the voltage on the scan tool equal to the voltmeter reading +/-.5 volt?
Yes
- Replace and program the Wireless Ignition Node. NOTE: If this vehicle is equipped with a Steering Column Lock Module, it must be replaced along with the WIN.
- Perform the WIN VERIFICATION TEST. Vehicle Theft Security Verification Tests
No
- Repair the Fused (B+) circuit. Perform the WIN VERIFICATION TEST. Vehicle Theft Security Verification Tests
