Vehicle Theft Security System

B210E-BATTERY VOLTAGE HIGH

B210E - Battery Voltage High:

WHEN MONITORED
With the ignition switch on.

SET CONDITION
The SKREEM has detected the Fused (B+) input voltage above a calibrated value.

POSSIBLE CAUSES
- Fused (B+) circuit
- SKREEM

Diagnostic Test

1. DETERMINING IF DTC IS CURRENT

NOTE: Diagnose any related Powertrain DTC(s) before continuing.

With a scan tool, read and record DTC(s).
With the scan tool, clear DTC(s).
Perform 5 ignition cycles, leaving the ignition switch on for a minimum of 90 seconds per cycle.
Using the scan tool, read DTC(s).

Q: 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

With the ignition on, wiggle the related wires.
Using a scan tool, read DTC(s).

Q: Does the DTC reset?

YES: Repair the wiring as necessary. Perform SKREEM VERIFICATION TEST. Vehicle Theft Security Verification Tests
NO: DTC is not active at this time. Test complete.

3. SKREEM

NOTE: A dirty (partial) ground can cause abnormal conditions with a system. Make sure the module has a good ground before continuing.

Turn the ignition off.
Back probe the Fused (B+) circuit in the SKREEM harness connector.
Start the engine.
Using a scan tool, view the battery voltage under Data Display in the Engine category. Compare the voltage on the scan tool to the voltage reading on the voltmeter.

Q: Is the voltage on the scan tool equal to the voltmeter reading +/- 0.5 volt?

YES: Replace and program the SKREEM.

NOTE: If this vehicle is equipped with a Steering Column Lock Module, it must be replaced along with the SKREEM. Perform SKREEM VERIFICATION TEST. Vehicle Theft Security Verification Tests
NO: Repair the Fused (B+) circuit. Perform SKREEM VERIFICATION TEST. Vehicle Theft Security Verification Tests
