RKE FOB 3 Performance - RKE Transmitter

B210D - Battery Voltage Low

For a complete wiring diagram, refer to.

• When Monitored: With the ignition switch ON.

• Set Condition: The wireless ignition node has detected the fused B+ input voltage less than a calibrated value.






Test Step 1 - Determining if DTC is Current

• Diagnose any related powertrain DTCs before continuing.

• With a scan tool, read and record DTCs.

• With the scan tool, clear DTCs.

• Perform 5 ignition cycles, leaving the ignition switch ON for a minimum of 90 seconds per cycle.

• Using the scan tool, read DTCs.

Does the DTC reset?

Yes

• Go to Test Step 3

No

• Go to Test Step 2

Test Step 2 - Intermittent Condition

• 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.

• Partial module ground.

• With the ignition ON, wiggle the related wires.

• Using a scan tool, read DTCs.

Does the DTC reset?

Yes

• Repair the wiring as necessary.

• Perform the WIN Verification Test. Refer to => Non-DTC Based Diagnostics. Wireless Ignition Node Verification Test

No

• DTC is not active at this time. Test complete.

Test Step 3 - Fused B+ Circuit Open

• Check the related fuses to the fused B+ circuit. If the fuse is found to be open repair the circuit for a shorted condition.

• Turn the ignition OFF.

• Disconnect the WIN harness connector.

• Turn the ignition ON.

• Using a 12 volt test lamp connected to ground, probe the fused B+ circuit in the WIN harness connector.

Does the test lamp illuminate brightly?

Yes

• Go to Test Step 4

No

• Repair the fused B+ circuit for an open.

• Perform the WIN Verification Test. Refer to => Non-DTC Based Diagnostics. Wireless Ignition Node Verification Test

Test Step 4 - WIN

• A dirty (partial) ground can cause abnormal conditions within a system. Ensure the module has a good ground before continuing.

• Turn the ignition OFF.

• Connect the WIN connector.

• Back probe the fused B+ circuit.

• Start the engine.

• Using the scan tool, view battery voltage under Data Display in the Engine category.

• 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 +/- 0.5 volt?

Yes

• Replace and program the wireless ignition node.

• Perform the WIN Verification Test. Refer to => Non-DTC Based Diagnostics. Wireless Ignition Node Verification Test

No

• Repair the fused B+ circuit for high resistances.

• Perform the WIN Verification Test. Refer to => Non-DTC Based Diagnostics. Wireless Ignition Node Verification Test
