B2102
B2102 - Ignition Run/Start Input High
For a complete wiring diagram, refer to.
• When Monitored: With the ignition switch on.
• Set Condition: The wireless ignition node has detected the ignition switch input voltage more than a calibrated value.
Test Step 1 - Check for Active DTC
• Check to make sure the battery and charging system are operating properly. Battery and/or charging system problems may cause these DTCs to set.
• Diagnose any related powertrain DTCs before continuing.
• Turn the ignition ON.
• With a scan tool, read, record and erase WIN DTC.
• Perform 5 ignition cycles, leaving the ignition switch ON for a minimum of 30 seconds per cycle.
• Using the scan tool, read WIN DTC.
Does the scan tool display B2102 - Ignition Run/Start Input High?
Yes
• Go to Test Step 2
No
• The condition that caused this code to set is not present at this time. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
Test Step 2 - Check the WIN for an Internal Short to Voltage
• Turn the ignition OFF.
• Disconnect the WIN harness connector.
• With the scan tool, read DTCs.
Is the DTC active?
Yes
• Go to Test Step 3
No
• Replace the wireless ignition node.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
Test Step 3 - Ignition Switch Output Shorted to Battery Voltage
• Turn the ignition OFF.
• Disconnect the totally integrated power module C7 harness connector.
• Using a 12 volt test lamp connected to ground, probe the ignition switch output circuit in the WIN harness connector.
Does the test lamp illuminate brightly?
Yes
• Repair the circuit for a short to battery voltage.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
No
• Replace the ignition switch.
• Perform the Body Verification Test. Refer to => Non-DTC Based Diagnostics. Body Interior
