C2115 - Dynamics Sensor Supply Voltage HIGH






For a complete wiring diagram, refer to.

• When Monitored: Upon ignition ON, prior to switching the dynamics sensor supply circuit power ON.

• Set Condition: If the anti lock brake module detects voltage on the dynamics sensor supply circuit when the circuit's power is turned OFF.






Test Step 1 - Verify DTC Is Active

• Turn the ignition ON.

• With the scan tool, read and record the ABS DTCs.

• With the scan tool, read and record the Environmental Data to help identify the conditions in which the DTC was set.

• With the scan tool, erase the ABS DTCs.

• Cycle the ignition switch.

• With the scan tool, read the ABS DTCs.

Does this DTC reset?

Yes

• Go to Test Step 2 => [ Test Step 2 - Inspect Related Wiring Harness, Terminals, and Connectors ]

No

• Perform the ABS Intermittent Condition Test. Refer to => Non-DTC Based Diagnostics. ABS Intermittent Condition Test

Test Step 2 - Inspect Related Wiring Harness, Terminals, and Connectors

• Turn the ignition OFF.

• Test all related wiring for pinched, chafed, pierced and partially broken wires.

• Test all related connectors for broken, bent, pushed out and corroded terminals.

Were any problems found?

Yes

• Repair as necessary.

• Perform ABS Verification Test. Refer to => Non-DTC
Based Diagnostics. ABS Verification Test

No

• Go to Test Step 3 => [ Test Step 3 - Test Dynamics Sensor Supply Circuit Short for a Short
to Voltage ]

Test Step 3 - Test Dynamics Sensor Supply Circuit Short for a Short to Voltage






• Disconnect the anti lock brake module harness connector.

• Turn the ignition ON.

• Measure the voltage of the dynamics sensor supply Circuit.

Is the voltage more than 0.2 volts?

Yes

• Repair the dynamics sensor supply Circuit for a short to voltage.

• Perform ABS Verification Test. Refer to => Non-DTC
Based Diagnostics. ABS Verification Test

No

• Replace the anti lock brake module.

• Perform ABS Verification Test. Refer to => Non-DTC
Based Diagnostics. ABS Verification Test
