C2206-VEHICLE CONFIGURATION MISMATCH





When Monitored:

With the ignition on

Set Condition:

When the Anti-Lock Brake Module detects the signal from the gateway module relevant for vehicle characteristic is missing for a period greater than the specified fault duration





Diagnostic Test

1. CHECK FOR A DTC C2206-VEHICLE CONFIGURATION MISMATCH





NOTE: This DTC must be active for the results of this test to be valid.

Turn the ignition on.
With the scan tool, read and record DTC's.
With the scan tool, read and record Freeze Fame information.
With the scan tool, erase DTC's.
Cycle the ignition switch from off to on.
With the scan tool, read and record DTC's

Does the scan tool display: C22O6-VEHICLE CONFIGURATION MISMATCH?

Yes

- Go To 2

No

- Refer to the INTERMITTENT CONDITION diagnostic procedure. Testing and Inspection
- Perform ABS VERIFICATION TEST - VER 1. ABS Verification Test

2. CHECK THE WIRING HARNESS, TERMINALS, AND CONNECTORS





Visually inspect the related wiring harness. Look for any bruised chafed pierced or partially broken wires.

Using a 12-volt test light connected to 12-volts check the (D65) CAN C (+) BUS circuit.

Does the test light illuminate brightly?

Yes

- Repair the (D65) CAN C (+) BUS circuit for a short to ground.
- Perform ABS VERIFICATION TEST VER 1. ABS Verification Test.

No

- Go To 5

5. CHECK THE (D65) CAN C (+) BUS CIRCUIT FOR A SHORT TO VOLTAGE





Turn the ignition off.
Disconnect the Anti-Lock Brake Module harness connector.
Disconnect the Powertrain Control Module harness connector.
Turn the ignition on.
Using a 12-volt test light connected to ground check the (D65) CAN C (+) BUS circuit.

Does the test light illuminate brightly?

Yes

- Repair the (D65) CAN C (+) BUS circuit for a short to voltage.
- Perform ABS VERIFICATION TEST - VER 1. ABS Verification Test.

No

- Go To 6

6. CHECK THE (D65) CAN C (+) BUS CIRCUIT FOR AN OPEN CIRCUIT





Turn the ignition off.
Disconnect the Anti-Lock Brake Module harness connector.
Disconnect the Powertrain Control Module harness connector.
Measure the resistance of the (D65) CAN C (+) Bus circuit between the Anti-lock Brake Module and the Powertrain Control Module.

Is the resistance below 5.O ohms?

Yes

- Go To 7

No

- Repair the (D65) CAN C (+) BUS circuit for an open circuit.
- Perform ABS VERIFICATION TEST - VER 1. ABS Verification Test.

7. CHECK THE (D64) CAN C (-) BUS CIRCUIT FOR A SHORT TO GROUND





Turn the ignition off.
Disconnect the Anti-Lock Brake Module harness connector.
Disconnect the Powertrain Control Module harness connector.
Turn the ignition on.
Using a 12-volt test light connected to 12-volts check the (D64) CAN C (-) BUS circuit.

Does the test light illuminate brightly?

Yes

- Repair the (D64) CAN C (-) BUS circuit for a short to ground.
- Perform ABS VERIFICATION TEST - VER 1. ABS Verification Test.

No

- Go To 8

8. CHECK THE (D64) CAN C (-) BUS CIRCUIT FOR A SHORT TO VOLTAGE





Turn the ignition off.
Disconnect the Anti-Lock Brake Module harness connector.
Disconnect the Powertrain Control Module harness connector.
Turn the ignition on.
Using a 12-volt test light connected to ground check the (D64) CAN C (-) BUS circuit.

Does the test light illuminate brightly?

Yes

- Repair the (D64) CAN C (-) BUS circuit for a short to voltage.
- Perform ABS VERIFICATION TEST VER 1. ABS Verification Test.

No

- Go To 9

9. CHECK THE (D64) CAN C (-) BUS CIRCUIT FOR AN OPEN CIRCUIT





Turn the ignition off.
Disconnect the Anti-Lock Brake Module harness connector.
Disconnect the Powertrain Control Module harness connector.
Measure the resistance of the (D64) CAN C (-) Bus circuit between the Anti-Lock Brake Module and the Powertrain Control Module.

Is the resistance below 5.O ohms?

Yes

- Replace the Anti-Lock Brake Module.
- Perform ABS VERIFICATION TEST - VER 1. ABS Verification Test.

No

- Repair the (D64) CAN C (-) BUS circuit for an open circuit.
