Diagnostic Test

1. CHECK FOR DTC C1015–RIGHT FRONT WHEEL SPEED SENSOR CIRCUIT

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


Turn the ignition on.
With the scan tool, record and erase DTCs.
Cycle the ignition switch from off to on.
With the scan tool, read DTCs.

Does the scan tool display: C1015–RIGHT FRONT WHEEL SPEED SENSOR CIRCUIT?

Yes


No

2. CHECK CONNECTOR/TERMINAL FOR DAMAGE

NOTE: Check all terminals for broken, bent, pushed out, or corroded terminals.


Turn the ignition off.
Inspect the Anti-Lock Brake Module harness connector, Right Front WSS, and Right Front WSS harness connector.

Is the Right Front WSS or any of the connectors/terminals damaged?

Yes


No

3. CHECK (B7) RIGHT FRONT WSS 12 VOLT SUPPLY CIRCUIT VOLTAGE



Disconnect the Right Front WSS harness connector.
Turn the ignition on.
Measure the voltage of the (B7) Right Front WSS 12 Volt Supply circuit.

Is the voltage above 10.0 volts?

Yes


No

4. CHECK (B7) RIGHT FRONT WSS 12 VOLT SUPPLY CIRCUIT FOR A SHORT TO GROUND



Turn the ignition off.
Disconnect the Right Front WSS harness connector.
Disconnect the Anti-Lock Brake Module harness connector.
Using a 12-volt test light connected to 12-volts, probe the (B7) Right Front WSS Supply circuit.

Does the test light illuminate brightly?

Yes


No

5. CHECK (B7) RIGHT FRONT WSS 12 VOLT SUPPLY CIRCUIT FOR AN OPEN



Connect a jumper wire between ground and the (B7) Right Front WSS Supply circuit in the Anti-Lock Brakes Module harness connector.
Using a 12-volt test light connected to 12-volts, probe the (B7) Right Front WSS Supply circuit.

Does the test light illuminate brightly?

Yes


No

6. CHECK (B6) RIGHT FRONT WSS SIGNAL CIRCUIT SHORT TO GROUND



Using a 12-volt test light connected to 12-volts, probe the (B6) Right Front WSS Signal circuit.

Does the test light illuminate brightly?

Yes


No

7. CHECK (B6) RIGHT FRONT WSS SIGNAL CIRCUIT OPEN



Connect a jumper wire between ground and the (B6) Right Front WSS Signal circuit in the Anti-Lock Brakes Module harness connector.
Using a 12-volt test light connected to 12-volts, probe the (B6) Right Front WSS Signal circuit.

Does the test light illuminate brightly?

Yes


No

8. CHECK (B6) RIGHT FRONT WSS SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE



Turn the ignition on.
Remove all jumper wires.
Measure the voltage between the (B6) Right Front WSS Signal circuit and ground.

Is the voltage above one volt?

Yes


No

9. CHECK (B6) RIGHT FRONT WSS SIGNAL CIRCUIT AND (B7) RIGHT FRONT WSS 12 VOLT SUPPLY CIRCUIT SHORTED TOGETHER



Turn the ignition off.
Measure the resistance between the (B6) Right Front WSS Signal circuit and the (B7) Right Front WSS Supply circuit.

Is the resistance above 120 ohms?

Yes

10

No

10. RIGHT FRONT WHEEL SPEED SENSOR

Replace the Right Front Wheel Speed Sensor in accordance with the Service Information.
Perform ABS VERIFICATION TEST.
(Refer to 5 - BRAKES - STANDARD PROCEDURE).

CAUTION: Ensure brake capability is available before road testing.


Road test the vehicle over 40 km/h (25 mph).

NOTE: Vehicle must be driven above 40 km/h (25 mph) for set conditions to be met.


With the scan tool, read ABS DTCs.

Did DTC C1015–RIGHT FRONT WHEEL SPEED SENSOR CIRCUIT reset?

Yes


No
