No.5 DETECTS VEHICLE SPEED OF 10 km/h {6.2 mph} OR MORE [PARKING SENSOR]

id0903z4886800

5 | Detects vehicle speed of 10 km/h {6.2 mph} or more
DESCRIPTION | • Parking sensor detects obstruction while in position other than R position and at a speed other than 10 km/h {6.2 mph} or more.
POSSIBLE CAUSES | • Vehicle speed signal malfunction ― Open circuit in wiring harness between instrument cluster terminal 1O and parking sensor control module terminal 1E. ― Short to power supply or ground in wiring harness between instrument cluster terminal 1O and parking sensor control module terminal 1E. ― Instrument cluster malfunction ― Vehicle speed signal output to instrument cluster malfunction • Parking sensor control module malfunction

Diagnostic Procedure

Step | Inspection | Action
--- | --- | ---
1 | DETERMINE IF MALFUNCTION CAUSE IS SPEEDOMETER VEHICLE SPEED SIGNAL INPUT RELATED • Verify the speedometer display. • Does the speedometer indicate the actual vehicle speed? | Yes | Go to the next step.
No | For instrument cluster malfunctions, perform the procedure in “NO. 7 SPEEDOMETER INDICATION IS DEFECTIVE [INSTRUMENT CLUSTER]”.
2 | PARKING SENSOR CONTROL MODULE TERMINAL INSPECTION • Verify the connection condition of parking sensor control module connector terminal 1E (bad contact, bad connection). • Is the connection normal? | Yes | Go to the next step.
No | Repair or replace the malfunction location.
3 | VERIFY IF MALFUNCTION CAUSE IS OPEN CIRCUIT IN WIRING HARNESS BETWEEN PARKING SENSOR CONTROL MODULE AND INSTRUMENT CLUSTER • Turn the ignition switch to the OFF position. • Disconnect the parking sensor control module and instrument cluster connectors. • Verify if there is continuity between parking sensor control module 1E terminal and instrument cluster terminal 1O. • Is there continuity? | Yes | Go to the next step.
No | Repair the open circuit in the wiring harness.
4 | VERIFY IF MALFUNCTION CAUSE IS SHORT TO GROUND IN WIRING HARNESS BETWEEN PARKING SENSOR CONTROL MODULE AND INSTRUMENT CLUSTER • Leave the parking sensor control module and instrument cluster connectors disconnected. • Verify if there is continuity between the parking sensor control module terminal 1E and body ground. • Is there continuity? | Yes | Repair for a short to the wiring harness ground.
No | Go to the next step.
5 | VERIFY IF MALFUNCTION CAUSE IS SHORT TO POWER SUPPLY IN WIRING HARNESS BETWEEN PARKING SENSOR CONTROL MODULE AND INSTRUMENT CLUSTER • Leave the parking sensor control module and instrument cluster connectors disconnected. • Turn the ignition switch to the ON position. • Measure the voltage between the parking sensor control module terminal 1E and body ground. • Is the voltage 5 V or more? | Yes | Repair for a short to the wiring harness power supply.
No | Replace the parking sensor control module. (See PARKING SENSOR CONTROL MODULE REMOVAL/INSTALLATION.)
