B1303

Active Park Assist

Pinpoint Test E: DTC B1303:11

Refer to Wiring Diagram Set 131, Parking Aid for schematic and connector information Electrical Diagrams.

Normal Operation

The Parking Aid Module (PAM) receives a ground signal from the active park assist switch, enabling the system. A fault condition occurs when the PAM (Parking Aid Module) detects a short to ground on the active park assist switch signal circuit. The active park assist system does not activate and the message "ACTIVE PARK FAULT" in the Instrument Cluster (IC) message center is displayed followed by an audible chime.

- DTC B1303:11 (Park Assist Switch: Circuit Short To Ground)- sets when the active park assist switch signal circuit is shorted to ground, the normally open switch is stuck closed or the switch is pressed and held for more than 10 seconds.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors

- Active park assist switch

- PAM (Parking Aid Module)

PINPOINT TEST E : DTC B1303:11

NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

E1 CHECK FOR RECORDED DTCs FROM BOTH THE CONTINUOUS AND ON-DEMAND PAM (Parking Aid Module) SELF-TESTS

- Check for recorded PAM (Parking Aid Module) DTCs from the continuous and on-demand self-tests.

Is DTC B1303:11 recorded?

Yes
GO to E2.

No
REFER to DTC Charts Active Park Assist.

E2 CHECK THE ACTIVE PARK SWITCH FOR AN INTERNAL SHORT

- Disconnect: Active Park Assist Switch C2035.

- Clear the DTC and repeat the PAM (Parking Aid Module) self-test.

Is DTC B1303:11 recorded?

Yes
GO to E3.

No
INSTALL a new active park assist switch. REFER to Active Park Assist Switch . CLEAR the DTCs. TEST the system for normal operation.

E3 CHECK THE ACTIVE PARK SWITCH SIGNAL CIRCUIT FOR A SHORT TO GROUND

- Disconnect: PAM (Parking Aid Module) C4014.

- Measure the resistance between the active park assist switch C2035-6, circuit CMP18 (GN/BN), harness side and ground.





Is the resistance greater than 10,000 ohms?

Yes
GO to E4.

No
REPAIR circuit CMP18 (GN/BN). CLEAR the DTCs. TEST the system for normal operation.

E4 CHECK FOR CORRECT PAM (Parking Aid Module) OPERATION

- Connect: Active Park Assist Switch C2035.

- Disconnect the PAM (Parking Aid Module) connector.

- Check for:
- corrosion

- damaged pins

- pushed-out pins


- Connect the PAM (Parking Aid Module) connector and make sure it seats correctly.

- Operate the system and verify the concern is still present.

Is the concern still present?

Yes
INSTALL a new PAM (Parking Aid Module). CLEAR the DTCs. TEST the system for normal operation.

No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
