Pinpoint Test S: THE PARKING AID MODULE DOES NOT RESPOND TO THE DIAGNOSTIC TOOL

S1 CHECK THE PARKING AID MODULE C4014B FOR DAMAGE
- Key in OFF position.
- Disconnect: Parking Aid Module C4014b.
- Inspect the parking aid module C4014b for damage.
- Is the parking aid module C4014b OK?
- Yes : GO to S2.
- No : REPAIR the parking aid module C4014b. CARRY OUT the diagnostic tool data link test.
S2 CHECK CIRCUIT 4-GN10 (GY) BETWEEN THE DATA LINK CONNECTOR (DLC) C251 AND THE PARKING AID MODULE C4014B FOR AN OPEN
- Measure the resistance between the parking aid module C4014b-1, circuit 4-GN10 (GY), harness side and the DLC C251-3, circuit 4-ED6 (GY), harness side.

- Is the resistance less than 5 ohms?
- Yes : REPAIR the circuit between joint connector No. 1 C261 and the DLC C251. CARRY OUT the diagnostic tool data link test.
- No : REPAIR joint connector No. 1 C261 as necessary. CARRY OUT the diagnostic tool data link test.
S7 CHECK FOR CORRECT PARKING AID MODULE OPERATION
- Disconnect all the parking aid module connectors.
- Check for:
- corrosion
- push-out pins
- Connect all the parking aid module connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
- Yes : INSTALL a new parking aid module. REFER to PARKING AID . TEST the system for normal operation.
  CARRY OUT the diagnostic tool data link test.
- No : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.
