Pinpoint Test A: No Communication With The Parking Aid Module

WARNING: This page is about a different car, the 2006 Mercury Montego, 2006 Ford Freestyle, and 2006 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.

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

A1 CHECK CIRCUIT 972 (BK/WH) FOR VOLTAGE
- Key in OFF position.
- Disconnect: Parking Aid Module C3267.
- Key in ON position.
- Measure the voltage between the parking aid module C3267-1, circuit 972 (BK/WH), harness side and ground.

- Is the voltage greater than 10 volts?
Yes: GO to A2.

No: VERIFY the smart junction box (SJB) fuse 19 (10A) is OK. If OK, REPAIR the circuit. TEST the system for normal operation.
A2 CHECK CIRCUIT 1205 (BK) FOR AN OPEN
- Key in OFF position.
- Measure the resistance between the parking aid module C3267-4, circuit 1205 (BK), harness side and ground.
