Fault Code Parking Aid Module (PAM) (Freelander 2)

Parking assistance control unit

NOTE: If a unit or component is likely to fail and the vehicle is still under manufacturer's warranty, refer to the warranty manual before replacing the component (section B1.2) or determine if there is any previously approved special program in operation.

NOTE: Universal Scan Tools may not read the listed codes or may only read 5-digit codes. Match the 5 digits from the scan tool with the first 5 digits of the 7-digit code listed to identify the problem (the last 2 digits give additional information read by the diagnostic system approved by the manufacturer).

NOTE: Always use a digital multimeter when performing voltage or resistance tests (DMM) accurate to three decimal places and with a valid calibration certificate. When testing resistance, be sure to consider the resistance of the DMM leads.

NOTE: Before starting diagnostic programs using troubleshooting tests, check and correct major problems.

NOTE: Inspect the connectors for signs of water intrusion and their pins for damage and (or) traces of corrosion.

NOTE: If DTCs are logged and there is no problem after performing troubleshooting tests, an intermittent problem may be the cause. Be sure to check for loose connections and corroded contacts.
