Inflator unit Citroën C5 II 9660499380 5430F6

Description

Tire pressure control unit for Citroen C5 cars from 2005 to 2007

Part description

The underinflation unit (TPMS control unit) is used to evaluate the signals of the tire pressure control system and to transmit information to the vehicle. The offered part is intended for Citroën C5 cars and is particularly sought after by the original numbers 9660499380 and 5430F6.

A suitable solution in case of a malfunction of the pressure monitoring system, when it is necessary to replace the malfunctioning control unit with the correct type according to the marking.

Installation recommendations

Generally/typically for control units the exact procedure may vary depending on the specific car design and installation. Below is a practical procedure to approach the exchange safely and without unnecessary mistakes.

1) Before assembly

• Compare the markings on the part with the old unit: 9660499380 and/or 5430F6.
• Check the condition of the connectors (bent pins, corrosion, loose locking) and the integrity of the plastic body.
• If the fault was caused by water or oxidation, also check the wiring harness – replacing the unit alone may not solve the problem.

2) Necessary tools and materials (in general)

• Basic set of hand tools (screwdrivers/extensions according to design)
• Small flathead screwdriver or plastic pry bar to loosen connector fuses
• Electrical contact cleaner (as needed)
• Protective gloves

3) Step-by-step assembly procedure

1. Turn off the ignition and wait for the car’s electronics to go to sleep (typically a few minutes).
2. Disconnect the battery (minus pole) to reduce the risk of damaging the electronics.
3. Ensure access to the unit (removal of covers/panelling according to specific design).
4. Take a photo of the connection and wiring so that you can return everything to its original state.
5. Carefully unlock the connector(s) and disconnect them – do not pull on the cables, only the body of the connector.
6. Remove the original unit from the holder/mount.
7. Compare the old and new part (connectors, mounts, numbers) before installing the replacement unit.
8. Place the unit in the holder and fasten it in the original way.
9. Connect the connector(s) and check that the fuses are properly engaged.
10. Check that the wiring does not rub anywhere and is not under tension.
11. Connect the battery.
12. Turn on the ignition and verify that the system responds normally (no unusual messages related to the unit).
• 4) Post-assembly checks and test drive/function verification
  • Verify that pressure control-related lights/messages do not come on (if the car has this signal).
  • If diagnostics are available, perform a communication check and possible deletion of stored faults.
  • After a short drive, check again if the fault does not return.

  5) The most common assembly mistakes + how to avoid them

  • Exchanging a unit with a different number → always check the match against 9660499380 / 5430F6.
  • Damage to the pins in the connector → unlock the connectors gently and straight, without prying with force.
  • Not solving the cause (oxidation/moisture in the connector) → check and treat the contacts, possibly also the wiring.
  • Manipulation without disconnecting the battery → always disconnect the battery for control units, to minimize the risk of short circuits and damage to the electronics.

  Reasons why the part is damaged

  • Moisture and corrosion in connectors or around the unit, oxidation of pins and subsequent poor communication.
  • Voltage fluctuations (weak battery, bad charging, inappropriate battery disconnection/connection).
  • Mechanical damage to the connectors, falling part, cracks in the plastic or loose attachment.
  • Cabling fault (broken wires, poor contact) which may manifest as unit failure.
