Changed the fuel pump on 2002 rendezvous and battery radio is locked and car won't start


Did you check for fuel pressure with a fuel pressure gauge before replacing fuel pump ? Did you test for spark ? Is there compression . Is the security light lit on the instrument cluster ? anti-theft system stops injectors from working if a problem is present. You changed the battery ? Battery Disconnect or Replacement Problems

I have a 2002 bravada and when I was driving I turned radio off and now I have no windows,radio,locks,fuel gauge,oil gauge.checked fueses and they were ok,any suggestions?


Does it start an run ? Your best bet is to take it to a ASE certified repair shop ! All the things not working are controlled by the BCM body control module an are on the class 2 serial data bus , would be best to have hooked up to a factory scan tool to see if there are any DTC'S - diagnostic trouble codes stored . The instrument cluster gauge information comes from the PCM / ECM - engine computer over class 2 data bus .
The instrument panel cluster (IPC) displays the fuel level as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the fuel level percent. The fuel gage defaults to empty if:
The instrument panel cluster (IPC) displays the engine oil pressure as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the engine oil pressure. The engine oil pressure gage defaults to 0 psi (0 kPa) or below if:
The Body Control Module (BCM) performs multiple body control functions. The BCM can control devices directly connected to its outputs based on input information. The BCM evaluates this information and controls certain body control systems by commanding outputs on or off. The BCM control inputs can be:
?€¢
Sensors and switches that are directly connected to the BCM


?€¢
Class 2 serial data received from other control modules connected to the class 2 serial data link.

The BCM is also capable of controlling other vehicle systems that are not directly wired to the BCM. The BCM does this by sending specific messages on the class 2 serial data link. The control module capable of performing the required function will respond to the BCM message.
You best bet is to take it the dealer or a ASE certified repair shop !

My speedo, rev counter, fuel guage and temp guage have all stopped working on my 2002 focus 2.0 ltr ghia. All fuses are ok. Any ideas of what could be the problem ?


The instrument cluster is a hybrid electronic cluster (HEC) with two basic configurations, the base cluster and the optional instrument cluster. In addition to the two basic configurations, the SVT uses a modified optional cluster in combination with a separate oil pressure and oil temperature cluster. The base instrument cluster, optional instrument cluster and the oil pressure and oil temperature cluster receive and output information utilizing both hardwired circuitry and the standard corporate protocol (SCP) or the controller area network (CAN) communication network (2.3L only). It is very important to understand:
  • where the input originates from.
  • all the information necessary in order for a feature to operate.
  • which module(s) receive(s) the input or command message.
  • does the module which received the input control the output of the feature, or does it output a message over the SCP or CAN network to another module?
  • which module controls the output of the feature. Its more then likely you need a new instrument cluster.

Instrument panel went dead


Checked Every fuse in the fuse box (no small task).This includes #4 - Power point Instrument Panel, #14 - Day time running lamps (auto lamps doesn't work nor does auto lock), #27 - ignition switch run feed, #35 - Instrument Cluster, #41 - Instrument Cluster, #42 - Delayed Accessory, #45 - Ignition switch run/start feed, #102 - Door locks body security module, #103 - Ignition switch, #110 - Ignition switch, & #116 - Ignition switch. But I also check all other ones as well, they all register OK. AC panel & radio work. Turn signals work. Mileage does not work, trip computer does. So, basically, everything works except auto head-lights, auto locks, and the dash cluster (no MPH, RPM, mileage display, Fuel, Temp, Tran Temp, and Oil Pressure).
