Question about 2003 Chevrolet Malibu

1 Answer

I have a 2003 Malibu, 3.1 V6, 120K miles. Normally when I turn the ignition switch to on, all indicator warning lights and gas gauge work in the ip cluster. After a few seconds only the battery, check engine, theft system and gas are still operating. Also the heater fan and radio are operating since they were on previously. I can turn the switch to start and the car will start. Here's the intermittent problem: Sometimes only the theft light operates (along with fan and radio) when I turn the switch to on. The car won't start when I turn the switch to start. After 10 seconds or sometimes 60 seconds, all of the lights and gas gauge operate. I can then start the car. On two occasions, the lights and gauge operated only momentarily. I waited a little while and then everything operated and I was able to start the car. Do you have any suggestions on what is causing the problem and how to fix it? I don't think the battery and ignition switch are causing the problem.

Well Gary , you should have it checked for DTC'S - diagnostic trouble codes . Not at a part's store , thier diagnostic tool only checks engine computer codes ! Your vehicle has a number of control modules , PCM/ECM - engine , BCM - body , ABS , Air bag , the instrument cluster has a microprocessor inside , an can set DTC'S as well. But the only way to read codes in most of these modules is with a professional type scan tool . The warning lights come on when you turn the key on as a bulb check an to let you know those systems are functioning . Could be your instrument cluster is defective or a communication network problem , do you know what a serial data bus or communication network is ? This is what the control modules share information on . Your 03 chevy has the IPC bus for data transfer from the BCM to the IPC . U codes are communication error codes .

Faulty electrical connections or wiring may be the cause of intermittent conditions. Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
U2000
The IPC determines that the BCM transmitted data to the IPC is invalid for greater than 12 seconds. The IPC sends a message to the BCM via the SPI serial data in circuit indicating that invalid data was received.
U2001
The BCM determines that the IPC transmitted data to the BCM is invalid for greater than 5 seconds.
U2002
The BCM detects that the SPI serial data in circuit is less than 1.2 v for greater than 5 seconds.
U2003
The BCM detects that the SPI serial data in circuit is greater than 4.5 v for greater than 5 seconds.
U2004
The BCM detects that the SPI serial data out circuit is less than 1.2 v for greater than 5 seconds.
U2005
The BCM detects that the SPI serial data out circuit is greater than 4.5 v for greater than 5 seconds.
U2006
The BCM detects that the SPI serial data clock circuit is less than 1.2 v for greater than 5 seconds.
U2007
The BCM detects that the SPI serial data clock circuit is greater than 4.5 v for greater than 5 seconds.

Your vehicle also uses class 2 data bus .

Class 2 Serial Data Link
The class 2 serial data link allows the following modules to communicate with each other:
• The body control module (BCM)
• The electronic brake control module (EBCM)
• The integrated radio chassis (IRC)
• The powertrain control module (PCM)
• The Remote Control Door Lock Receiver (RCDLR)
• The inflatable restraint sensing and diagnostic module (SDM)
The class 2 serial data link allows a scan tool to communicate with the above modules for diagnostic and testing purposes.

SOURCE: where is the turn signal flasher located in the 1997 malibu?

You are looking for (typically) a cylindrical device 1-1 1/2 inches in diameter and 2-2 1/2 inches tall. These can be mounted in any position and often are pushed into a spring clip holder. Most have three male connectors although some may have only two.

SOURCE: intermittent starter operation, sometimes it starts fine,

First step is to clean the battery cables and battery posts next drive it to an auto shop and have them to test the battery and alt. output, this will eliminate those issues, next on the list is to test the battery cables to see if they are bad but that you need a test meter or strip off a half inch of insulation off the neg and the positive cable and see if you see white or green powder, if you do replace the cable, if this does not fix it you need to do a amp draw on the starter to see if the bearing are freezing up if that does not solve it let me know and I will help you fix the issue.

It likely had water on the ignition system. The check engine light will flash for misfire. The VSC light is on just because the check engine light is on. You likely have it dried out now and its fine. You just need to clear the codes. Autozone will do this for free.

Most of the warning lights and fuel gauge does not operate when the ignition switch is turned to on.


Given the complexity of your vehicle , all the control modules , serial data communication network. Having the vehicle scanned for DTC'S - diagnostic trouble codes , not a code reader or at a auto parts store . A professional type tool is need to pull codes from BCM - body computer , Instrument cluster .

Fuel Gage
The IPC displays the fuel level as determined by the PCM. The body control module (BCM) receives a class 2 message from the PCM indicating the fuel level percent. The BCM converts the fuel level percent into a percent gage deflection. The IPC receives a message from the BCM via the serial peripheral interface (SPI) indicating the requested gage position. The fuel gage defaults to E (empty) if:
• The PCM detects a malfunction in the fuel level sensor circuit.
• The BCM detects a loss of class 2 communications with the PCM.
• The IPC detects a loss of SPI communications with the BCM.
When the fuel level is less than a pre-determined value, the low fuel indicator illuminates.

Could have U- codes , communication network problems .

DTC U1000 and U1255

Modules connected to the class 2 serial data circuit monitor for serial data communications during normal vehicle operation. Operating information and commands are exchanged among the modules. When a module receives a message for a critical operating parameter, the module records the ID number of the module which sent the message for State of Health monitoring, Node Alive messages. A critical operating parameter is one which, when not received, requires that the module use a default value for that parameter. When a module does not associate an ID number with at least one critical parameter within about 5.5 seconds of beginning serial data communication, DTC U1000 or U1255 is set. When more than one critical parameter does not have an ID number associated with it, the DTC will only be reported once.
The table below list the modules on the Class 2 Serial Data Circuit that will set a U1000 or U1255 and should be actively communicating the previously described messages on the Class 2 Serial Data Circuit.

Could have connection issues at the BCM - body control module , lose ground . The BCM controls all the thing's your have problems with .
Turn Signal Lamps
When the turn signal switch is place in either the right or left turn position, the turn/hazard request circuit is pulled low, through a resistor. The body control module (BCM) uses the resistors to determine if the left or right turn signals have been requested. The BCM then supplies an ON-OFF voltage to the turn signal lamps and turn signal indicator on the selected side of the vehicle. The turn signals receive a ground at G101, G401, or G403.

When the ignition switch is turned to the ON position, the vacuum fluorescent (VF) display (radio) turns on at maximum brightness. When the park lamps are ON all incandescent back lighting turn ON at the dimming level indicated by the IP dimmer switch. At the same time all vacuum fluorescent (VF) displays dim to match the indicated dimming level. When the headlamp switch is placed in the PARK position, the park lamp supply voltage circuit provides an input to the body control module (BCM). The BCM then supplies voltage to the instrument panel dimmer switch through the instrument panel dimming lamps control circuit. The setting of the instrument panel dimmer switch determines the amount of voltage that the instrument panel dimmer switch supplies to the BCM through the instrument panel dimming lamps low reference circuit. The BCM then sends a pulse width modulated (PWM) voltage to all the interior lamps. All the vacuum florescent (VF) and incandescent back lighting lamps are provided a specific voltage and are then grounded. When the headlight switch is turned to the PARK or HEADLAMP position, all incandescent back lighting turn on at the dimming level indicated by the IP dimmer switch. When the IP dimmer switch is moved from MIN to MAX, all vacuum fluorescent (VF) displays, as well as all incandescent back lighting respond from Minimum intensity to maximum brightness in response to the IP dimmer switch.

Engine Coolant Indicator(s)
LOW COOLANT LEVEL
The IPC illuminates the low coolant warning indicator when any of the following occur:
• The BCM detects a low coolant level condition for at least 30 seconds. The IPC receives a class 2 message from the BCM requesting illumination.
• The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds .

The thing to do first would be to hook up a factory or professional type scan tool an check for Instrument cluster or BCM DTC'S - diagnostic trouble codes . Then checking connection 's at the BCM , testing power an grounds .

Hi Badrick

Firstly, try disconnecting both your battery connections, and with the battery disconnected, turn the ignition switch fully, 3- 4 times ( To just discharge the computers ) Then reconnect the battery cables (pos + ) first.
This usually cures your problem.

Good Luck
