Instrument cluster lights go on when driving

2004 PT Cruiser, Turbo Auto trans. 40 K - While driving check engine, traction off, air bag, alarm, brake, ABS, & oil pressure lights come on with gear selector indicator showing transmission in all gears.  Also radio shifts back and forth from CD to Sirius broadcasting and engine temperature gauge drops below "C". Some of these indicators go to normal while driving others may or may not be on with next start up.  Eventually all returns to normal, until next event.  Car runs and drives perfectly while this happens. I replaced upper engine mount during these events having no affect.

Re: Instrument cluster lights go on when driving

There is a campaign on a possible electrical problem that may be related to your problem. I was able to get the information from the Alldata information website, I listed it below.

November 2003

Dealer Service Instructions for:
Customer Satisfaction Notification No. C30
PCM Electrical Connector Seals

Effective immediately, all repairs on involved vehicles are to be performed according to this notification. Rapid Response Transmittal (RRT) # 03-014 is being cancelled. Those vehicles that have already had this repair performed, as determined by our warranty records, have been excluded from this notification.

Models

2004            (CS)          Chrysler Pacifica
2004            (DR)          Dodge Ram Pick Up (Built at St. Louis North (J) and Saltillo (G)
                              Assembly Plants equipped with a gasoline engine)
2004            (JR)          Dodge Stratus Sedan, Chrysler Sebring Sedan and
                              Convertible
2004            (KJ)          Jeep Liberty
2003-2004       (PT)          Chrysler PT Cruiser
2003            (RS)          Dodge Caravan and Chrysler Voyager (2.4L Engine Only)
2004            (RS)          Dodge Caravan/Grand Caravan, Chrysler Town & Country

NOTE : This notification applies only to the above vehicles built from June 15, 2003 through August 14, 2003 (MDH 0615XX through 0814XX).

IMPORTANT : Many of the vehicles within the above build period have already been inspected or repaired and, therefore, have been excluded from this recall.

IMPORTANT : Some of the involved vehicles may be in dealer vehicle inventory. Dealers should complete this repair on these vehicles before retail delivery. Dealers should also perform this repair on vehicles in for service. Involved vehicles can be determined by using the VIP inquiry process.

Subject

The Powertrain Control Module (PCM) electrical connector seal (one or all) on about 63,000 of the above vehicles may be out of place or "rolled". This could allow water to enter into the PCM. Water and the resulting corrosion inside of the connector can cause various electrical and driveability concerns.

Repair

The PCM electrical connector seals must be inspected. Connectors with a "rolled" seal must be disconnected and properly reconnected.

Parts Information

No parts are required to perform the service procedure. However, if water and/or corrosion are found inside of a connector, the PCM and/or wiring harness may require replacement. Dealers should reference the Mopar Parts Catalog for the appropriate replacement PCM and/or wiring harness part numbers, if necessary.

Very few vehicles are expected to require PCM and/or wiring harness replacement.

Alternate Transportation

Dealers should attempt to minimize customer inconvenience by placing the owner in a loaner vehicle if inspection determines that PCM and/or wiring harness replacement is required and the vehicle must be held overnight.

Completion Reporting and Reimbursement

Claims for vehicles that have been serviced must be submitted on the DIAL
System or on the DealerCONNECT Claim Entry Screen located on the Service
tab. Claims submitted will be used by DaimlerChrysler to record Customer
Satisfaction Notification service completions and provide dealer payments.

Re: Instrument cluster lights go on when driving

I have inspected and cleaned pcm electrical connectors and have found seals in good order. I have added ground cables from battery to body to engine. Block to ensure good ground. I can bring up the  following codes on odometer:
P0513 Incorrect Mobilizer Key
U0101 No Transmission Bus Message
U0155 No Cluster Bus Message
U0168 No Skim Bus Message
U110c No Fuel Level Bus Message
The car still runs fine. I am considering changing the PCM.

Re: Instrument cluster lights go on when driving

If you can get someone with a scanner and have them clear all of the codes. Write down all of the codes first for reference before you clear any codes then see if any of the codes come back and if the problem went away.

Sometimes when work is done on a computer system you can set a code by diagnosing problems. So see what happens and get back to us with your results.
