Fiat cargo 1.9 d only starts after the negative lead as been disconected for 30 minutes

i'd get the OBD codes read as the ECU or PCM is storing codes preventing starting ,might just need clearing by the scanner but will tell you what sensor/switch is at fault

What is the problem on 2001 dodge caravan p1601

Hi Marvin, I'm glad to help! The 2001 Dodge Caravan does not have a code P1601. There's a code P1602 for PCM Not Programmed, but if that were the case the engine would not start and run. I suggest clearing the code and see if it comes back, if it does, then have the PCM Re-Programmed and see what happens. Hope this helps and have an awesome day Marvin.

Where is the diagnostic port located on a 2000 fiat marea

on a 99 2.0 model you will have 2 diagnostic ports. both of them will be the fiat 3 pin type.

to connect the 3 pin fiat connector to a 16 pin obd2 connector you need 4 lengths of wire. use 3 lengths of wire to connect the 3 pin connector to the obd connector. also use 1 length of wire for power to the obd connector.

on the 16 pin obd2 connector use the following pins
4- chassis ground (connect to ground on 3 pin connector, or any good chassis earth)
5- signal ground (connect to black wire pin on 3 pin connector)
7- k line (connect to white wire pin on 3 pin connector)
16- 12vDC (connect to battery positive terminal)

What is code p 1601

CHEVROLET DTC P1601 - Serial Comm. Problem With Device 1

The Powertrain OBD System Check prompts the technician to complete some basic checks and store the freeze frame and failure records data on the scan tool if applicable. This creates an electronic copy of the data taken when the fault occurred. The information is then stored on the scan tool for later reference.

The UART serial data circuit must be OK so the IPC can send the password XXXXX to the PCM. A DTC P1601 being set would indicate that the UART serial data circuit cannot be used to send information and causing the P1629 also.

An IPC theft deterrent DTC being set would indicate that the Passlock System is faulty and not sending a password XXXXX the PCM. Additional information can be found in Accessories and Optional Equipment / Antitheft and Alarm Systems. See Accessories and Optional Equipment\Antitheft and Alarm Systems

After any Passlock System parts have been replaced, the PCM must relearn the password XXXXX these components.

Replacement PCM's must be reprogrammed. Refer to the latest Techline information for programming procedures.

If no faults have been found at this point and no additional DTC's were set, refer to Diagnostic Aids for additional checks and information.

Hope helps (remember to rate this answer).
