Code p 1747 p1605 p600 - 1997 Mercedes-Benz E-Class

P1605 is a manufacturer specific code that means different things depending on which manufacturer's products it is applied to.

LDV began life as a BMC vehicle that became Leyland-Daf and later after they went into receivership LDV emerged as a management buyout. Since that time LDV vehicles have been fitted with various engines and other equipment, I understand Peugeot has been a supplier to them but I have lost touch with them.

I suggest you ask an LDV dealer about the code or discover who supplied the management system and use that information to check their codes.

Depends on model. http://www.obd-codes.com/p1605

These codes are indicating a starting problem and rough idling. Code p1604 is a very vague code and diagnosing it without having a symptom is very complicated. And code p1605 is rough idling which means that the computer have noticed a rough idle situation usually this code is accompanied by other codes or if it's alone then I would suspect a fuel pressure issue. These two codes involve diagnosis and we'll need to dig into this problem deeper to find out what's causing them, Unless you are an experienced technician who need assistance then I will suggest that you take your vehicle to your local toyota dealership and they should be able to find the problem.

OBD-II code P1603 indicates an issue with TCU communication.
There are communications that exist between the engine control module, or ECM, and the transaxle control module, or TCM. This communication is done through a control area network, or CAN. With the communication of the CAN, an independent pin and wiring is needed to receive a signal that includes sensor information from the ECM. The more information there is to communicate, the more wiring that is needed. When it comes to CAN communication, all of the information communicated is done alone control modules like the ECM and TCM using CAN lines. When there is a problem with these lines, the ECM will detect the problem and store a P1603 trouble code; the storing of the trouble code is what causes the SES or check engine light to illuminate on the dash.
Possible causes of trouble code P1603 include:

• Faulty transaxle control module (TCM)
• Faulty engine control module (ECM)
• Harness running from the TCM to the ECM has a short
• There is a poor electrical connection between the TCM and ECM

Diagnosing the exact cause of the problem should always begin with a visual inspection that could reveal bad wiring, loose connections, or damaged parts. From there, it is a matter of running down the list to determine what needs to be replaced. In general, a bad ECM will cause a loss of power, poor fuel economy, and stalling engine. While a bad TCM will have more prevalent transaxle issues like erratic shifting

P1P

would advise clearing code and see if comes back on ,may seem a bit of a funny way of working but many codes just flash a problem and then get stored in memory when theres no actual fault

go to www.aa1car.com and get the topics for OBII and fix it.
God bless you

P1605....Serial data communication problem with HVAC modul
P1775 Transmission system MIL fault
Go to the repair shop , for scanner and computer test.
The best (safest)way to erase trouble codes is to use a scan tool. The tool communicates with the vehicle computer and tells it to erase the codes. It does not alter any other learned settings that should be retained for normal vehicle operation.
The worst way to clear codes is to disconnect the battery. In most older vehicles (those made before 1996), disconnecting the battery even for a few seconds, or removing the power fuse for the engine computer (PCM) will erase the codes, along with all of the other learned settings the computer has stored over time.

Sir P600 is not a valid code, there needs to be 4 numbers in the code.

Hi, you have provided trouble codes p0100 AND p1605.

Trouble Code: P0100


Mass Airflow Sensor Circuit Malfunction
Possible Causes:



Air Intake leaks located after the MAF sensor assembly MAF sensor signal circuit is open, shorted to ground or power MAF sensor has failed PCM has failed

Trouble Code: P1605

A/T Diagnosis Communication Line Malfunction

Possible Causes:


TCM communication line circuit is open or shorted to ground TCM communication line circuit shorted to VREF or power (B+) TCM or PCM has failed TSB 01-004 (01/01) contains information related to this code
For the P0100, check the connector on top of the MAF sesnor for looseness or corrosion. Connector is on top in piocture below.
