Re-Programming PASM Control Unit

Information

Due to an allocation error involving the various vehicle-dependent data records for the PASM control unit, programming can be aborted in some cases when using the specified PIWIS Tester test software versions .

This allocation error is corrected with the updated test software version 33.700.010 or version 17.700.010 (which should be available from week 29/16).

Given this, if programming is aborted repeatedly on the affected vehicle, the control unit programming measure described here cannot be carried out using the currently available PIWIS Tester test software versions. In this case, control unit programming must be carried out again at a later time using the updated test software versions specified above.

Information

The procedure described here is based on the PIWIS Tester II software version 17.100.030 .

The PIWIS Tester instructions take precedence and in the event of a discrepancy, these are the instructions that must be followed. A discrepancy may arise with later software versions for example.

Work Procedure:

NOTE: Use of a PIWIS Tester software version that is older than the prescribed version

Measure is ineffective
1. Always use the prescribed version or a higher version of the PIWIS Tester software for control unit programming.

Re-program PASM control unit .
The basic procedure for control unit programming is described in the service information

> WM 9X00IN BASIC INSTRUCTIONS AND PROCEDURE FOR CONTROL UNIT PROGRAMMING USING THE PIWIS TESTER .

For specific information on control unit programming during this campaign, see table below.

Required PIWIS Tester software version:	PIWIS Tester 3:	33.010.030 (or higher)
	PIWIS Tester II:	17.100.030 (or higher)
Type of control unit programming:	Control unit programming using the "Campaign" function in the Additional menu on the PIWIS Tester by entering a programming code.
Programming code:	Q1X9X
Programming sequence:	Read and follow the information and instructions on the PIWIS Tester during the guided programming sequence. During the programming sequence, the PASM control unit is reprogrammed and then re-codedautomatically . Do not interrupt programming and coding.
Programming time (approx):	5 minutes
Data record (Porsche part number) programmed during this measure:	7P0907553AH 7P0907553AJ 7P0907553AK The Porsche part number of the programmed data record is vehicle-dependent and can be read out of the PASM control unit in the => 'Extended identification' menu using the PIWIS Tester following control unit programming.The Porsche part numbers specified above are the currently valid part numbers.
Procedure in the event of error messages appearing during the programming sequence:	> WM 9X00IN BASIC INSTRUCTIONS AND PROCEDURE FOR CONTROL UNIT PROGRAMMING USING THE PIWIS TESTER - section on "Fault finding" .
Procedure in the event of abnormal termination of control unit programming:	Repeat control unit programming by entering the programming code again. If programming is aborted repeatedly, see information below.
