Test Point 5

TEST POINT 5
Solenoid valves 1, 2, 3 Open circuit/short to ground, short to B+

DTC 31, 32, 33

Fault Effect: Reduced driving program.

Note:
The functions of the solenoid valves (SVs) can be checked with the Porsche System Tester 2 (Drive links/Solenoid valves 1, 2, 3). The activation pulses of the valves can be heard as a clicking sound near the transmission.

1. Check function of the SVs with the Tester.

2. Check SV with wiring. To do this, connect ohmmeter to the control module connector and measure the resistance:

SV1 = Pin 52 and pin 30

5V2 = Pin 52 and pin 33

5V3 = Pin 52 and pin 32

Nominal value: 24 - 36 ohms

3. Check wiring from the control module connector pins 30, 32 and 33 to the 16-pole transmission connector pins 8, 4 and 9 for continuity, short to ground and short to B+.

4. Check SV. To do this, remove the ATF pan, disconnect plug connection on the SV and measure the resistance.

Nominal value: 24 - 36 ohms
