Fault table

Notes:
♦ All the possible faults which can be detected by the
automatic gearbox control unit -J237 and can be dis-
played by V.A.G 1552, are listed below according to
the fault code.
♦ If defective parts are displayed during read out of the
fault memory, check additional lines to the component
for short-circuit and line interruption according to the
Current Flow Diagram ⇒ Current Flow Diagrams, Fault
Finding, Electrics and Fitting locations.

One of these read-outs is displayed additionally for the related component.
2) First check plug connection for contact corrosion or water penetration, replace if necessary. If fault of solenoid valve
is displayed, pay particular attention to the plug connection at the gearbox between ribbon cable/slide valve body
and wiring harness.

Self-Diagnosis/Electrical Test
♦ If faults only occur occasionally or the fault memory
If after repair „No fault detected" is displayed, the self-diagnosis is completed.
If despite the performed self-diagnosis, the automatic gearbox does not shift free of in-
terference:
- Check control unit identification ⇒ page 01-5.
- In the event of problems repeat driving situation, at the same time read measured val-
ues in the measured value block and check all signals for plausibility ⇒ page 01-16.
- Check gearbox ⇒ page 37-6.
Possible cause of fault
Line interruption or short-circuit to
earth.
Solenoid valve 1 -N88 defective.
Line interruption or short-circuit to
earth.
Solenoid valve 2 -N89 defective.
Line interruption or short-circuit to
earth.
Solenoid valve 3 -N90 defective.
was not erased after fault elimination, then these faults
are displayed for a defined time as „sporadic occurring
fault" ⇒ Fault recognition of the gearbox control unit
page 01-2.
