Step 1:
Drain the automatic transmission (see, MR 370, Mechanical, 23A Automatic transmission, Oil change) and
remove the transmission housing (see, MR 370, Mechanical, 23A Automatic transmission, Hydraulic
distributor).
Check the continuity and insulation of the following connections on the internal wiring harness:
●Connection code 5LH, between components 119 and the pressure switch on clutch 3.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Are the continuity and insulation correct?
If YES, replace the pressure switch on clutch 3.
If NO, replace the internal wiring harness.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition, wait 1 minute and carry out a road test followed by another
check with the diagnostic tool.
