If YES, and if the fault is still there, contact the Techline.
If NO, move on to step 4.
Stage 4:
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).
Disconnect the connector from component 754, measure the resistance of lock-up/brake 1 solenoid valve
(on the connector of the internal wiring harness of the transmission) between the following connections:
●Connection code 5BF.
●Connection code 5LW.
The resistance must be 5.3 ΩΩ Ω Ω
± 0.5 ΩΩ Ω Ω
at 20 ˚C.
Is the resistance correct?
If YES, move on to step 5.
If NO, move on to step 6.
Stage 5:
Measure the continuity and insulation of the following connections:
●Connection code 5BF.
●Connection code 5LW.
Between components R22 and the internal connector in the transmission.
Are the continuity and insulation correct?
If YES, contact the Techline.
If NO, replace the intermediate wiring harness between connector R22 and the internal connector in the
transmission.
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
