Step 7:
Measure the continuity and insulation of the following connections:
●Connection code 5BF.
●Connection code 5LW.
Between lock-up/brake solenoid valve 1 and the internal connector on the transmission.
Are the continuity and insulation correct?
If YES, contact the Techline.
If NO, replace the internal wiring harness on the automatic transmission.
Step 8:
Check the continuity and insulation of the following connection:
●Connection code 5LW between components 119 and 754.
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.
If + after ignition feed is not present after checking feeds and earths on the transmission computer, contact the
Techline.
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
