4) Check for voltage between “E51-1” (“BLK” wire) terminal
and body ground and “E51-2” (“RED” wire) terminal and
body ground with connector (“E51”) connected to the P/
S control module.
Are they 5 – 7 V with steering wheel at straight position?
Go to Step 4. Repair poor connection,
high resistance, open or
short to power circuit or
ground in “E51-1”
