Are “P/S” fuse and “IG1 SIG” fuse in good condition? Go to Step 2.
Replace fuse(s) and
check for short in
circuits connected to
fuse(s).
2 Power supply circuit check
1) Measure voltage between “E49-1” terminal of P/S
control module connector and body ground.
Is voltage 10 - 14 V? Go to Step 3.
“GRN” or “BLK” wire is
open circuit.
3 Ignition signal check
1) Turn ignition switch to ON position.
2) Measure voltage between “E52-1” terminal of P/S
control module connector and body ground.
Is voltage 10 - 14 V? Go to Step 4.
“LT GRN/BLK” or “GRN”
wire is open circuit.
4 P/S control module ground circuit check
1) Turn ignition switch to OFF position.
2) Disconnect connectors from P/S control module.
3) Measure resistance between “E49-2” terminals of P/S
control module connector and body ground.
Is resistance 1
Ω or less? Go to Step 5. “BLK” wire is open or
high resistance circuit.
