• Undercharged Battery
• P/S control module
Step
Action YesNo
1 Was “EPS System Check” performed? Go to Step 2.Go to “EPS System
Check”.
2 Battery voltage check
1) Check circuit fuse for P/S control module.
2) If OK, measure voltage between positive battery terminal
and vehicle body ground with engine running.
Is voltage 10 V or more? Go to Step 3.
Check charging system
referring to “Generator
Test (Undercharged
Battery Check) in
Section 1J”.
3 P/S control module power supply circuit check
1) Check power supply circuit and ground circuit for P/S
control module referring to “P/S Control Module Power
Supply and Ground Circuit Check”.
Is check result in good condition? Substitute a known-
good P/S control
module and recheck.
Repair defective circuit.

StepAction YesNo
1 Circuit fuse check
1) Disconnect P/S control modu le connector with ignition
switch turned OFF.
2) Check for proper connection to P/S control module connector at “E49-1”, “E49-2” and “E52-1” terminals.
3) If OK, check “P/S” fuse and “IG1 SIG” fuse for blowing.
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.
