Wiring Diagram
Refer to "DTC C1153: P/S Control Module Power Supply Circuit".
DTC Troubleshooting
Step
1 Circuit fuse check
1) Disconnect P/S control module connector with ignition
switch turned OFF.
2) Check for proper connection to P/S control module
connector at "E13-1", "E13-2" and "E11-1" 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?
2 Power supply circuit check
1) Measure voltage between "E13-1" terminal of P/S
control module connector and body ground.
Is voltage 10 – 14 V?
3 Ignition signal check
1) Turn ignition switch to ON position.
2) Measure voltage between "E11-1" terminal of P/S control
module connector and body ground.
Is voltage 10 – 14 V?
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 "E13-2" terminals of P/S
control module connector and body ground.
Ω
Is resistance 1 or less?
5 P/S control module ground circuit check
1) Connect connectors to P/S control module.
2) Start engine.
3) Measure voltage between "E13-2" terminals of P/S
control module connector and body ground when
steering wheel fully turned to left or right.
Is voltage 0.3 V or less?
Action Yes
Go to Step 2.
Go to Step 3.
Go to Step 4.
Go to Step 5.
