P/S Control Module Power Supply and Ground Circuit Check

Circuit Diagram










DTC Troubleshooting


1. Circuit fuse check
Confirm that the ignition mode of keyless push stat system is in "OFF".
Disconnect "E10" and "E11" connectors.
Check for proper connection to "E10-8" and "E11-1" terminals.
If connection are OK, check "P/S" fuse and "IG1 SIG" fuse for blowing.
Are they in good condition?
YES
Go to Step 2.
NO
Replace fuse(s) and check for short to ground in circuits connected to fuse(s).
2. P/S control module power supply circuit check
Check voltage between "E11-1" terminal and ground.
Is voltage 10 - 14 V?
YES
Go to Step 3.
NO
"A1" circuit is open.
3. IG1 power supply circuit check
Push engine switch to change ignition mode of keyless push start system to "ON".
Check voltage between "E10-8" terminal and ground.
Is voltage 10 - 14 V?
YES
Go to Step 4.
NO
"A2" circuit is open.
4. P/S control module ground circuit check
Push engine switch to change ignition mode of keyless push start system to "OFF".
Check resistance between "E11-2" terminal and ground.
Is resistance 1 or less?
YES
Go to Step 5.
NO
"A3" circuit is open or high resistance.
5. P/S control module ground circuit check
Connect "E10" and "E11" connectors.
Start engine.
Check voltage between "E11-2" terminal and ground when steering wheel fully turned to left or right.
Is voltage 0.5 V or less?
YES
"A1" and "A3" circuits are in good condition.
NO
"A3" circuit is open or high resistance.
