  4. If connection are OK, check "P/S" fuse and "IG1 SIG" fuse for blowing.

Are they in good condition? 		 Go to Step 2. Replace fuse(s) and check for short to ground in circuits connected to fuse(s).
2  P/S control module power supply circuit check 
  1. Check voltage between "E11-1" terminal and ground.

Is voltage 10 - 14 V? 		 Go to Step 3. "A1" circuit is open.
3  IG1 power supply circuit check 
  1. Push engine switch to change ignition mode of keyless push start system to "ON".
  2. Check voltage between "E10-8" terminal and ground.

Is voltage 10 - 14 V? 		 Go to Step 4. "A2" circuit is open.
4  P/S control module ground circuit check 
  1. Push engine switch to change ignition mode of keyless push start system to "OFF".
  2. Check resistance between "E11-2" terminal and ground.

Is resistance 1 Ω or less? 		 Go to Step 5. "A3" circuit is open or high resistance.
5  P/S control module ground circuit check 
  1. Connect "E10" and "E11" connectors.
  2. Start engine.
  3. Check voltage between "E11-2" terminal and ground when steering wheel fully turned to left or right.

Is voltage 0.5 V or less? 		 "A1" and "A3" circuits are in good condition. "A3" circuit is open or high resistance.
