P/S CONTROL MODULE TROUBLESHOOTING FLOW CHART

Step Action YES NO
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 "C11-1" 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 "E13-1" terminal of P/S control module connector and body ground.

Is voltage 10 - 14 V? 
Go to Step 3. "GRN" or "WHT" wire is open circuit.
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? 
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 "E13-2" terminals of P/S control module connector and body ground.

Is resistance 1Ω or less? 
Go to Step 5. "BLK" wire is open or high resistance circuit.
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? 
P/S Control Module Power Supply and Ground Circuit is in good condition. "BLK" wire is high resistance circuit.
