Component Testing

S13 Door Lock Switch - Test

1. Ignition/Vehicle - Off
2. Disconnect the appropriate electrical connector: S13 Door Lock Switch
3. Test for infinite resistance between the test points:
   • Signal terminal 2 & Ground terminal 4 - Lock Switch - Not Pressed
   • Signal terminal 3 & Ground terminal 4 - Unlock Switch - Not Pressed
   • If less than infinite resistance 

     Replace the component: S13 Door Lock Switch

   • Go to next step: If infinite resistance 
4. Test for less than 3 ohms between the test points: Signal terminal 2 & Ground terminal 4 - Lock Switch - Pressed
   • If 3 ohms or greater 

     Replace the component: S13 Door Lock Switch

   • Go to next step: If less than 3 ohms 
5. Test for less than 3 ohms between the test points: Signal terminal 3 & Ground terminal 4 - Unlock Switch - Pressed
   • If 3 ohms or greater 

     Replace the component: S13 Door Lock Switch

   • Go to next step: If less than 3 ohms 
6. All OK.

A23 Door Latch Assembly

1. Ignition/Vehicle - Off
2. Disconnect the appropriate electrical connector:
   • A23D Door Latch Assembly - Driver
   • A23P Door Latch Assembly - Passenger
3. Connect a 25 A fused jumper wire between the test points:
   • A23D Door Latch Assembly - Driver: Control terminal 7 & B+
   • A23P Door Latch Assembly - Passenger: Control terminal 9 & B+
CAUTION:

Complete the testing as quickly as possible in order to prevent overheating and damaging the component.

4. Momentarily connect a jumper wire between the test points: Control terminal 8 & Ground
5. Reverse the jumper wires 2 times between the terminals.

   Verify the component works as specified: A23 Door Latch Assembly = Lock & Unlock

   • If not the specified state 

     Replace the component: A23 Door Latch Assembly

   • Go to next step: If the specified state 
6. All OK.
