Circuit/System Testing

NOTE:

It may take up to 2 min for all vehicle systems to power down before an accurate ground or low reference circuit continuity test can be performed.

Ignition/Vehicle & All vehicle systems - Off
Disconnect the appropriate electrical connector:A24D Door Handle Assembly - Driver ExteriororA24P Door Handle Assembly - Passenger Exterior
Test for less than 10 ohms between the test points:Ground circuit terminal 5 & Ground
- If 10 ohms or greater
1. Ground Connection - Disconnect
2. Test for less than 2 ohms between the test points:Ground circuit terminal 5@Component harness & Ground Connection
  - If 2 ohms or greater - Repair the open/high resistance in the circuit.
  - If less than 2 ohms - Repair the open/high resistance in the ground connection.
- Go to next step: If less than 10 ohms
Ignition - On / Vehicle - In Service Mode
Verify the scan tool parameter:Exterior Door Handle Switch Circuit=Inactive
- If not the specified state
1. Ignition/Vehicle - Off
2. Disconnect the electrical connector:X2@K84 Keyless Entry Control Module
3. Test for infinite resistance between the test points:Signal circuit terminal 1@Component harness & Ground
  - If less than infinite resistance - Repair the short to ground on the circuit.
  - If infinite resistance - Replace the component:K84 Keyless Entry Control Module
- Go to next step: If the specified state
Connect a 3 A fused jumper wire between the test points:Signal circuit terminal 1 & Ground circuit terminal 5
Verify the scan tool parameter:Exterior Door Handle Switch Circuit=Active
- If not the specified state
1. Ignition/Vehicle - Off & Remove - Jumper wire(s)
2. Disconnect the electrical connector:X2@K84 Keyless Entry Control Module
3. Ignition - On / Vehicle - In Service Mode
4. Test for less than 1 V between the test points:Signal circuit terminal 1@Component harness & Ground
  - If 1 V or greater - Repair the short to voltage on the circuit.
  - Go to next step: If less than 1 V
5. Ignition/Vehicle - Off
6. Test for less than 2 ohms between the test points:
  - Signal circuit terminal 1@A24D Door Handle Assembly - Driver Exterior & Terminal 12 X2@Control module harness
  - Signal circuit terminal 1@A24P Door Handle Assembly - Passenger Exterior & Terminal 11 X2@Control module harness
  - If 2 ohms or greater - Repair the open/high resistance in the circuit.
  - If less than 2 ohms - Replace the component:K84 Keyless Entry Control Module
- Go to next step: If the specified state
Test or replace the component:A24 Door Handle Assembly
