Test 1

WARNING: This page is about a different car, the 2017 Chevrolet Spark. However, it is still accessible from the selected car via links, so may be relevant.

Ignition/Vehicle & All vehicle systems - Off
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.
Disconnect the electrical connector: S79D Window Switch - Driver
Test for less than 10 Ω between the test points: Ground circuit terminal 1 & Ground
- If 10 Ω or greater
1. Ground Connection - Disconnect
2. Test for less than 2 Ω between the test points: Ground circuit terminal 1 @ Component harness & Ground Connection
  - If 2 Ω or greater - Repair the open/high resistance in the circuit.
  - If less than 2 Ω - Repair the open/high resistance in the ground connection.
- If less than 10 Ω
Ignition - On / Vehicle - In Service Mode
Verify a test lamp turns On between the test points: Ignition circuit terminal 3 & Ground
- If the test lamp does not turn On and the circuit fuse is OK
1. Ignition/Vehicle - Off & Remove - Test lamp
2. Test for less than 2 Ω between the test points: Ignition circuit terminal 3 & Output terminal @ F7DB Fuse
  - If 2 Ω or greater - Repair the open/high resistance in the circuit.
  - If less than 2 Ω - Verify the fuse is OK and there is voltage at the fuse.
- If the test lamp does not turn On and the circuit fuse is open
1. Ignition/Vehicle - Off & Remove - Test lamp
2. Test for infinite resistance between the test points: Ignition circuit terminal 3 & Ground
  - If less than infinite resistance - Repair the short to ground on the circuit.
  - If infinite resistance
3. Test for infinite resistance between the test points:
  - Control circuit terminal 4 & Ground
  - Control circuit terminal 5 & Ground
  - Control circuit terminal 6 & Ground
  - Control circuit terminal 7 & Ground
  - If less than infinite resistance - Repair the short to ground on the circuit.
  - If infinite resistance - Test or replace the component: S79D Window Switch - Driver
- If the test lamp turns On
Ignition/Vehicle - Off
Connect the electrical connector: S79D Window Switch - Driver
Disconnect the electrical connector: M74D Window Motor - Driver
Connect a test lamp between the test points: Control circuit terminal 1 & Control circuit terminal 2
Ignition - On / Vehicle - In Service Mode
Operate the component: Driver Left Front Window Switch
Verify the test lamp state:
- Not Pressed=Test lamp Off
- Pulled - Up=Test lamp On
- Pressed - Down=Test lamp On
- If not the specified state
1. Ignition/Vehicle - Off & Remove - Test lamp
2. Disconnect the electrical connector: S79D Window Switch - Driver
3. Ignition - On / Vehicle - In Service Mode
4. Test for less than 1 V between the test points:
  - Control circuit terminal 1 @ Component harness & Ground
  - Control circuit terminal 2 @ Component harness & Ground
  - If 1 V or greater - Repair the short to voltage on the circuit.
  - If less than 1 V
1. Ignition/Vehicle - Off
2. Test for infinite resistance between the test points:
  - Control circuit terminal 1 @ Component harness & Ground
  - Control circuit terminal 2 @ Component harness & Ground
  - If less than infinite resistance - Repair the short to ground on the circuit.
  - If less than infinite resistance
1. Test for less than 2 Ω between the test points:
  - {LHD} Control circuit terminal 1 @ Component harness & Terminal 4 @ Component harness
  - {LHD} Control circuit terminal 2 @ Component harness & Terminal 5 @ Component harness
  - {RHD} Control circuit terminal 1 @ Component harness & Terminal 6 @ Component harness
  - {RHD} Control circuit terminal 2 @ Component harness & Terminal 7 @ Component harness
    - If 2 Ω or greater - Repair the open/high resistance in the circuit.
    - If less than 2 Ω - Replace the component: S79D Window Switch - Driver
- If the specified state
Test or replace the component: M74D Window Motor - Driver
