B1828

B1828-TRUNK/GATE RELEASE CONTROL CIRCUIT







- When Monitored:
Continuously

- Set Condition:
When the Cluster senses a low or open condition on the (P31) Decklid/Liftgate Release Driver circuit during a release command for over 10 seconds, this code will set.





1. TEST FOR INTERMITTENT CONDITION
1. With the scan tool, record and erase DTC's
2. Operate the Liftgate or Decklid release several times.
3. Cycle the ignition from on to off.
4. Turn the ignition on.
5. With the scan tool, read DTC's.

Does the scan tool display B1828-TRUNK/GATE RELEASE CONTROL CIRCUIT PERFORMANCE?

Yes

- Go To 2

No

- The conditions that caused this code to set are not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
- Perform the BODY VERIFICATION TEST. Body Verification Test

2. (P31) DECKLID/LIFTGATE RELEASE DRIVER CIRCUIT SHORT TO GROUND




1. Turn the ignition off.
2. Disconnect the Instrument Cluster C1 connector.
3. Measure the resistance between ground and the (P31) Decklid/Liftgate Release Driver circuit in the Cluster C1 connector.

Is the resistance below 1.5 ohms?

Yes

- Repair the (P31) Decklid/Liftgate Release Driver circuit for a short to ground.
- Perform the BODY VERIFICATION TEST. Body Verification Test

No

- Go To 3

3. (P31) DECKLID/LIFTGATE RELEASE DRIVER CIRCUIT SHORTED TO BATTERY




1. Turn the ignition on.
2. Measure the voltage between ground and the (P31) Decklid/Liftgate Release Driver circuit in the Cluster C1 connector.

Is there any voltage present?

Yes

- Repair the (P31) Decklid/Liftgate Release Driver circuit for a short to voltage.
- Perform the BODY VERIFICATION TEST. Body Verification Test

No

- Go To 4

4. (P31) DECKLID/LIFTGATE RELEASE DRIVER CIRCUIT OPEN




1. Turn the ignition off.
2. Disconnect the Decklid/Liftgate Latch connector.
3. Measure the resistance of the (P31) Decklid/Liftgate Release Driver circuit between the Cluster C1 connector and the Decklid/Liftgate Latch connector.

Is the resistance above 5.0 ohms?

No

- Repair the (P31) Decklid/Liftgate Release Driver circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test

Yes

- Replace the Decklid or Liftgate Latch.
- Perform the BODY VERIFICATION TEST. Body Verification Test
