| Conditions for Setting the DTC |
10
The parking heater controller detects voltage greater than 15 V for at least 20 s without interruption.11
The parking heater controller detects voltage less than 10 V for at least 20 s without interruption.| Action Taken When the DTC Sets |
The parking heater will not operate.
| Conditions for Clearing the DTC |
| • |
This DTC will be current for as long as the fault is present.
|

| Circuit/System Verification |
Ignition OFF, command the parking heater ON and OFF with the remote control. Verify the parking heater turns ON and OFF with no DTCs.
| Circuit/System Testing |
| 1. |
Ignition OFF, separate the K87 Parking Heater Control Module from the X150 Parking Heater Harness & Parking Heater Assembly Harness.
|
|
| 2. |
Test for 10-15 V between harness connector terminal 1 and ground.
|
|
| 3. |
If not in the specified range, test power circuit for an open/high resistance.
|
|
| 4. |
Test for 10-15 V between harness connector terminal 1 and terminal 2.
|
|
| 5. |
If not in the specified range, test the ground circuit for an open/high resistance.
|
|
| 6. |
If all circuits test normal, replace the K87 Parking Heater Control Module.
