Pinpoint Test O : DTC B2486: Notes
Refer to Climate Controlled Seats for schematic and connector information.
Refer to Memory Seats for schematic and connector information.
Normal Operation and Fault Conditions
The SCME monitors the input voltage for correct operation. If the SCME detects input voltage below 10 volts or above 15 volts, it stores DTC B2486 in memory. If DTC B2486 is set, the SCME enters a standby mode and suspends operation of both seats until system voltage between 10 and 15 volts is restored and a climate controlled seat switch button is selected on.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B2486 | Climate Control Seat Module Voltage Out of Range |
NOTE:
DTC B2486 can be set if the vehicle has been recently jump started, the battery has been recently charged or the battery has been discharged. The battery may become discharged due to excessive load(s) on the charging system from aftermarket accessories or if the battery has been left unattended with the accessories on. If the SCME detects voltage below 10 volts or greater than 15 volts, the DTC is set. |
