Thermo King status lights
A trailer's status light is mounted where the driver can see it in the tractor mirror. Here's what it's telling you, and when to call your shop.
On a Precedent, the remote alarm light gives two signals.
Thermo King status light displays come in three options. All three show alarms.
Alarm codes and shutdown alarms.
“Monitor the status of the reefer unit.”
Everything Status Only shows, plus the fuel level, with a warning when fuel runs low.
Alarms, the fuel level and the temperature of one to three compartments.
“Monitor temperature, fuel level and status of the reefer unit.”
Add one: a remote status indicator light is an option on every T-90 Series truck unit, and status lights are an option on the Precedent S-750i. Your shop can find the right display and part number, and install it. See parts.
On a Precedent, that's a log alarm: the remote light stays on for 30 seconds at start-up, then goes off. One example is a maintenance hourmeter time-out. Find the code in the unit's alarm menu and look it up.
On a Precedent, that's a shutdown alarm: the unit shuts down and stays down until the alarm is manually cleared. Call your shop and read them the code. Service is 24/7. After hours, your shop's number reaches the on-call team, and mobile service trucks keep running.
Status Only shows alarms. Fuel Combo adds the fuel level. Triple Combo adds the temperature of one to three compartments.
