Mazda CX-5 Service & Repair Manual / Accessories / Storage / Low Engine Coolant Temperature Indicator Light (Blue)/High Engine Coolant Temperature Warning Light (Red)

Purpose

Low engine coolant temperature indicator light (blue)

High engine coolant temperature warning light (red)

Function

Low engine coolant temperature indicator light (blue)

High engine coolant temperature warning light (red)

Construction

Operation

Low engine coolant temperature indicator light (blue)

1. When the ignition is switched ON (while engine is running), the instrument cluster receives (1) the engine coolant temperature signal from the PCM via the CAN signal.

2. The instrument cluster turns the transistor on (2) based on the engine coolant temperature signal.

3. When the transistor turns on, the ground circuit of the low engine coolant temperature indicator light (blue) is established and the low engine coolant temperature indicator light (blue) illuminates (3).


High engine coolant temperature warning light (red)

1. When the ignition is switched ON (while engine is running), the instrument cluster receives (1) the engine coolant temperature signal from the PCM via the CAN signal.

2. The instrument cluster turns the transistor on (2) intermittently for flashing and continuously for illumination based on the engine coolant temperature signal.

3. The high engine coolant temperature warning light (red) flashes (3) when the transistor is turned on intermittently, and it illuminates (3) when the transistor is turned on continuously.
