Diagnostic Procedure
• Start the engine, and observe air pressure gauge.
• When air pressure gauge reading is not greater than 0.4±0.025 MPa, low pressure warning
light should come on.
• When air pressure gauge reading is greater than 0.4±0.025 MPa, low pressure warning light
should go out.
Check whether low pressure warning light is always lighted up or does not come on.
Yes > (Always lighted up) go to step 1.
No > (Does not come on) go to step 3.
1. Checking for low pressure warning light signal circuit short
(a) Ignition switch: ON.
