On-Board Diagnostics System: Function
The on-board diagnostics system detects and stores in the form of a code a fault that has occurred in any of the following input and output signal systems.
If a fault has been detected, the system tells the fault by causing the AT OIL TEMP warning light to operate as follows:
- Repeated flashing at 4 Hz frequency ... Errors such as battery trouble
- Repeated flashing at 2 Hz frequency ... No faults in the system
- Flashing at different intervals and frequencies ... Diagnostic trouble codes of corresponding faults
- Continued illumination of light ... Fault in inhibitor switch, idle switch, or wiring
