Diagnosis & Testing: Notes

NOTE: Diagnostic unit for retrieving codes is located in right front section of engine compartment. Diagnostic unit is equipped with an LED indicator, activation button and function select cable. See Fig 1.

All fault codes contain 3 digits (example 3-1-1). Since codes have 3 digits, each code requires 3 series of flashes. A 3-second interval separates series of flashes. Ensure all testing and diagnosis is performed in the following order.
