The Following Tech 2 values were recorded under the following conditions:

Ignition ON

    • Engine stopped, ignition in the ON position
    • Closed throttle
    • Transmission selector in the Park position
    • Engine and transmission at ambient temperature
    • Accessories are OFF
    • Brake pedal is not applied

Engine Running

    • Engine running
    • Closed throttle
    • Transmission selector in the Park position
    • Engine, transmission at normal operating temperature
    • Accessories are OFF
    • Brake pedal not applied

A number of data lists are provided, that can save time when diagnosing symptomatic conditions.
