Second Gear Start Switch

Second Gear Start Switch Circuit:

Purpose:
The Second gear switch enables the operator to accelerate in 2nd gear.

Operation:
When 2nd gear start is selected, the 2nd gear start switch input signal is momentarily toggled to zero volts. The PCM then turns "ON" the 2nd gear start mode indicator lamp and de-energizes the 1-2 shift solenoid enabling 2nd gear.

During light and medium acceleration conditions the vehicle will start in 2nd gear when selected. Second gear starts will be overridden and first gear starts will occur if a hard acceleration condition (WOT) is required.

Normal 1st gear start mode is obtained by toggling the 2nd gear start switch again, or when the ignition switch is cycled "OFF" and "ON".
