IGNITION SWITCH - ST AND TRANSAXLE RANGE(TR) SWITCH [A/T]
- When the ignition switch is set to the ST position, battery voltage is applied through the ignition switch and transaxle range switch to the ECM.
- If the selector lever is not in the P or N position, battery voltage will not reach the ECM.
- Based on this signal, the ECM determines the automatic transaxle load and drives the ISC motor to maintain optimum idle speed.

NOTE: If the TR switch harness check is normal but the TR switch output is abnormal, check for the control cable adjustment
