Transmission Shift Position Indicator Lamp: Testing and Inspection
System Inspection
SHIFT-UP INDICATOR LIGHT CONTROL SYSTEM (If equipped)
NOTE: Shift-up indicator light and duty output (terminal) are controlled by ECM through the same ECM terminal. If shift-up indicator light becomes
bright and dim repeatedly, check the diag. switch circuit and/or test switch circuit for grounding to the body.
WARNING: This check requires test drive. Use special care for safety when driving.
1. Turn ignition switch ON, and shift-up indicator light should light. If not, cause may be burned bulb, open wire, poor connection or faulty ECM.
Proceed to "Shift-up indicator light and its circuit inspection".
2. Start engine, and shift-up indicator light should go off. If not, cause may be shorted wire to ground or faulty ECM.
3. Warm up engine to normal operating temperature.
4. With gear shift lever in low gear position, increase engine speed. When it exceeds 1,600 r/min., shift-up indicator light should light for 5 seconds
at the longest.
If it doesn't light, check VSS, ECT sensor and MAP sensor. If they are all in good condition, substitute a known-good ECM for existing one.
