3.CHECK LAMP CIRCUIT
1. Turn ignition switch to “OFF” position.
2. Check resistance between TCM terminals 13 and 10, 19.
3. Reinstall any part removed.
OK or NG
OK >> GOTO4
NG >> Check the following items:
lO/D OFF indicator lamp.
Refer toDI-10, "
Meter/Gauge Operation and Odo/Trip
Meter Segment Check in Diagnosis Mode",
“METERS AND GAUGES”.
lHarness and fuse for short or open between ignition
switch and O/D OFF indicator lamp (Main harness)
Refer toPG-2, "
POWER SUPPLY ROUTING".
lHarness for short or open between O/D OFF indicator lamp and TCM.
4.CHECK SYMPTOM
Check again.
OK or NG
OK >>INSPECTION END
NG >> 1. Perform TCM input/output signal inspection.
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.
2. Engine Cannot Be Started In “P” and “N” PositionECS004V3
SYMPTOM:
lEngine cannot be started with selector lever in “P” or “N” position.
lEngine can be started with selector lever in “D”, “2”, “1” or “R” position.
1.CHECK PNP SWITCH CIRCUIT
With CONSULT-II
Does “TCM INPUT SIGNALS” in “DATA MONITOR” show damage to PNP switch circuit?
Wi th ou t C O N S U LT-I I
Does self-diagnosis show damage to PNP switch circuit?
Ye s o r N o
Yes >> Check PNP switch circuit. Refer to “21. TCM Self-diag-
nosis Does Not Activate (PNP& Overdrive Control
switches, and Throttle Position sensor Circuit Checks)”,
AT-382, "
