Diagnosis ProcedureINFOID:0000000005397330
1.CHECK INPUT SIGNALWith CONSULT-III
1. Turn ignition switch ON. (Do not start engine.)
2. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.
3. Read out the value of “LINE PRES DTY” while driv ing. Check the value changes according to driving
speed.
Without CONSULT-III
1. Turn ignition switch ON. (Do not start engine.)
2. Check voltage between TCM connector terminals and ground.
OK or NG
OK >> GO TO 5.
NG >> GO TO 2.
2.CHECK DROPPING RESISTOR
1. Turn ignition switch OFF.
2. Disconnect dropping resistor har ness connector in engine room.
3. Check resistance between terminals.
OK or NG
OK >> GO TO 3.
NG >> Repair or replace damaged parts.
3.CHECK VALVE RESISTANCE
1. Turn ignition switch OFF.
2. Disconnect terminal cord assembly connector in engine room.
