Was
A/T System Check
performed?
|
Go to Step 2.

Check Pressure Control Solenoid Circuit for IG Short
1)
Connect valve body harness connector.
2)
Disconnect TCM connectors.
3)
Check for proper connection to TCM at terminal “E121-2” and “E121-4” [A] or “E123-8” and “E123-11” [B].
4)
If connection is OK, turn ignition switch ON and measure voltage between terminal “E121-4” [A] or “E123-11” [B] of disconnected harness side TCM connector and ground.
Is it 0 – 2 V?

Go to Step 3.
|
“BLU/RED” or “BLU/YEL” circuit shorted to power circuit.

Check Pressure Control Solenoid Valve Resistance
1)
Turn ignition switch OFF.
2)
Disconnect valve body harness connector (1), (2) (harness side) on automatic transmission (3).
3)
Check for proper connection to solenoid at “BLU/RED” and “BLU/YEL” circuit.
4)
Check resistance of pressure control solenoid.
Resistance of check pressure control solenoid valve
Resistance between pressure control solenoid valve terminals of transmission side valve body harness connector: 5.0 – 5.6 Ω (at 20 °C (68 °F))
Resistance between pressure control solenoid valve terminals of transmission side valve body harness connector and transmission body: Infinity
Is check results satisfactory?
|
Intermittent trouble or faulty TCM. Check for intermittent referring to
Intermittent and Poor Connection Inspection
. If OK, substitute a known-good TCM and recheck.
|
Replace pressure control solenoid valve or valve body harness.
