Step	Action	Yes	No
1	Was "A/T System Check" performed?	Go to Step 2.	Go to "A/T SYSTEM CHECK :".
2	Check TCC solenoid valve circuit for IG short Turn ignition switch ON and measure voltage between terminal "G08-12" of harness side TCM connector and ground. Is it 0 - 2 V?	Go to Step 3.	"BLU/WHT" circuit shorted to power circuit or open.
3	Check TCC solenoid valve resistance Turn ignition switch OFF. Disconnect valve body harness connector (1) on transaxle (3). Check for proper connection to solenoid at "BLU/WHT" circuit. Check resistance of solenoid. Resistance between terminal (2) of transaxle side valve body harness connector and transaxle 11 - 15 Ω (at 20°C (68°F)) Fig 1: Checking Resistance Between Terminal 2 Of Transaxle Side Valve Body Connector And Transaxle Courtesy of SUZUKI OF AMERICA CORP. Is check result satisfactory?	Intermittent trouble or faulty TCM. Check for intermittent problem. If OK, substitute a known-good TCM and recheck.	Replace shift solenoid valve or lead wire.

Step

Action

Yes

Was "A/T System Check" performed?

Go to Step 2.

Check TCC solenoid valve circuit for IG short

Turn ignition switch ON and measure voltage between terminal "G08-12" of harness side TCM connector and ground.

Is it 0 - 2 V?

Go to Step 3.

"BLU/WHT" circuit shorted to power circuit or open.

Check TCC solenoid valve resistance

Is check result satisfactory?

Intermittent trouble or faulty TCM. Check for intermittent problem. If OK, substitute a known-good TCM and recheck.

Replace shift solenoid valve or lead wire.
