TROUBLESHOOTING CHART

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 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?	Go to Step 3.	Replace TCC solenoid valve or lead wire.
3	Check TCC solenoid circuit for ground short Disconnect TCM connectors. Check for proper connection to TCM at terminal "G08-12" of TCM connector. If connection is OK, check continuity between terminal "G08-12" of disconnected harness side TCM connector and ground. Is continuity indicated?	"BLU/WHT" circuit shorted to ground.	Intermittent trouble or faulty TCM. Check for intermittent problem. If OK, substitute a known-good TCM and recheck.

Step

Action

Yes

Was "A/T System Check" performed?

Go to Step 2.

Check TCC solenoid valve resistance

Is check result satisfactory?

Go to Step 3.

Replace TCC solenoid valve or lead wire.

Check TCC solenoid circuit for ground short

Disconnect TCM connectors.
Check for proper connection to TCM at terminal "G08-12" of TCM connector.
If connection is OK, check continuity between terminal "G08-12" of disconnected harness side TCM connector and ground.

Is continuity indicated?

"BLU/WHT" circuit shorted to ground.

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