DTC Detecting Condition and Trouble Area






DTC Confirmation Procedure

WARNING:

- When performing a road test, select a place where there is no traffic or possibility of a traffic accident and be very careful during testing to avoid occurrence of an accident.
- Road test should be carried out with 2 persons, a driver and a tester.

NOTE:

Check to make sure that the following conditions are satisfied when using this DTC confirmation procedure.

- Intake air temp.: -14 °C, 6.8 °F or higher
- Altitude (barometric pressure): 2020 m, 6650 ft or less (540 mmHg, 72 kPa or more)

1) Turn OFF ignition switch and connect scan tool to DLC.
2) Clear DTC with ignition switch turned ON.
3) Start engine and shift select lever to "D" range.
4) Increase vehicle speed to higher than 25 mph, 40 km/h and then stop vehicle.
5) Repeat step 4 nine times.
6) Shift selector lever to "2" range and repeat step 4 and 5.
7) Shift selector lever to "L" range and repeat step 4 and 5.
8) Check DTC and pending DTC.

DTC Troubleshooting

1.
Was "Engine System Check" performed?
YES
Go to Step 3.
NO
Go to Engine System Check Engine System Check.

2.
Do you have SUZUKI scan tool?
YES
Go to Step 3.
NO
Go to Step 4.

3. PNP signal ("D" range signal) check

Connect SUZUKI scan tool to DLC with ignition switch OFF.
Turn ignition switch ON and check PNP signal ("P/N" or "D" range) on display when shifting select lever to each range.

SUZUKI Scan tool display
Selector lever position "P" and "N" range: P/N range
Selector lever position "R", "D", "2" and "L" range: D range

Is "D" range on display no matter which of "R", "D", "2" and "L" range positions select lever may be at?
YES
Intermittent trouble or faulty ECM.
Check for intermittent referring to Intermittent and Poor Connection Inspection.
NO
Go to Step 5.

4. PNP signal ("D" range signal) check

Turn ignition switch ON.
Check voltage at terminal "G04-14" of ECM connector connected.

Voltage at G07-28 terminal
Selector lever position "P" and "N" range: 10 - 14 V
Selector lever position "R", "D", "2" and "L" range: 0 - 1 V

Is 0 - 2.5 V indicated no matter which of "R", "D", "2" and "L" range positions select lever may be at?
YES
Intermittent trouble or faulty ECM.
Check for intermittent referring to Intermittent and Poor Connection Inspection.
NO
Go to Step 5.

5.
Is "P/N" range on display (Is 10 - 14 V indicated) when select lever is at one of "R", "D", "2" and "L" range positions only?
YES
Check transmission range sensor and circuits referring to Transmission Range Sensor (Shift Switch) Inspection and Adjustment.
NO
Go to Step 6.

6. PNP signal circuit check

Turn ignition switch OFF.
Disconnect TCM connectors (1).
Check for proper connection to TCM at terminal "G07-28".
If OK, then check voltage at terminal "G07-28" in TCM connector disconnected, with ignition switch ON.






Is it 10 - 14 V?
YES
"BRN/YEL" circuit open, poor "BRN/YEL" connection in Transmission range sensor harness connector, select cable maladjusted, transmission range sensor maladjusted or transmission range sensor malfunction.
If all results are OK, substitute a known-good TCM and recheck.
NO
"GRY/RED" circuit open or poor "G04-14" connection.
If wire and connection are OK, substitute a known-good ECM and recheck.
