2. Select the tester menus: OBD/MOBD, ENGINE, DATA LIST and A/T.
3. Check A/T OIL TEMP.
4. Allow the engine to idle until the fluid temperature reaches 46°C (115°F).
b. Without hand-held tester (Using D shift indicator)
1. Create a short circuit between CG (4) and TC (13) of the DLC3 terminals using SST (09843-
18040).
2. Move the shift lever back and forth between N and D at 1.5 seconds interval for six seconds.
3. The D shift indicator on the combination meter comes on for two seconds when the
combination meter begins to detect the fluid temperature.
4. The D shift indicator comes on again when the fluid temperature reaches 46°C (115°F) and
blinks when it exceeds 56°C (130°F).
c. For vehicles with air suspension (Using D shift indicator)
1. Create a short circuit between CG (4), OPA (11) and TC (13) of the DLC3 terminals using
SST (09843-18040).
2. Move the shift lever back and forth between N and D at 1.5 seconds interval for six seconds.
