1. Check for other DTCs or temporary DTC indicated simultaneous with DTC P1898.
Are there any other DTCs?
YES- Perform the troubleshooting for the indicated DTC. Recheck for DTC P1898 after troubleshooting.
NO- Go to step 2.
2. Clear the DTC with the HDS.
3. Warm up the engine until the engine coolant temperature reaches 176°F (80°C).
4. Check the IMA battery level gauge in the gauge assembly.
Does the battery level gauge indicate 4 - 19 segments?
YES- Go to step 5.
NO- Run the engine in the P position at 3,500 rpm until the battery level gauge shows 4 - 19 segments, then go to step 5.

Is DTC P1898 indicated?
YES- CVT drive pulley pressure control valve or CVT driven pulley pressure control valve may be stuck. Replace the CVT drive pulley pressure control valve and the CVT driven pulley pressure control valve, then go to step 10.
NO- Return to step 6, and repeat test-drive. If the tester does not indicate DTC after the test-drive has been done four times, the problem is an intermittent failure; the system is OK at this time.
