Diagnostic Trouble Code Chart
HINT:
- If any DTCs are displayed during the DTC check, inspect the circuit listed for those DTCs. For details of each DTC, refer to the page indicated in the DTC Chart below.
- Test mode code C1571/71 is stored during the transition to test mode. This code does not indicate a malfunction since the code will be cleared when the ECU determines that the sensor is normal. The test mode code is cleared simultaneously when test mode is terminated.
- The P/S warning light remains illuminated during test mode and starts blinking when the speed sensor is determined to be normal.
