Toyota Yaris: Smart Key System (for Start Function) / Crankshaft Position Sensor "A" Signal Compare Failure (P033562)
DESCRIPTION
These DTCs are stored when the engine speed signal sent by the ECM via direct line and the engine speed signal sent via CAN communication do not match.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area | Note |
P033562 | Crankshaft Position Sensor "A" Signal Compare Failure | The engine speed signal sent by the ECM via direct line and the engine speed signal sent via CAN communication do not match. (1-trip detection logic*) | -
SFI system
-
Certification ECU (smart key ECU assembly)
-
Wire harness or connector
| -
Allow the engine to idle for 10 seconds or more, and then engine speed of 1000 rpm or more for 20 seconds or more.
|
-
*: Only detected while a malfunction is present and the ignition switch is ON.

-
When a malfunction occurs and the vehicle speed signal sent via either direct line or CAN communication indicates no vehicle speed, there is no effect on vehicle behavior. (A malfunction is detected after the ignition switch is turned to ON.)
-
When a malfunction occurs and the vehicle speed signal sent via either direct line or CAN communication indicates that the vehicle is moving, the engine cannot be started. However, the engine can be started after the ignition switch has been turned off.
| -
When a malfunction occurs and the vehicle speed signal sent via either direct line or CAN communication indicates no vehicle speed, there is no effect on vehicle behavior.
-
When the signal sent via either direct line or CAN communication is malfunctioning and indicates that the vehicle is moving:
If the following conditions are met, it can be determined that the malfunction is not in the CAN communication system but in the direct line (NE). -
When the engine switch is pressed, the system controls the engine based on the starter OFF permission flag (perfect injection signal judgment) via CAN communication, causing the engine to stop cranking.
-
When the engine switch is pressed and held, the system controls the engine based on the engine speed signal via CAN communication, causing the engine to stop cranking.
If the following conditions are met, it can be determined that the malfunction is not in the direct line (NE) but in the CAN communication system. -
When the engine switch is pressed, the system controls the engine based on the engine speed signal via direct line, causing the engine to stop cranking.
-
When the engine switch is pressed and held, the system controls the engine based on the engine speed signal via direct line, causing the engine to stop cranking.
If the following conditions are met, it can be determined that there is a malfunction in both the CAN communication system and the direct line (NE). -
When the engine switch is pressed, the engine stops cranking after 6 seconds.
-
When the engine switch is pressed and held, the engine cranks for up to 30 seconds.

CAUTION / NOTICE / HINT
NOTICE:
-
When using the GTS with the ignition switch off, connect the GTS to the DLC3 and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the GTS and the vehicle begins. Then select the vehicle type under manual mode and enter the following menus: Body Electrical / Smart Key. While using the GTS, periodically turn a courtesy light switch on and off at intervals of 1.5 seconds or less to maintain communication between the GTS and the vehicle.
-
The smart key system (for Start Function) uses the LIN communication system and CAN communication system. Inspect the communication function by following How to Proceed with Troubleshooting. Troubleshoot the smart key system (for Start Function) after confirming that the communication systems are functioning properly.

2. | CHECK HARNESS AND CONNECTOR (CERTIFICATION ECU (SMART KEY ECU ASSEMBLY) - ECM) |
(a) Disconnect the H45 certification ECU (smart key ECU assembly) connector.
(b) Disconnect the A106 ECM connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
H45-15 (NE) - A106-16 (NEO) | Always | Below 1 Ω |
H45-15 (NE) or A106-16 (NEO) - Other terminals and body ground | Always | 10 kΩ or higher |
NG |
| REPAIR OR REPLACE HARNESS OR CONNECTOR |
OK |
| |
3. | CHECK CERTIFICATION ECU (SMART KEY ECU ASSEMBLY) |
(a) Connect the H45 certification ECU (smart key ECU assembly) connector.
(b) Connect the A106 ECM connector.
(c) Using an oscilloscope, check the engine speed input signal waveform at the terminal of the certification ECU (smart key ECU assembly). OK: Tester Connection | Condition | Specified Condition | H45-15 (NE) - Body ground | Engine stopped | No pulse generation | Engine running | Pulse generation | |
| *a | Component with harness connected (Certification ECU (Smart Key ECU Assembly)) | | |
