Toyota RAV4 (XA40) 2013-2018 Service Manual: Diagnostic trouble code chart
If a dtc is displayed during the dtc check, check the circuit listed for the dtc in the table below (refer to the appropriate page).
Hint:
- When the srs warning light remains on and the normal system code is output, a decrease in the source voltage is likely to occur. This malfunction is not stored in the memory of the center airbag sensor. If the power source voltage returns to normal, the srs warning light will automatically go off.
- When 2 or more dtcs are indicated, the dtc with the lowest number appears first.
- If a dtc is not listed on the dtc chart, the center airbag sensor may have malfunctioned.
- In the case of any malfunctions concerning open circuits, shorts to ground, or shorts to b+ due to squibs, other dtcs may not be set. In this case, repair the malfunction currently indicated and then perform a malfunction diagnosis again.
Mark in the check mode column:
Dtc does
not correspond to check mode.
Dtc
corresponds to check mode.
- When dtc b1650/32 is set as a result of troubleshooting the supplemental restraint system (srs), perform troubleshooting for the occupant classification system.

Sleep operation failure of occupant classification ecu
Description
During sleep mode, the occupant classification ecu reads the condition of
each sensor while the ignition
switch is off.
In this mode, if the occupant classification ecu detects an internal
malfunction, dtc b1796 is output.

How to proceed with troubleshooting
Hint:
*: Use the intelligent tester.
Hint:
If the display indicates a communication fault in the tester,
inspect the dlc3.
Hint:
Record or print dtcs and freeze frame data, if necessary.

If the engine does not start, first perform the "check dtc"
procedures a ...
Pressure control solenoid "A " performance (shift solenoid valve sl1)
Description
The ecm uses signals from the vehicle speed sensor to detect the actual gear
position (1st, 2nd, 3rd or
o/d gear).
Then the ecm compares the actual gear with the shift schedule in the ecm memory
to detect mechanical
problems of the shift solenoid valves, valve body or automatic ...
