Toyota RAV4 Service Manual: Inspection
- Inspect no. 1 Chain tensioner
- Check that the plunger moves smoothly when the ratchet pawl is raised with your finger.
- Release the ratchet pawl, then check that the plunger is locked in place by the ratchet pawl and does not move when pushed with your finger.
- Inspect chain sub-assembly
- Using a vernier caliper, measure the length of the 16 links with the chain fully stretched.
Maximum chain elongation: 122.6 Mm (4.827 In.)
If the chain elongation is greater than the maximum, replace the chain sub-assembly.
Hint:
Take the measurements at 3 or more places selected at random.
- Inspect no. 2 Chain sub-assembly
- Using a vernier caliper, measure the length of the 8 links with the chain fully stretched.
Maximum chain elongation: 52.4 Mm (2.063 In.)
If the chain elongation is greater than the maximum, replace the no. 2 Chain sub-assembly.
Hint:
Take the measurements at 3 or more places selected at random.
- Inspect chain tensioner slipper
- Using a vernier caliper, measure the tensioner slipper wear.
Maximum wear: 1.0 Mm (0.039 In.)
If the wear is greater than the maximum, replace the chain tensioner slipper.
- Inspect no. 1 Chain vibration damper
- Using a vernier caliper, measure the vibration damper wear.
Maximum wear: 1.0 Mm (0.039 In.)
If the wear is greater than the maximum, replace the no. 1 Chain vibration damper.
- Inspect crankshaft timing sprocket
- Wrap the chain around the timing sprocket.
- Using a vernier caliper, measure the timing gear diameter with the chain.
Minimum gear diameter (with chain): 51.6 Mm (2.031 In.)
Notice:
The vernier caliper must be in contact with the chain rollers when measuring.
If the gear diameter is less than the minimum, replace the chain sub-assembly and crankshaft timing sprocket.
- Inspect oil pump drive sprocket
- Wrap the chain around the drive sprocket.
- Using a vernier caliper, measure the drive gear diameter with the chain.
Minimum gear diameter (with chain): 48.2 Mm (1.898 In.)
Notice:
The vernier caliper must be in contact with the chain rollers when measuring.
If the gear diameter is less than the minimum, replace the no. 2 Chain sub-assembly and oil pump drive sprocket.
- Inspect oil pump drive shaft sprocket
- Wrap the chain around the drive shaft sprocket.
- Using a vernier caliper, measure the drive shaft gear diameter with the chain.
Minimum gear diameter (with chain): 48.2 Mm (1.898 In.)
Notice:
The vernier caliper must be in contact with the chain rollers when measuring.
If the gear diameter is less than the minimum, replace the no. 2 Chain sub-assembly and oil pump drive shaft sprocket.

Solenoid circuit
Description
This solenoid is turned on in accordance with signals from the skid control
ecu and controls the pressure
on the wheel cylinders to control the braking force.
The solenoid and solenoid relay are built into the abs and traction actuator.

Hint:
When pressing the switch for 0.3 Seconds or less, the roof
glass moves but auto operation does not operate.
Check auto operation
Turn the ignition switch on.
When the roof glass is fully closed, press the slide
open switch for 0.3 Seconds or more. Check that
