Refer to
DIAGNOSIS CODE SET CONDITIONS
• Code No.32 is set when the steering wheel sen-
sor ST-N has been detected at the neutral posi-
tion in a state where the steering wheel has been
determined to have changed above 40
° from
steering wheel sensor ST-1 and ST-2.
• Code No.33 is set when the steering wheel sen-
sor ST-N has been detected at the neutral posi-
tion in a state where the steering wheel has been
determined to have changed above 400
° from
steering wheel sensor ST-1 and ST-2.
PROBABLE CAUSES
• Malfunction of the steering wheel sensor
• Damaged harness wires and connectors
• Malfunction of the 4WD-ECU
DIAGNOSIS
STEP 1. M.U.T.-II/III data list
Item 52: Steering wheel sensor <ST-N> (Refer to
data list reference table
).
Q: Is the check result normal?
YES :
Intermittent malfunction (Refer to GROUP
00
− How to Cope with Intermittent
NO :
Go to Step 2.
STEP 2. Measure the voltage at 4WD-ECU
connector C-26.
(1) Turn the ignition switch to the ON position.
(2) Measure the voltage between 4WD-ECU
connector C-26 terminal 44 and earth while
turning the steering wheel.
OK: Approximately 1.5
⇔ 3.5 V flushing
Q: Is the check result normal?
YES :
Go to Step 3.
NO :
Go to Step 5.
