DIAGNOSTIC FUNCTION AND JUDGEMENT CRITERIA
When the BSW-ECU (master) receives any invalid vehicle speed signal or any implausible
signal from the ASC-ECU, the ECU sets diagnosis code No.C2335.
PROBABLE CAUSES
- The ASC system fails
- Malfunction of BSW-ECU (master)
DIAGNOSIS PROCEDURE
STEP 1. Check the M.U.T.-III Diagnosis code for other
systems.
Check if diagnosis code is set in the ASC-ECU (Refer to GROUP 35C Troubleshooting - Diagnosis
Code Chart).
Q.
Is the diagnosis code set?
Troubleshoot the ASC-ECU.
Go to Step 2
STEP 2. Check whether the diagnosis code is set again.
Check again if the diagnosis code is set in the BSW-ECU (master).
|

Intermittent malfunction is suspected (Refer to GROUP 00 - How to Use
Troubleshooting/Inspection Service Points - How to cope with Intermittent Malfunction).
STEP 3. Check whether the diagnosis code is set again.
