DIAGNOSIS
Required Special Tools:
-
MB991223: Harness Set
-
MB992006: Extra Fine Probe
STEP 1. Check joint connector (CAN2) C-05, joint connector (CAN3) C-124 and intermediate connector C-128 for loose, corroded or damaged
terminals, or terminals pushed back in the connector.
CAUTION: The strand end of the twisted wire should be within 10 cm (4 inches) from the connector.
Q: Are joint connector (CAN2) C-05, joint connector (CAN3) C-124 and intermediate connector C-128 in good condition?
YES : Go to Step 2.
NO : Repair the damaged parts.
STEP 2. Check the wiring harness between joint connector (CAN2) C-05 and joint connector (CAN3) C-124.
CAUTION: Strictly observe the specified wiring harness repair procedure.
1. Disconnect joint connector (CAN2) C-05 and joint connector (CAN3) C-124, and check the wiring harness.
2. Check the wiring harness between joint connector (CAN2) C-05 (terminal 5) and joint connector (CAN3) C-124 (terminal 5)
3. Check the wiring harness between joint connector (CAN2) C-05 (terminal 16) and joint connector (CAN3) C-124 (terminal 16)
Q: Is the wiring harness between joint connector (CAN2) C-05 and joint connector (CAN3) C-124 in good condition?
YES : The trouble can be an intermittent malfunction (Refer to general (Body and Chassis), How to use Troubleshooting/inspection Service Points
How to Cope with Intermittent Malfunction).
NO : Repair the wiring harness between joint connector (CAN2) C-05 and joint connector (CAN3) C-124.
Diagnostic Item 11
DIAGNOSTIC ITEM 11: Diagnose when the scan tool cannot receive the data sent by KOS-ECU.
CAUTION: When servicing a CAN bus line, ground yourself by touching a metal object such as an unpainted water pipe. If you fail to do so, a
component connected to the CAN bus line may be damaged.
