INSPECTION PROCEDURE O-13: The speed sensor signal is not sent to the ETACS-ECU.: Diagnosis

WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.

Required Special Tools:

MB991223: Test Harness Set
MB991502: Scan Tool (MUT-II)
MB991529: Diagnostic Trouble Code Check Harness

STEP 1. Verify the speedometer operation.
Q: Does the speedometer work normally?

YES : Go to Step 2.

NO: Solve the problem first. Refer to COMBINATION METER .
STEP 2. Check the speed sensor connector B-109 < M/T > or power control module connector C-117 < A/T-2.4L > or C-119 < A/T-3.0L > and ETACS-ECU connector C-318 for loose, corroded or damaged terminals, or terminals pushed back in the connector.

Q: Are hazard warning light switch connector B-109 < M/T > or power control module connector C-117 < A/T-2.4L > or C-119 < A/T-3.0L > and ETACS-ECU connector C-318 in good condition?

YES : Go to Step 3.

NO: Repair or replace the damaged component(s). Refer to , HARNESS CONNECTOR INSPECTION . The speed sensor input signal should be able to be checked and the functions, which are described in the "TECHNICAL DESCRIPTION (COMMENT) ," should work normally.

NOTE: Also check intermediate connectors B-106 < M/T > and C-25 and joint connector C-140 for loose, corroded, or damaged terminals, or terminals pushed back in the connector. If intermediate connectors B-106 < M/T > or C-25 or joint connector C-140 are damaged, repair or replace the damaged component(s) as described in , HARNESS CONNECTOR INSPECTION .

Q: Are the wiring harness between speed sensor connector B-109 (terminal 3) < M/T > or power control module connector C-117 (terminal 80) < A/T-2.4L > or C-119 (terminal 80) < A/T-3.0L > and ETACS-ECU connector C-313 (terminal 63) in good condition?

YES : Replace the ETACS-ECU. The speed sensor input signal should be able to be checked and the functions, which are described in the "TECHNICAL DESCRIPTION (COMMENT) ," should work normally.

NO: The wiring harness may be damaged or the connector(s) may have loose, corroded or damaged terminals, or terminals pushed back in the connector. Repair the wiring harness as necessary. The speed sensor input signal should be able to be checked and the functions, which are described in the "TECHNICAL DESCRIPTION (COMMENT) ," should work normally.
