Inspection Procedure O-8

Rear Wiper Motor Auto-stop Input Circuit:




Connectors:






CIRCUIT OPERATION
The ETACS-ECU operates the rear wiper according to the input signal from the rear wiper motor auto-stop signal.

TECHNICAL DESCRIPTION (COMMENT)
Rear wiper motor auto-stop signal is used to operate the rear wiper. If the signal is an error, the rear wiper will not stop at the predetermined park position.

TROUBLESHOOTING HINTS
- Malfunction of the rear wiper motor
- Malfunction of the ETACS-ECU
- Damaged harness wires or connectors

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

STEP 1. Check the rear wiper operation.
If the rear wiper motor does not work at all, check the rear wiper motor drive circuit. Refer to Inspection Procedure H-1.
If the rear wiper motor works (but the rear wiper does not stop at the predetermined park position), go to Step 2.




STEP 2. Check the rear wiper motor.
1. Disconnect the rear wiper motor connector F-07.
2. Run the rear wiper motor, disconnect the battery, and stop the motor.
3. Reconnect the battery as shown in the illustration, and confirm that after the motor starts turning it stops at the automatic stop position.
If the rear wiper motor is damaged, replace the rear wiper motor.
The rear wiper motor auto-stop signal should be able to be checked and the rear wiper should stop at the predetermined park position.
If the rear wiper motor is in good condition, go to Step 3.




STEP 3. Check the rear wiper motor power supply circuit at the wiper motor connector F-07.
1. Disconnect the rear wiper motor connector F-07 and measure at the harness side.
2. Turn the ignition switch to "ACC" position.
3. Voltage between terminal 1 and ground.
- Voltage should be approximately 12 volts (battery positive voltage).
If not approximately 12 volts, go to Step 4.
If approximately 12 volts, go to Step 6.




STEP 4. Check the rear wiper motor connector F-07 for damage.
If the rear wiper motor connector F-07 is damaged, repair or replace it. Refer to Harness Connector Inspection.
The rear wiper motor auto-stop signal should be able to be checked and the rear wiper should stop at the predetermined park position.
If the connector is in good condition, go to Step 5.













STEP 5. Check the harness wires between rear wiper motor connector F-07 and ignition switch (ACC).

NOTE: After checking intermediate connector F-24 and junction block connectors C-101 and C-113, check the wires. If intermediate connector F-24 and junction block connectors C-101
and C-113 are damaged, repair or replace them. Refer to Harness Connector Inspection.

If the harness wires between rear wiper motor connector F-07 and ignition switch (ACC) are damaged, repair them. The rear wiper motor auto-stop signal should be able to be checked and the rear wiper should stop at the predetermined park position.







STEP 6. Check the rear wiper motor connector F-07 and ETACS-ECU connector C-114 for damage.
If the rear wiper motor connector F-07 and ETACS-ECU connector C-114 are damaged, repair or replace them. Refer to Harness Connector Inspection.The rear wiper motor auto-stop signal should be able to be checked and the rear wiper should stop at the predetermined park position.
If the connectors are in good condition, go to Step 7.










STEP 7. Check the harness wires between rear wiper motor connector F-07 and ETACS-ECU connector C-114.

NOTE: After checking intermediate connector F-24 and junction block connector C-113, check the wires. If intermediate connector F-24 and junction block connector C-113 are damaged, repair or replace them. Refer to Harness Connector Inspection.

If the harness wires between rear wiper motor connector F-07 and ETACS-ECU connector C-114 are damaged, repair them.
The rear wiper motor auto-stop signal should be able to be checked and the rear wiper should stop at the predetermined park position.
If the harness wires are in good condition, replace the ETACS-ECU.
The rear wiper motor auto-stop signal should be able to be checked and the rear wiper should stop at the predetermined park position.
