General Description

Once IPM receives rear wiper switch working signal, it sends the signal to RAM by CAN communition. FAM operates rear wiper.

DTC Description

This code is set when RAM doesn't detect park signal within 5 sec. after rear wiper working.

DTC Detecting Condition

Item	Detecting Condition	Possible Cause
DTC Strategy	● Check voltage level	● Poor connection ● Faulty Rear Wiper motor
Enable Conditions	● IG KEY ON.
Threshold Value	● Park signal voltage - Wiper working: 12V - Wiper stop at Park position: 0V
Diagnostic Time	● 5 sec.
DTC Erasing Time	● DTC is erased immediately after trouble fixed.

Diagnostic Circuit Diagram

Scantool Data Analysis

Connect GDS.

IG "ON" and engine "OFF".

Select "DTC Analysis" mode.

After erase DTC, keep the vehicle condition within "the enable conditions" (Refer to "DTC Detecting Condition" table).

Is the same DTC occurred again?

	▶ Go to next procedure.
	▶ Fault is intermittent caused by poor contact in the sensor's and/or RAM's connector or was repaired and RAM memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.

■ Check Rear Wiper Motor

IG "OFF" and connect scantool

IG "ON" & ENG "OFF"

Select "Actuation Test" mode.

Execute "Rear Wiper Motor" test.

10.

Is the service data normal?

	▶ Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.
	▶ Go to next procedure.

Terminal and Connector Inspection

Many malfunctions in the electrical system are caused by poor harness(es) and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.

Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.

Has a problem been found?

	▶ Repair as necessary and go to "Verification of Vehicle Repair" procedure.
	▶ Go to "Rear Wiper Circuit Inspection" procedure.

Rear Wiper Circuit Inspection

■ Check short to ground in harness

IG "ON"

Measure the rear wiper motor position signal voltage of RAM.

Specification: Park signal voltage

- Wiper working: Approx. 12V

- Wiper stop at park position: Approx. 0V

Is the signal output normal?

▶ Substitute with a known - good FAM and check for proper operation.

If the problem is corrected, replace the FAM and go to "Verification of Vehicle Repair" procedure.

▶ Check open or short in circuit of rear wiper position singnal. Repair or replace as necessary and go to "Verification of Vehicle Repair" procedure.

Verification of Vehicle Repair

After a repair, it is essential to verify that the fault has been corrected.

Connect scan tool and select "DTC Analysis" mode.

Clear the DTCs and Operate the vehicle within DTC Enable conditions in General information.

Is any DTC outputted again?

	▶ Go to the applicable troubleshooting procedure.
	▶ System performing to specification at this time.
