Input Check (Galant With ETACS)

1. Use Multi-Use Tester (MB991341) to ensure input signals from switches are being sent to ETACS control unit.
2. Connect tester to diagnostic connector, located on left side kick panel, just right of fuse block. Turn ignition switch to ACC position.
3. Select appropriate test on tester. Tester should buzz once when each switch or sensor is activated. If buzzer sounds, switch or sensor signal is being sent to control unit.
4. If buzzer does not sound, a problem exists in that switch, sensor or wiring. Circuit(s) must be checked. (Scheme 16)- (Scheme 22). When checking vehicle speed sensor input, jack up front of vehicle and rotate tires in forward direction.

Power Supply & Ground Circuits

1. Check for battery voltage at terminal No. 36 at ETACS control unit harness connector. The battery supplies voltage to 5-volt power supply in control unit at all times. If necessary, repair power supply circuit. (Scheme 16)- (Scheme 20).
2. Disconnect ETACS control unit. Check continuity between control unit harness connector terminal No. 29 and ground, and between terminal No. 30 and ground. Continuity to ground should exist at both terminals at all times. If necessary, repair ground circuit(s).

Ignition Switch Input Circuit

1. Disconnect ETACS control unit. With ignition switch in ACC (accessory) position, check for battery voltage at control unit harness connector terminal No. 7. (Scheme 16)- (Scheme 20).
2. With ignition switch in OFF position, no voltage should be present at terminal No. 7. If voltage is not as indicated, check circuit and/or ignition switch. To check ignition switch, See appropriate STEERING COLUMN SWITCHES article in the ACCESSORIES/SAFETY EQUIPMENT Section.

Wiper Switch AUTO Input Circuit

1. Disconnect ETACS control unit. With wiper switch in OFF position, check continuity between control unit harness connector terminal No. 10 and ground. (Scheme 16)- (Scheme 20). No continuity should exist.
2. With wiper switch in AUTO position, check continuity between control unit harness connector terminal No. 10 and ground. Continuity should exist. If continuity is not as indicated, check circuit and/or wiper switch. To check wiper switch, See appropriate STEERING COLUMN SWITCHES article in the ACCESSORIES/SAFETY EQUIPMENT Section.

Intermittent Switch Input Circuit

1. Disconnect ETACS control unit. With intermittent (wiper) switch in FAST position, check resistance between control unit harness connector terminal No. 1 and ground. (Scheme 16)- (Scheme 20). Resistance should be zero (0) ohms.
2. Rotate intermittent switch to SLOW position while measuring resistance at terminal No. 1. Resistance should gradually increase to 1000 ohms as switch position changes. If resistance is not as indicated, check circuit and/or intermittent switch. To check intermittent switch, See appropriate STEERING COLUMN SWITCHES article in the ACCESSORIES/SAFETY EQUIPMENT Section.

Vehicle Speed Sensor Input Circuit

Disconnect ETACS control unit. Jack up front of vehicle. Rotate tires in forward direction while measuring continuity between control unit harness connector terminal No. 4 and ground. (Scheme 16)- (Scheme 20). Continuity should vary between continuity and NO continuity as tires rotate.

Note. Sensor sends 4 pulse signals, 0-8 volts for each rotation of transmission's output gear, to control unit terminal No. 4.

Wiper Relay Activation Circuit

1. With ignition switch and wiper switch in OFF position, check voltage between control unit harness connector terminal No. 27 and ground. (Scheme 21)and (Scheme 22). No voltage should exist.
2. With ignition switch in ACC position and wiper switch in OFF position, check voltage between control unit harness connector terminal No. 27 and ground. Battery voltage should exist. If voltage is not as indicated, check circuit and/or wiper relay activation circuit.
3. To check wiper relay, remove relay from firewall (next to wiper motor). Ensure continuity exists between relay terminal No. 2 and 5, and between terminal No. 1 and 3. (Scheme 21)and (Scheme 22).
4. Using jumper wires, connect battery positive terminal to relay terminal No. 3 and ground relay terminal No. 5. Ensure continuity exists between relay terminal No. 3 and 6. If relay continuity is not as indicated, replace wiper relay.

Washer Switch Input Circuit

1. With ignition switch and wiper/washer switch in OFF position, check voltage between control unit harness connector terminal No. 35 and ground. (Scheme 21)and (Scheme 22). No voltage should exist.
2. With ignition switch in ACC position and wiper/washer switch in ON position, check voltage between control unit harness connector terminal No. 35 and ground. Battery voltage should exist. If voltage is not as indicated, check circuit and/or wiper/washer switch. To check wiper/washer switch, See appropriate STEERING COLUMN SWITCHES article in the ACCESSORIES/SAFETY EQUIPMENT Section.

Checking Automatic Stop (Except Pickup, Precis & Ram-50)

1. Operate wiper motor at low speed. see scheme 11 Disconnect battery voltage during operation to stop motor.
2. Using a jumper wire, connect terminals as shown. see scheme 11 Connect 12 volts to indicated terminal, and ground wiper motor bracket. Ensure wiper arm is correctly parked.

Checking Automatic Stop (Pickup, Precis & Ram-50)

1. Operate wiper motor at low speed. See «CHECKING WIPER MOTOR OPERATION (PICKUP, PRECIS & RAM-50)»(ref-27114-S36056732702001010800000). Disconnect battery voltage to stop motor in any position except park.
2. Using a jumper wire, connect terminals indicated. See «AUTOMATIC STOP CHECK»(ref-27114-S01453365552001010800000). see scheme 12and see scheme 13. Connect 12 volts to terminal indicated in table, and ground wiper motor bracket. Ensure motor parks wiper arm.

AUTOMATIC STOP CHECK

Continuity & Voltage Check (Diamante)

1. Disconnect column switch connector. Turn wiper switch to OFF or AUTO position. Ensure continuity is present between terminals No. 3 and 10, and 1 and 12. Ensure there is no continuity between terminals No. 3 and 12.
2. Connect battery voltage to relay terminal No. 12 and ground terminal No. 1. Battery voltage should be present on terminal No. 3. Replace relay if continuity and voltage are not present. (Scheme 23)and (Scheme 24).
