DLN-226 < DTC/CIRCUIT DIAGNOSIS > [TRANSFER: TX15B] P1817 ACTUATOR MOTOR 4. Turn ignition switch “ON”. (Do not start engine.) 5. Check voltage between transfer shift high and transfer shift low relay connector terminals and ground. Are the inspection results normal? YES >> GO TO 4. NO >> Check the following. If any items are damaged, repair or replace damaged parts. • Harness for short or open between transfer control unit harness connector terminal 27 and transfer shift high relay harness connector E44 terminal 2. • Harness for short or open between transfer control unit harness connector terminal 27 and transfer shift low relay harness connector terminal E43 terminal 2. 4. CHECK TRANSFER RELAY 1. Turn ignition switch “OFF”. (Stay for at least 5 seconds.) 2. Remove transfer shift high relay and transfer shift low relay. 3. Apply 12V direct current between transfer shift high and low relay terminals 1 and 2. 4. Check continuity between relay terminals 3 and 4, 3 and 5. Are the inspection results normal? YES >> GO TO 5. NO >> Replace the transfer shift high or low relay. 5. CHECK (1): HARNESS BETWEEN TRANSFER CONTROL UNIT AND TRANSFER SHIFT RELAY 1. Turn ignition switch “OFF”. (Stay for at least 5 seconds.) 2. Disconnect transfer control unit harness connector. 3. Remove transfer shift high relay and transfer shift low relay. 4. Check continuity between the following terminals. - Transfer control unit harness connector M165 terminal 42 and transfer shift high relay harness connector E44 terminal 1. - Transfer control unit harness connector M165 terminal 50 and transfer shift low relay harness connector E43 terminal 1. Also check harness for short to ground and short to power. Is there continuity? YES >> GO TO 6. NO >> Repair or replace damaged parts. 6. CHECK (2): HARNESS BETWEEN TRANSFER CONTROL UNIT AND TRANSFER SHIFT RELAY 1. Turn ignition switch “OFF”. (Stay for at least 5 seconds.) 2. Disconnect transfer control unit harness connector. 3. Remove transfer shift high relay and transfer shift low relay. Connector Terminal Voltage (Approx.) E44 2 - Ground Battery voltage E43 2 - Ground Battery voltage SDIA3385E Terminal Condition Continuity 3 - 4 12V direct current supply between terminals 1 and 2 No OFF Yes 3 - 5 12V direct current supply between terminals 1 and 2 Yes OFF No LDIA0099E Continuity should exist.
