Test D: No Communication With Rap Module

  1. Turn ignition switch to LOCK position. Check condition of instrument panel fuse block ROOM fuse (10-amp). On ZX2 coupe, check condition of instrument panel fuse block RADIO fuse (5-amp). On sedan and wagon, check condition of instrument panel fuse block MIRROR fuse (5-amp). On all models, if fuses are okay, reinstall fuses and go to step 4)  . If ROOM fuse is not okay, go to next step. If RADIO fuse (ZX2 coupe) or MIRROR fuse (sedan and wagon) is not okay, go to step 3)  .
  2. Disconnect RAP module Gray, 22-pin connector C404 (located in luggage compartment/trunk, behind right trim panel on ZX2 coupe and sedan, or located behind left rear quarter trim panel on wagon). Replace instrument panel fuse block ROOM fuse (10-amp). Check condition of replaced ROOM fuse. If fuse is okay, replace RAP module and retest system operation. If fuse is not okay, repair short to ground in Blue/Red wire between terminal No. 10 at Central Junction Box (CJB) harness connector C270 and terminal No. 12 at RAP harness connector C404.
  3. Disconnect RAP module Gray, 26-pin connector C405 (located in luggage compartment/trunk, behind right trim panel on ZX2 coupe and sedan, or located behind left rear quarter trim panel on wagon). On ZX2 coupe, replace instrument panel fuse block RADIO fuse (5-amp). On sedan and wagon, replace instrument panel fuse block MIRROR fuse (5-amp). Check condition of replaced fuses. If fuses are okay, replace RAP module and retest system operation. If fuses are not okay, repair short to ground in Blue/Black wire between terminal No. 8 at instrument panel fuse block harness connector C270 and terminal No. 25 at RAP module harness connector C405.
  4. Disconnect RAP module Gray, 22-pin connector C404 (located in luggage compartment/trunk, behind right trim panel on ZX2 coupe and sedan, or located behind left rear quarter trim panel on wagon). On 4-door remote system, check resistance between ground and terminal No. 14 (Black wire) at RAP module 22-pin connector C404. See Figure . On driver's door only remote system, check resistance between ground and terminal No. 24 (Black wire) at RAP module 26-pin connector C405 . See Figure . On all models, if resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open in Black wire between terminal No. 24 RAP module harness connector C405, joint connector C402 and ground G402 (both are located at left rear corner of luggage compartment).
  5. Using a voltmeter, check voltage between ground and terminal No. 12 (Blue/Red wire) at RAP module 22-pin connector C404. If battery voltage exists, go to next step. If battery voltage does not exist, repair open in Blue/Red wire between terminal No. 10 at CJB harness connector C270 and terminal No. 12 at RAP module harness connector C404.
  6. Disconnect RAP module Gray, 26-pin connector C405 (located in luggage compartment/trunk, behind right trim panel on ZX2 coupe and sedan, or located behind left rear quarter trim panel on wagon). Using a voltmeter, check voltage between ground and terminal No. 25 (Blue/Black wire) at RAP module 26-pin connector C405. See Figure . If battery voltage is present, go to TEST E: NO MODULE/NETWORK COMMUNICATIONS - ISO 9141 LINK MODULE COMMUNICATIONS NETWORK article to continue diagnosis. If battery voltage is not present, repair open in Blue/Black wire between terminal No. 8 at instrument panel fuse block harness connector C270 and terminal No. 25 at RAP module harness connector C405.
