Driver's MPCS Unit Input Test
- Turn the ignition switch to LOCK (0).
- Remove the driver's door panel (see FRONT DOOR PANEL REMOVAL/INSTALLATION ).
- Disconnect driver's MPCS unit connector A (40P).
- Inspect the connector and socket terminals to be sure they are all making good contact.
- If the terminals are bent, loose or corroded, repair them as necessary and recheck the system.
- If the terminals look OK, go to step 5.
- Reconnect the connector to the driver's MPCS unit, and do the following input tests.
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, go to step 6.
DTC TEST REFERENCE CHARTCavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained A5 BLK In all ignition switch positions Measure the voltage to ground: There should be less than 0.2 V. - Poor ground(G601)
- An open or high resistance in the ground wire
B14 BLK In all ignition switch positions Measure the voltage to ground: There should be less than 0.2 V. - Poor ground(G601)
- An open or high resistance in the ground wire
A7 WHT Under all conditions Measure the voltage to ground: There should be battery voltage. - Blown No. 15 (40 A) fuse in the under-hood fuse/relay box
- Blown No. 7 (10 A) fuse in the driver's under-dash fuse/relay box
- An open or high resistance in the wire
A25 YEL Ignition switch ON (II) Measure the voltage to ground: There should be battery voltage. - Blown No. 21 (10 A) fuse in the driver's under-dash fuse/relay box
- An open or high resistance in the wire
- Disconnect driver's MPCS connector A (40P), and do the following input tests.
- If any test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, the driver's MPCS unit must be faulty, replace it.
DTC TEST REFERENCE CHARTCavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained A8 GRY Under all conditions (Driver's under-dash fuse/relay box connector J (21P), power window master switch 6P connector, and moonroof motor/control unit 10P connector disconnected) Check for continuity between terminal A8 and driver's under-dash fuse/relay box connector J (21P) terminal No. 1, terminal A8 and power window master switch 6P connector terminal No. 6, and terminal A8 and moonroof motor/control unit 10P connector terminal No. 4: There should be continuity. An open or high resistance in the wire Check for continuity to ground: There should be no continuity. A short to ground in the wire A28 LT GRN Under all conditions (Driver's under-dash fuse/relay box connector J (21P) and AcuraLink control unit (XM receiver) connector A (32P) disconnected) Check for continuity between terminal A28 and driver's under-dash fuse/relay box connector J (21P) terminal No. 4, and terminal A8 and AcuraLink control unit (XM receiver)connector A (32P) terminal No. 10: There should be continuity. An open or high resistance in the wire Check for continuity to ground: There should be no continuity. A short to ground in the wire
