PCM Reset Procedure

1. Make sure you have the anti-theft code for the radio, then write down the frequencies for the radio's preset buttons.

2. Turn the ignition switch OFF.

3. Remove the BACK UP, RADIO fuse (10 A) from the under-hood fuse/relay box for 10 seconds to reset the PCM.

NOTE: The PCM memory can also be cleared by using the OBD II Scan Tool or Honda PGM Tester.

Troubleshooting Precautions

ABS Indicator Light

1. If the system is OK, the ABS indicator light goes off two seconds after turning the ignition switch ON (II) without start-

ing the engine. After starting the engine, the ABS indicator light comes on again and goes off after two seconds. This

occurs because the ABS control unit is activated by the IG2 power source.

2. The ABS indicator light comes on when the ABS control unit detects a problem in the system. However, even though

the system is normal, the ABS indicator light comes on, too, under the following conditions. To determine the actual

cause of problem, question the customer about the problem, talking the following conditions into consideration.

Only drive wheels rotate

One wheel stuck of drive wheels

Vehicle spin

ABS operate condition continue for long time

Signal disturbance

3. When a problem is detected and the ABS indicator light comes on, there are cases when the indicator light stays on

until the ignition switch is turned OFF, and cases when the indicator light goes off automatically when the system

returns normal. For the DTC 61 and 62, the indicator light goes off automatically when the system returns normal. For

all other codes, the indicator light stays on until the ignition switch is turned OFF.

4. For DTCs 12, 14, 16, 18, 21, 22, 23, 24, 51, 52 and 53, the indicator light goes off when the vehicle is driven again and

the signals are OK after the ignition switch is turned from OFF to ON (II). However, if the DTC is erased, the CPU is

reset and the indicator light goes off right after the engine is started if the signals are OK.

Diagnostic Trouble Code (DTC)

1. The DTC is not memorized if the CPU cannot be activated or the CPU fails and the indicator light comes on.

2. The memory can hold any number of DTCs. However, when the same DTC is detected more than once, the later one

is written over the old one. Therefore, when the same problem is detected repeatedly, it is memorized as one DTC.

3. The DTCs are indicated in the order of ascending number, not in the order they occur.

4. The DTCs are memorized in the EEPROM (non-volatile memory). Therefore, the memorized DTCs cannot be canceled

by disconnecting the battery. Perform the specified procedures to erase the DTCs.

Self-diagnosis

1. The
self-diagnosis
can be
classified
into
two
categories.

• Initial diagnosis: Performed right after the engine starts and until the ABS indicator light goes off.

• Regular diagnosis: Performed right after the initial diagnosis until the ignition switch is turned OFF.

2. When a problem is detected by self-diagnosis, the system

• Turns the ABS indicator light ON

• Memorizes the DTC

• Turns the fail-safe relay OFF

• Stops ABS controlProCarManuals.com

Starter Solenoid Test

1. Make sure you have the anti-theft code for the

radio, then write down the frequencies for the

radio's preset buttons.

2. Disconnect the battery negative cable, then discon-

nect the positive cable.

3. Check the hold-in coil for continuity between the S

terminal and the armature housing (ground). The

coil is OK if there is continuity.

4. Check the pull-in coil for continuity between the S and

M terminals. The coil is OK if there is continuity.
