Inspeclthe a utomatic transmission problem (s)accordingto the DTC (s)indicated with code m700.
(DTC)*: The DTCS in the parentheses are the codes the E indicator light indicates (blinks) when the service cnecK connec-tor is connected with the sDecialtool {SCS service connector).
NOTE: WhentheOBDll Scan Tool orHonda PGM Tester indicates the DTC(S) for the automatic transmission control sys-
tem, the scan tool or tester also indicates code P0700 simultaneously. Code P0700 means detection of some automatic
transmission problem on the PGM-Fl control system.
lf the self-diagnostic E indicator light does not blink. perform an inspection according to the table below.
NOTE:
. lf a custombr describes the symptom for code P1706 (6), P0725 (11) or P0715 (15), it will be necessary to recreate the
symptom by test-driving, then recheck the DTC,. Sometimes the E indicator light and the Malfunction Indicator Lamp (MlL) may come on simultaneously. lf so, check
the PGM-Fl system according to the DTC, then reset the memory by removing the BACK UP fuse in the under-dash
fuse/relay box for more than l0 seconds. Drive the vehicle for several minutes at a speed over 30 mph(50 km/h). then recheck the DTC.
. Disconnecting the BACK UP fuse also cancels the radio anti-theft code, preset stations and the clock setting. Get the
customer's code number, and make note of the radio presets before removing the fuse so you can reset them.

harness, disconnect the airbag Gonnectors.
a Whenever the ignition switch is ON (lll, or has been
turned OFF for less than three minutes, be carelul not
to bump the SRS unit; the airbags could accidentally
deploy and cause damage or iniuries.
a For additional precautions, lelel to the SRS sub-section
in section 23.
1. Remove the airbag assembly and steering wheel
(see page 17-25).

IABS Control
The ABS control unit detects the wheel speed based on the wheel sensor signal it received, then it calculates the vehiclespeed based on the detected wheel speed. The control unit detects the vehicle speed during deceleration based on therate of deceleration.
The ABS control unit calculates the slip rate of each wheel, and it transmits the control signal to the modulator unitsolenoid valve when the slip rate is high.
The pressure reduction control has three-modes: pressure reduction, pressure retaining, and pressure intensifying.
Self-diagnosis Function
The CPUS in the ABS control unit check the circuit of the system.
The self-diagnosis can be classifield into two categories.. Initial diagnosis: Performed right after the engine starts and until the ABS indicator gose off.. Regular diagnosis: Performed right after the initial diagnosis until the ignition switch isturnedoff.
On-board Diagnosis Function
The ABS control unit is connected to the data link connector fi6p).The ABS system can be diagnosed with the Honda PGM Tester.

Troubleshooting Precautions
ABS lndicator
1. lf the system is OK. the ABS indicator goes off two seconds after turning the ignition switch ON (ll) without starting
the engine, and then comes on again and goes off after two seconds. This occurs because the ABS control unit is
turned on bv the lG2 oower source.
2. The ABS indicator comes on when the ABS control unit detects a problem in the system. However, even though the
system is operating properly, the ABS indicator will come on under the following conditions.. Onlv drive wheels rotate
. One drive wheel is stuck
. Vehicle spin
. ABS continues to operate for a long time
. Signal disturbance
To determine the actual cause of problem. question the customer about the problem, taking these conditions into
consideration.
3. When a problem is detected and the ABS indicator comes on, there are cases when the indicator stays on until the
ignition switch is turned OFF, and cases when the indicator goes off automatically when the system returns to nor-
mal. For DTCS 61 and 62, the indicator goes off automatically when the system returns normal. For all other codes.
the indicator stays on until the ignition switch is turned OFF.
4. For DTCS 12, 14, 16, '18, 2'1,22, 23, 24,51,52 and 53, the indicator goes off when the vehicle is driven again and the
system is OK after the ignition switch is turned from OFF to ON (ll). However, if the DTC is erased, the CPU is reset
and the indicator goes off right after the engine is started if the system is OK.
Diagnostic Trouble Code (DTC)
1. lf the CPU cannot be actlvated and the indicator comes on, the DTC is not memorized.
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,
S6lt-dirgnosis
1. Self-diagnosis can be classifield into two categories.
. Initial diagnosis: Performed right afterthe enginestansand untiltheABS indicator goes off.. Regular diagnosis: Performed rightafterthe initial diagnosis untilthe ignition switch isturned OFF.
2. When a problem is detected by self-diagnosis, the system
. Turns the fail-safe relay OFF
. Turns the solenoid valve OFF
. Turns the oumo motor OFF
. Turns the ABS indicator ON
