Dtc P1655 Spi Communications Between Error With Psvi Chip (1.5L Sohc) - Daewoo CIELO EURO III Manual

SPI COMMUNICATIONS BETWEEN ERROR WITH PSVI CHIP
System Description
Engine Control Module (ECM) detects if Serial Peripher-
al Interface (SPI) communication between main CPU
and output driver I/C is corrupted. The ECM monitors
specific bits in the SPI message structure. If bits are cor-
rupted, fail counter incremented.
Conditions For Setting The DTC
D Ignition ON.
D Ignition voltage is greater than 11 volts.
Action Taken When The DTC Sets
D The Malfunction Indicator Lamp (MIL) will illuminate.
D The ECM will record operating conditions at the time
the diagnostic fails. This information will be stored in
the Freeze Frame and Failure Records buffers.
D A history DTC is stored.
Conditions For Clearing The DTC
D The MIL will turn off after four consecutive ignition
cycles in which the diagnostic runs without a fault
within the freeze frame conditions that the DTC failed.

Test Description
The number(s) below refer to specific step(s) on the
diagnostic table.
1. On-Board Diagnostic (EOBD) System Check
prompts the technician to complete some basic
checks and store the freeze frame and failure re-
cords data on the scan tool if applicable. This
creates an electronic copy of the data taken when
the malfunction occurred. The information is then
stored on the scan tool for later reference.
3. The replacement ECM must be reprogrammed. Re-
fer to the least Techline procedure for ECM repro-
gramming.
